dd29f9aa65 .NET: Hosted Agent Sample - Toolbox with various Auth (#5777) (#6018)
* .NET: Add Hosted-Toolbox-AuthPaths sample and auto-map /readiness with toolbox health gating (#5777)

Add a new hosted agent sample demonstrating five MCP tool authentication paths
(API key, agent MI, project MI, custom OAuth, literal token) via a Foundry Toolbox.

Package changes (Microsoft.Agents.AI.Foundry.Hosting):
- MapFoundryResponses now auto-maps GET /readiness via MapHealthChecks, idempotent
  across Tier 1/2 (AgentHost, already mapped) and Tier 3 (WebApplication, gap filled).
- AddFoundryResponses registers AddHealthChecks() so the pipeline is available.
- AddFoundryToolboxes registers FoundryToolboxHealthCheck on the /readiness aggregate,
  gating readiness on pre-registered toolbox startup outcome (per spec section 3.1).
- FoundryToolboxService now exposes StartupStatus and FailedToolboxNames properties.

New types:
- FoundryToolboxStartupStatus (public enum): Pending, Healthy, Failed, NoEndpoint.
- FoundryToolboxHealthCheck (internal IHealthCheck): adapts startup status to the
  AspNetCore HealthChecks pipeline with failed toolbox names in result data.

Tests:
- 3 new tests for /readiness auto-mapping (Tier 3 default, pre-mapped skip, idempotent).
- 4 new tests for FoundryToolboxHealthCheck (Pending, NoEndpoint, Failed, Healthy).
- 3 enhanced FoundryToolboxServiceTests with StartupStatus assertions.

* .NET: Align FoundryToolboxService with tools-integration-spec (#5777 Part A)

Bring Microsoft.Agents.AI.Foundry.Hosting's toolbox path into compliance with
tools-integration-spec.md sections 2-4, 6.3, and 9. Empirically validated
against tao-foundry-prj: the previous code (reading FOUNDRY_AGENT_TOOLSET_ENDPOINT,
which the platform never injects) silently registered zero tools in production.

Package changes (Microsoft.Agents.AI.Foundry.Hosting):

- FoundryToolboxService.StartAsync now derives the toolbox proxy base URL from
  the platform-injected FOUNDRY_PROJECT_ENDPOINT and constructs the per-toolbox
  URL as {FOUNDRY_PROJECT_ENDPOINT}/toolboxes/{name}/mcp?api-version={ApiVersion}
  per spec sections 2-3. The legacy FOUNDRY_AGENT_TOOLSET_ENDPOINT env var is
  removed outright (preview package, no production consumers).
- FoundryToolboxOptions.ApiVersion default flipped to 'v1' to match spec example.
- FoundryToolboxBearerTokenHandler always sends the mandatory
  Foundry-Features: Toolboxes=V1Preview header per spec section 2, merging any
  additional flags supplied via the FOUNDRY_AGENT_TOOLSET_FEATURES env var.
- FoundryToolboxBearerTokenHandler token scope changed from
  https://cognitiveservices.azure.com/.default to https://ai.azure.com/.default
  per spec section 4.
- FoundryToolboxBearerTokenHandler propagates W3C trace context (traceparent,
  tracestate, baggage) from Activity.Current per spec section 6.3.

Sample changes:

- Hosted-Toolbox-AuthPaths and Hosted-Toolbox Program.cs, README.md, and
  .env.example corrected to describe the actual env-var contract
  (FOUNDRY_PROJECT_ENDPOINT auto-injected; AZURE_AI_PROJECT_ENDPOINT as the
  local-dev fallback). Removes the misleading 'auto-injected by Foundry runtime'
  claims for FOUNDRY_AGENT_TOOLSET_ENDPOINT.
- Hosted-Toolbox-AuthPaths/agent.manifest.yaml declares the toolbox and model
  dependencies under resources[] per the AgentManifest schema so azd ai agent
  init users get them provisioned automatically.

Tests:

- 4 new FoundryToolboxServiceTests covering env-var derivation, EndpointOverride
  precedence, trailing-slash normalization, and the existing NoEndpoint behavior
  under the new env var name.
- 4 new FoundryToolboxBearerTokenHandlerTests covering token scope, mandatory
  feature header always present, header merging with override, no duplicate
  mandatory flag, trace context propagation from Activity.Current, and no
  override of caller-set traceparent.
- New FoundryProjectEndpointEnvFixture xUnit collection definition serializes
  env-var-mutating tests across FoundryToolboxServiceTests and
  FoundryToolboxHealthCheckTests, preventing parallel-execution races.
- FoundryToolboxHealthCheckTests adjusted for the new env var name.

* .NET: Drop ACA prereq from Hosted-Toolbox-AuthPaths README (#5777 Part B)

Empirically verified that any Azure Cognitive Services MCP endpoint already in
the Foundry project (e.g., a Language service MCP) accepts Entra tokens and can
serve Paths 2 and 3 without deploying a separate Azure MCP Server to ACA.

README updates:
- Step 0 rewritten: 'Identify an Entra-authenticated MCP target in your project'
  instead of 'Deploy Azure MCP Server to Azure Container Apps' (the original
  azmcp-foundry-aca-mi setup is now optional, not required).
- Auth-paths matrix updated to describe AAD-based connections targeting a
  Cognitive Services MCP URL (e.g., Language service) instead of an ACA URL.
- Step 2 connections table updated: the Entra ID category is now a single 'AAD'
  authType. The original 'Agent Identity' vs 'Project Managed Identity' as
  selectable connection sub-types is NOT exposed via the ARM control plane
  today; the platform selects the calling principal contextually. Both
  connections in the walkthrough share the same shape and target.
- Added an explicit RBAC note: the agent identity AND project MI must hold the
  required role (typically Cognitive Services User) on the target resource;
  without it the MCP server returns HTTP 401 even though the connection wiring
  is correct.
- Toolbox tool entries renamed lang_entra_agent / lang_entra_project to
  match the new connection names.

Empirical validation supporting these changes is captured in the session
plan.md (Part B addendum).

* .NET: Document correct connection shape for Hosted-Toolbox-AuthPaths Paths 2/3 (#5777)

Updates the sample README with the verified connection shape and RBAC procedure
for Microsoft Entra agent-identity and project-managed-identity MCP authentication:

- Connection authType values: AgenticIdentityToken (agent identity) and
  ProjectManagedIdentity (project MI), both with category=RemoteTool.
- Top-level audience property required; for Cognitive Services targets the value
  is https://cognitiveservices.azure.com.
- Connections created via ARM REST (the Foundry portal wizard does not yet
  expose these authTypes).
- RBAC grants target the project's shared agent identity blueprint principal
  (project.properties.agentIdentity.agentIdentityId) for Path 2 and the
  project's system-assigned MI (project.identity.principalId) for Path 3.
- Troubleshooting table updated with the audience-mismatch symptom and the
  startup-cache behavior of FoundryToolboxService.

* .NET: Drop Path 3 (project MI) and align with new agent model in Hosted-Toolbox-AuthPaths (#5777)

Updates the sample to use only the new Foundry agent object model and removes
the project managed identity path:

- Auth-path matrix reduced to four paths: key, Entra agent identity, custom
  OAuth, inline authorization. Project managed identity is moved into a note
  describing when it applies (multiple agents sharing access) rather than as
  a documented sample path.
- RBAC instructions reference the agent's own instance_identity.principal_id
  from the agent ARM resource (new agent object model) instead of the
  project's shared agent identity blueprint (legacy model).
- Step 2 (connections) creates only the AgenticIdentityToken connection.
- Step 3 (toolbox tools) lists four tool entries instead of five.
- Sample prompts and troubleshooting table updated to match.

* .NET: Restore Path 3 (project MI) to Hosted-Toolbox-AuthPaths matrix (#5777)

The sample's purpose is to enumerate every authentication path a Foundry toolbox
can drive, not to pick one. Path 3 belongs alongside the other four with
explicit guidance for when each path is the right choice.

- Path 3 (project managed identity, authType=ProjectManagedIdentity) restored
  to the matrix with a 'When to pick this' column.
- Step 2 (connections) provisions both lang-mcp-agent-id and lang-mcp-project-mi
  via ARM REST.
- Step 3 (toolbox) lists five tool entries (one per path).
- RBAC instructions cover both the agent's instance identity (Path 2) and the
  project's system-assigned MI (Path 3).
- Sample prompts include all five paths.
- Troubleshooting table updated accordingly.

* .NET: Fix duplicate line in Hosted-Toolbox-AuthPaths README (#5777)

* .NET: Fix broken markdown link to ToolCallingApprovalHostedAgentFixture (#5777)

* .NET: Fix relative path depth in markdown link (#5777)

* .NET: Address Copilot review feedback for #5777

- FoundryToolboxHealthCheck description: rename FOUNDRY_AGENT_TOOLSET_ENDPOINT
  → FOUNDRY_PROJECT_ENDPOINT (stale reference; operator-facing in /readiness body).
- FoundryToolboxStartupStatus.NoEndpoint XML doc: same rename.
- ServiceCollectionExtensions XML docs: same rename + URL shape update.
- Foundry.Hosting.IntegrationTests.TestContainer: remove explicit
  app.MapGet('/readiness') — now redundant + would conflict with the
  auto-mapped readiness route from MapFoundryResponses.
- Hosted-Toolbox-AuthPaths agent.manifest.yaml: parameterize TOOLBOX_NAME via
  {{TOOLBOX_NAME}} template substitution and declare it under parameters with a
  default of 'auth-paths-toolbox' so the README's 'use any name' guidance
  actually works for hosted deployments.

* .NET: Address Copilot review round 2 — fallback env + dedup + naming (#5777)

- FoundryToolboxService.StartAsync: fall back to AZURE_AI_PROJECT_ENDPOINT when
  FOUNDRY_PROJECT_ENDPOINT is absent. Matches the local-dev convention used by
  the samples and resolves the doc/code mismatch flagged in review.
- FoundryToolboxHealthCheck description updated for the fallback.
- AddFoundryToolboxes: guard against duplicate health-check registration via an
  explicit name-uniqueness check on HealthCheckServiceOptions.Registrations.
  AddCheck<T>(name, ...) does not dedupe by name, so repeated AddFoundryToolboxes
  calls would have registered multiple instances.
- FoundryToolboxOptions.EndpointOverride doc: clarify URL becomes
  {EndpointOverride}/toolboxes/{name}/mcp (was missing /toolboxes/ segment).
- Hosted-Toolbox sample (Program.cs + README): switch FOUNDRY_TOOLBOX_NAME to
  TOOLBOX_NAME (the FOUNDRY_* prefix is reserved by the platform), default
  changed from 'my-toolset' to 'my-toolbox', terminology updated from 'Toolset'
  to 'Toolbox'.
- FoundryToolboxServiceTests: 2 test renames to reflect what they actually
  assert (StartupStatus + FailedToolboxNames, not URL shape directly).
- Tests adjusted to clear both env vars in NoEndpoint scenarios.

* .NET: Fix stale NoEndpoint XML doc and misleading test comment (#5777)

Update FoundryToolboxStartupStatus.NoEndpoint XML doc to mention both
FOUNDRY_PROJECT_ENDPOINT and AZURE_AI_PROJECT_ENDPOINT (the service
checks both since the fallback was added).

Fix test comment that claimed URL derivation validation when the test
only asserts on StartupStatus and FailedToolboxNames.

* Remove OAuth consent path from AuthPaths sample, keep four working auth paths

The interactive OAuth identity passthrough path needs a protocol gap closed in the
hosting package (the proprietary oauth_consent_request item is not representable
through the OpenAI/MEAI abstractions), so it is deferred to a separate spike branch.

This strips the OAuth path from the AuthPaths sample, the companion REPL client, the
agent manifest, and the docs, then renumbers the inline Authorization path so the
sample teaches four contiguous paths: API key via connection, Entra agent identity,
Entra project managed identity, and inline Authorization (anti-pattern).

Package code is unchanged; the consent infrastructure already present in main stays
as baseline. Both samples build with --warnaserror and all 246 hosting unit tests pass.

* .NET: Drop project MI auth path and dedicated client from Hosted-Toolbox-AuthPaths (#5777)

Live validation against tao-foundry-prj showed the ProjectManagedIdentity
path failing with an unresolved token audience 401, so the sample now ships
three working auth paths instead of four: connection key, agent managed
identity, and inline Authorization.

Changes:
- Remove the project managed identity path from the AuthPaths sample matrix,
  prerequisites, connections, toolbox table, prompts, Program.cs instructions
  and agent.manifest.yaml.
- Delete the near duplicate Hosted-Toolbox-AuthPaths-Client project and remove
  it from the solution. The README now drives the agent with the shared
  SimpleAgent REPL via AsAIAgent(agentEndpoint).
- Correct the troubleshooting note: the Foundry toolbox tools/list is all or
  nothing, so one bad source returns -32007, fails startup, and returns 424
  for every path. Add the allowed_tools caveat that names must match the
  upstream server.
- Mark the toolbox startup status and health check experimental under
  AgentsAIExperiments (MAAI001) instead of AIOpenAIResponses, and update the
  package NoWarn set accordingly.

* .NET: Address PR review nits for Hosted-Toolbox-AuthPaths (#5777)

- Remove duplicated NU1903 comment in Foundry.Hosting csproj.

- Fix stale 'four-tool' cross-links in Hosted-Toolbox and Hosted-McpTools READMEs to describe the three-path toolbox driven by the shared SimpleAgent REPL.

Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

* .NET: Address toolbox startup-status review feedback (#5777)

- Rename FoundryToolboxStartupStatus.Failed to Unhealthy so it is the proper opposite of Healthy, and clarify the doc comment covers the partial-failure case.

- Raise the missing-endpoint toolbox log from Information to Warning, since enabling toolboxes is an explicit opt-in and a silently disabled toolbox warrants a higher-severity signal.

- Update unit tests and the AuthPaths README troubleshooting row accordingly.

* .NET: Reword toolbox-wiring comment to avoid hosting-layer internals (#5777)

dc4bafbc1e .NET: Add Hosted-AgentSkills sample with Foundry Skills integration (#6013)
* .NET: Add Hosted-AgentSkills sample for Foundry Skills integration

Add a new hosted agent sample that demonstrates how to load behavioral
guidelines from Foundry Skills at startup using AgentSkillsProvider and
the progressive disclosure pattern (advertise -> load on demand).

The sample:
- Downloads SKILL.md files from Foundry via ProjectAgentSkills SDK
- Extracts ZIP archives with zip-slip protection
- Wires skills into AgentSkillsProvider as an AIContextProvider
- Hosts the agent via the Responses protocol

Ships two Contoso Outdoors skills matching the Python sample (PR #5822):
- support-style: tone, formatting, signature guidelines
- escalation-policy: when and how to escalate tickets

Includes convenience provisioning gated behind PROVISION_SAMPLE_SKILLS
env var, clearly documented as NOT a production pattern.

Closes #5776

Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

* .NET: Add unit tests and integration test for Hosted-AgentSkills

Unit tests (14 tests, all passing):
- ZIP extraction with zip-slip guard (valid archive, traversal attack,
  sibling-prefix attack, directory entries)
- Skill name validation (rejects dots, separators, traversal patterns)
- AgentSkillsProvider with downloaded skills (advertises both skills,
  load_skill returns canary tokens, unknown skill returns error)

Container integration test:
- New 'agent-skills' scenario in the test container that creates
  Contoso Outdoors skills on disk and wires AgentSkillsProvider
- AgentSkillsHostedAgentFixture + 4 integration tests verifying:
  - Routine questions load support-style skill (STYLE-CANARY-3318)
  - Escalation triggers load escalation-policy (ESC-CANARY-7742)
  - Skills are advertised in system prompt
  - load_skill tool is invoked via FunctionCallContent

* .NET: Add smoke test, bootstrap, and docs for agent-skills integration

- Add scripts/smoke.ps1 for local Docker smoke testing: builds the
  contributor image, runs the container, verifies both skills are loaded
  via canary tokens (STYLE-CANARY-3318, ESC-CANARY-7742)
- Add 'agent-skills' to the bootstrap script scenario list
- Add agent-skills row to the integration test README scenarios table
- Exclude HostedAgentSkillsPatternTests from net472 (uses net8.0+ APIs)

Roger BarretoandGitHub aad20c2b33 .NET: Bump Azure.AI.Projects to 2.1.0-beta.2 and add agent-endpoint AsAIAgent path (#5899)
* .NET: Bump Azure.AI.Projects to 2.1.0-beta.2 and add agent-endpoint AsAIAgent path

Bumps Azure.AI.Projects to 2.1.0-beta.2 with the matching transitive pins (Azure.Core 1.55.0, System.ClientModel 1.11.0).

Foundry agent endpoint plumbing:
* FoundryAgent now routes the agent-endpoint constructor through the new GetProjectResponsesClientForAgentEndpoint helper.
* Adds an internal FoundryAgent ctor that takes an existing AIProjectClient plus a parsed agent endpoint so the public extension does not need to construct a second project client.
* Adds public AIProjectClient.AsAIAgent(Uri agentEndpoint, ...) extension. This is the path consumer samples are expected to use for hosted agents because version selection happens server-side.
* Trims the dangling "If you want to construct a FoundryAgent against a project endpoint..." sentence from ParseAgentEndpoint.

Unit tests:
* Four new tests in AzureAIProjectChatClientExtensionsTests cover the AIProjectClient.AsAIAgent(Uri agentEndpoint, ...) overload. 263/263 pass.

Consumer samples (Using-Samples):
* SimpleAgent and SessionFilesClient now read AZURE_AI_PROJECT_ENDPOINT and AZURE_AI_AGENT_NAME (both required, throw on missing), derive the agent endpoint with new Uri($"{projectEndpoint}/agents/{agentName}/endpoint/protocols/openai"), then call aiProjectClient.AsAIAgent(agentEndpoint, ...).
* SessionFilesClient README updated.

Contributor samples (responses/*):
* New HostedContributorRouteExtensions.MapDevTemporaryLocalAgentEndpoint() wildcard route extension so localhost contributor servers accept the per-agent OpenAI endpoint shape the production Hosted runtime exposes.
* All 11 contributor Program.cs files call MapDevTemporaryLocalAgentEndpoint() with a contributor-only warning comment.
* Hosted-Files and Hosted-AzureSearchRag were importing Hosted_Shared_Contributor_Setup but never calling AddDevTemporaryLocalContributorSetup(). Both now call it so HostedSessionIsolationKeyProvider resolves correctly in dev.
* Hosted-AzureSearchRag, Hosted-Files, Hosted-MemoryAgent csprojs drop stale VersionOverride="2.1.0-beta.1" pins.
* Hosted-AzureSearchRag and Hosted-Files csprojs add ProjectReference to Hosted_Shared_Contributor_Setup.
* Hosted-Observability/.dockerignore removed the out/ exclusion that was blocking COPY out/ . in Dockerfile.contributor.

Verified:
* Full solution-scoped build of changed projects: green.
* Scoped CI-parity dotnet format via WSL2 + Docker (mcr.microsoft.com/dotnet/sdk:10.0) over every changed csproj: clean.
* Foundry unit tests: 263/263.
* Contributor docker smoke for 8 hosted samples (publish + docker build + docker run + curl POST to the wildcard route): HTTP 200 / 500 with route matched.
* End-to-end smoke against the real Azure Foundry project with a fresh bearer token: Hosted-Files contributor container served HTTP 200, the agent invoked ListBundledFiles, and returned the expected file name.

* Address PR review: forward pipeline settings; add UTs

- CreateProjectClientOptions also carries RetryPolicy, NetworkTimeout, ClientLoggingOptions, MessageLoggingPolicy (was Transport+UserAgentApplicationId only).

- Make CreateProjectClientOptions internal so tests can verify the copy directly.

- Add AsAIAgent(Uri) UTs covering tools forwarding to inner ChatOptions and null tools handling.

- Add CreateProjectClientOptions UTs covering null caller and full pipeline-settings copy.

Roger BarretoandGitHub ad95f2f2fa .NET: Add Hosted-MemoryAgent sample with isolation key plumbing (#5692) (#5702)
* .NET: Add Hosted-MemoryAgent sample with isolation key plumbing (#5692)

Adds HostedSessionContext + HostedSessionIsolationKeyProvider in Microsoft.Agents.AI.Foundry.Hosting so AIContextProviders (notably FoundryMemoryProvider) can scope per user via the platform's x-agent-user-isolation-key / x-agent-chat-isolation-key headers.

- New types: HostedSessionContext (sealed), HostedSessionContextExtensions (public Get, internal Set), abstract HostedSessionIsolationKeyProvider (async), internal PlatformHostedSessionIsolationKeyProvider mapping ResponseContext.Isolation.

- AgentFrameworkResponseHandler now resolves the provider, tags fresh sessions, and validates resumed sessions against the live request (strict 403 'Hosted session identity context mismatch' on any mismatch; 500 on null keys).

- New shared sample project Hosted_Shared_Contributor_Setup hosts DevTemporaryTokenCredential and DevTemporaryLocalSessionIsolationKeyProvider plus AddDevTemporaryLocalContributorSetup. All 9 existing responses samples migrated to consume it so local runs keep working under the strict isolation contract.

- New Hosted-MemoryAgent sample: travel assistant wired through FoundryMemoryProvider with stateInitializer reading session.GetHostedContext().UserId. Includes Dockerfile, smoke.ps1, agent.yaml/manifest.

- New IT scenario 'memory' in Foundry.Hosting.IntegrationTests + MemoryHostedAgentFixture + MemoryHostedAgentTests. Verified end to end against the tao Foundry project.

- ADR 0026 captures the design tree.

* Address PR review feedback

- Dockerfile: add header noting it targets NuGet builds; contributors must use Dockerfile.contributor for ProjectReference source builds.

- PlatformHostedSessionIsolationKeyProvider: doc said 'returns context with empty values'; corrected to 'returns null' which the handler treats as 500.

- FakeHostedSessionIsolationKeyProvider: doc clarifies that null configurations are allowed for testing the handler error path.

- HostedSessionContextExtensions.SetHostedContext: enforce write-once with InvalidOperationException; doc + xml exception updated.

- AgentFrameworkResponseHandler: cache PlatformHostedSessionIsolationKeyProvider as static readonly to avoid per-request allocation.

- MemoryHostedAgentTests: tighten waits from 20s to 5s (FoundryMemoryProvider defaults UpdateDelay=0; ingestion ~3s).

- Sample Program.cs imports reordered to satisfy IDE0005.

* Add HostedFoundryMemoryProviderScopes built-in helpers (#5692)

Addresses review feedback from @lokitoth on Hosted-MemoryAgent/Program.cs:54.

- New HostedFoundryMemoryProviderScopes static class with PerUser, PerChat, PerUserAndChat factories returning Func<AgentSession?, FoundryMemoryProvider.State>.

- All helpers throw InvalidOperationException when GetHostedContext() is null, with a message pointing at writing a custom stateInitializer for non-hosted scenarios.

- New HostedFoundryMemoryScope enum and AddHostedFoundryMemoryProvider DI extension (two overloads: explicit AIProjectClient and DI-resolved). Singleton lifetime. Default scope = PerUser.

- Hosted-MemoryAgent sample and the memory IT scenario container both swap their inline lambdas for HostedFoundryMemoryProviderScopes.PerUser().

- 14 new unit tests (241/241 hosting unit tests pass).

* Replace HostedFoundryMemoryScope enum with Func<...> parameter (#5692)

Address PR review feedback from @westey-m: enums are a breaking-change hazard when extended, and the enum was redundant with the existing HostedFoundryMemoryProviderScopes static class.

- Delete HostedFoundryMemoryScope.cs.

- AddHostedFoundryMemoryProvider DI extensions now take Func<AgentSession?, FoundryMemoryProvider.State>? stateInitializer = null. When null, default to HostedFoundryMemoryProviderScopes.PerUser().

- Callers pick a built-in helper (PerUser/PerChat/PerUserAndChat) or pass a custom delegate. New built-ins are a single static method addition with zero impact on existing callers.

- Tests updated; 244/244 hosting unit tests pass.

* Fix isolation context resume for externally-created conversations (#5692)

Branch on the session's existing hosted-context (not on conversation_id presence) so a conversation provisioned externally (e.g. via conversations.CreateProjectConversationAsync) is treated as fresh on first hosted-agent request and stamped, rather than rejected with 403 hosted_session_identity_mismatch. Strict equality is preserved on real resume of an already-stamped session.

Also tighten dotnet/global.json to version 10.0.204 + rollForward latestPatch so local builds match the CI Docker image SDK and avoid 10.0.300 dotnet format stripping required usings.

* Revert global.json SDK pin to upstream (#5692)

The 10.0.204 + latestPatch pin from the previous commit broke the dotnet-format CI job (hostfxr_resolve_sdk2 could not find a compatible SDK in the mcr.microsoft.com/dotnet/sdk:10.0 image). Restore upstream 10.0.200 + minor; local Release builds with SDK 10.0.300 should set GITHUB_ACTIONS=true to bypass the auto-format-on-build target.

* .NET: Hosted Agents - RAG Sample with Azure AI Search (#5693)

Adds a Hosted-AzureSearchRag sample plus a live Foundry.Hosting integration
test scenario backed by a real Azure AI Search index.

Sample (Hosted-AzureSearchRag): keyword-only Azure AI Search via
SearchClient adapter into TextSearchProvider, scope-aware
DevTemporaryTokenCredential consuming AZURE_BEARER_TOKEN_FOUNDRY +
AZURE_BEARER_TOKEN_SEARCH for local Docker, Dockerfile + contributor
Dockerfile mirroring Hosted-TextRag.

Integration test: AzureSearchRagHostedAgentFixture extends the PR #5598
HostedAgentFixture with the new azure-search-rag scenario branch in the
shared test container; AzureSearchRagHostedAgentTests asserts the model
returns canary tokens (TR-CANARY-7821, SHIP-CANARY-4493) that exist only
in the seeded documents - real proof the agent grounded its answer in
retrieved content rather than training data.

Roger BarretoandGitHub 9faf52de4f .NET: Hosted-Files sample + AgentSessionFiles SDK companion + integration test (#5698)
* .NET: Add Hosted-Files sample + alpha AgentSessionFiles SDK companion + integration test

Closes #5691

- Hosted-Files server sample (mirrors python 06_files): 3 local tools reading
  the per-session \C:\Users\rbarreto sandbox volume.
- SessionFilesClient REPL companion: code-first equivalent of
  zd ai agent files upload using the alpha
  Azure.AI.Projects.AgentSessionFiles SDK (upload/ls/download/rm + session
  lifecycle with isolation key).
- session-files scenario added to the Foundry.Hosting.IntegrationTests
  multi-scenario harness (PR #5598): SessionFilesHostedAgentFixture +
  SessionFilesHostedAgentTests.UploadAndAgentReadsFileAsync, end-to-end
  validating upload then agent-reads-file (agent_session_id pinned via
  CreateResponseOptions.Patch). Bundled testdata is linked from the sample
  so there is a single source of truth.

* .NET: Hosted-Files: REPL companion now demonstrates file-as-knowledge end-to-end

Adds an 'ask <prompt>' command to SessionFilesClient that pins
agent_session_id (via CreateResponseOptions.Patch) so the agent invoked from
the REPL reads files this REPL just uploaded. Surfaces the file content as
agent knowledge in the same in-process loop instead of telling the user to
shell out to azd ai agent invoke.

* .NET: Reshape Hosted-Files sample - bake files into image, SessionFilesClient becomes thin chat REPL

The previous SessionFilesClient leaned on the alpha AgentSessionFiles SDK
to upload files at runtime, which made it diverge from the canonical
Using-Samples shape (SimpleAgent / SimpleInvocationsAgent: tiny chat REPLs).

This change:

- Bakes the sample resources/ directory into the published output via a
  Content Include in HostedFiles.csproj. Inside the container the files live
  at /app/resources/. Two local function tools (ListFiles, ReadFile) surface
  them to the model.
- Reshapes SessionFilesClient as a thin FoundryAgent chat REPL, identical
  shape to SimpleAgent. AGENT_ENDPOINT + AGENT_NAME, that is it.
- Demo flow: user asks 'Give me the total revenue in the contoso file' and
  the agent answers with the figure read from its bundled file. Validated
  end-to-end locally against Hosted-Files on http://localhost:60419.
- Bypasses SampleEnvironment alias on optional env vars to avoid stdin
  prompts when running unattended.

The Foundry.Hosting.IntegrationTests session-files scenario continues to
validate the alpha AgentSessionFiles SDK end-to-end (upload + agent reads
from session HOME) and is unchanged.

* .NET: Foundry.Hosting.IntegrationTests TestContainer - constrain session-files tools to $HOME

Addresses the path-traversal review comment on the session-files scenario:
ResolveSessionPath in TestContainer used to allow absolute paths and ..
traversals, which (when chained with indirect prompt injection in an
uploaded file) would let the model read or list arbitrary container files
via the ReadFile / ListFiles tools.

Mirrors the canonicalize + StartsWith(home) pattern from the framework's
own FileSystemAgentFileStore.ResolveSafePath: rejects rooted paths, calls
Path.GetFullPath, and verifies the result stays under $HOME, throwing
ArgumentException otherwise.

The Hosted-Files sample is already safe (uses Path.GetFileName which strips
any directory component) so no change there. The integration test continues
to upload and read 'contoso_q1_2026_report.txt', a single relative filename
which passes the new validation unchanged.

* .NET: SessionFilesHostedAgentTests - shrink to alpha SDK round-trip

The previous test attempted to pin agent_session_id into the /responses
payload via JsonPatch so the agent would read the file uploaded through
AgentSessionFiles. The Foundry alpha service now consistently rejects the
explicit-session-id pin with HTTP 400 conflict on /responses, regardless
of whether the session was pre-created via AgentAdministrationClient or
left to be auto-provisioned, so the agent leg of the test is no longer
reachable from the SDK surface.

Reshape the test to exercise what the alpha SDK actually guarantees:
create session, upload, list (assert presence + size), download (assert
deterministic token), delete (assert removed), cleanup. Everything stays
inside Azure.AI.Projects.Agents.AgentSessionFiles.

Verified live against tao-foundry-prj:
  UploadListDownloadAndDeleteAsync passed in 30s.
  Full Foundry.Hosting.IntegrationTests run: 25 total, 6 passed, 19
  skipped (existing placeholders), 0 failed.

* .NET: SessionFilesHostedAgentTests - rewrite as upload-then-FoundryAgent.RunAsync e2e

Per review feedback the integration test must validate the hosted agent
itself: client uploads a file via the alpha AgentSessionFiles SDK, then
FoundryAgent.RunAsync invokes the deployed agent and the agent's
container-side ReadFile tool surfaces the uploaded file content into the
response.

Test flow:
  1. agent.RunAsync(warmup) - platform provisions a per-session container.
  2. AgentAdministrationClient.GetSessionsAsync(latest) - resolve the
     just-provisioned agent_session_id.
  3. AgentSessionFiles.UploadSessionFileAsync - upload contoso file to
     that session, asserts BytesWritten + GetSessionFiles listing.
  4. agent.RunAsync(real prompt, options=PreviousResponseId chain) -
     chained to warmup so the platform routes back to the same container.
  5. Assert response contains '1,482.6' (deterministic token from file).
  6. Best-effort cleanup.

The test is annotated with [Fact(Skip=...)] right now: the Foundry alpha
service consistently returns HTTP 400 conflict on /responses requests
that link to a prior session via previous_response_id, conversation_id,
or agent_session_id pinning - verified across multiple retries with
multiple chaining strategies. Without that link we cannot route the
second invocation to the same container the file was uploaded to. When
the platform regression is resolved, removing the Skip will exercise
the full flow.

Full Foundry.Hosting.IntegrationTests run with this change: 25 total,
5 passed, 20 skipped (existing placeholders + this one), 0 failed.

* .NET: SessionFilesHostedAgentTests - end-to-end upload-then-FoundryAgent.RunAsync now passes

The blocker was a routing problem combined with a platform race:

1. Routing two /responses calls to the same per-session container.
   - agent_session_id pin in body -> 400 (platform treats it as create)
   - conversation_id created at project root -> 404 at agent endpoint
   - previous_response_id chain -> different session
   The working answer is to create the conversation on a per-agent
   ProjectOpenAIClient (AgentName option, URL becomes
   /agents/{name}/endpoint/protocols/openai/conversations) and pass that
   conversation_id on both calls. Both then resolve to the SAME
   x-agent-session-id (verified by capturing the response header).

2. Race after AgentSessionFiles upload. The upload mutates session/
   conversation revision; a /responses call issued immediately after
   400-conflicts with 'modified concurrently. Please retry.' Bounded
   exponential retry handles it (5 attempts, 2*attempt seconds).

Test flow:
  1. Create per-agent OpenAI client + ProjectConversationsClient + ProjectResponsesClient.
  2. CreateProjectConversationAsync on the per-agent client.
  3. Warm-up agent.RunAsync(prompt, ChatOptions { ConversationId = ... })
     - captures x-agent-session-id from the response header via a custom pipeline policy.
  4. AgentSessionFiles.UploadSessionFileAsync to that session id.
  5. ProjectResponsesClient.CreateResponseAsync (raw, retry-on-conflict)
     with the same conversation_id -> routes back to the same container.
  6. Assert response contains '1,482.6' (deterministic token from file).
  7. Cleanup: delete file, leave session for TTL.

Verified live against tao-foundry-prj:
  UploadedFile_IsReadByHostedAgentAsync passed in 24.9s.
  Full Foundry.Hosting.IntegrationTests run: 25 total, 6 passed, 19
  skipped (existing placeholders), 0 failed.

* .NET: address Copilot PR review findings

- agent.manifest.yaml: description + tags now reflect bundled-files agent (image-baked /app/resources), not the obsolete session-sandbox tools the prior shape claimed.
- SessionFilesHostedAgentTests: wrap test body in try/finally to call DeleteConversationAsync on the conversation we created (matches HappyPathHostedAgentTests pattern; prevents conversation leakage across runs).
- ResponseHeaderCapturePolicy: drop unused LastRequestBody capture left over from diagnosis.

Test still passes live (40s).

* .NET: Hosted-Files: split into bundled vs session-file tool pairs

The previous Hosted-Files agent only exposed bundled (image-baked) file
knowledge. The platform also surfaces session-uploaded files at \C:\Users\rbarreto
inside the per-session container per container-image-spec.md line 172
(verified live by SessionFilesHostedAgentTests). The sample now teaches
both patterns.

Two distinct tool pairs, each scoped to its own root:

  Bundled (image-baked):    ListBundledFiles, ReadBundledFile
                            -> /app/resources/ (BUNDLED_FILES_DIR override)

  Session-uploaded (\C:\Users\rbarreto): ListSessionFiles, ReadSessionFile
                            -> \C:\Users\rbarreto (default /home/session per container spec)

Security model -- distinct tools, distinct sandboxes:
  - Tool input is a fileName, not a path. Schema-level: model cannot
    request directories or traversals.
  - Path.GetFileName(input) strips any directory components.
  - Path.GetFullPath + StartsWith(root) check rejects anything outside
    the tool's root, mirroring FileSystemAgentFileStore.ResolveSafePath.
  - Read-only, non-recursive listing. No glob, no '..'.
  - Failures non-revealing: 'File <name> not found in <scope>.'

The two roots are physically isolated (image-baked vs platform-mounted
per-session volume). A bundled-root tool can never reach a session file
and vice-versa, even if the implementation has a bug.

README updated to document both flows, the security pattern, and cite
the container-image-spec.md line 172 contract for \C:\Users\rbarreto. Live IT
SessionFilesHostedAgentTests.UploadedFile_IsReadByHostedAgentAsync
re-passed in 42s after the change (TestContainer is unchanged; the
sample-agent split does not affect the IT).

Roger BarretoandGitHub eb709d8fc9 .NET: Update FoundryAgent to address HostedAgents strict URL routing (#5677)
* .NET: Foundry agent-endpoint constructor uses ProjectOpenAIClient directly to fix hosted-agent URL routing

Fixes the experimental FoundryAgent(Uri agentEndpoint, AuthenticationTokenProvider, ...)
constructor so it actually works against Foundry hosted agents.

The previous implementation routed through AzureAIProjectChatClient, which
internally called aiProjectClient.GetProjectOpenAIClient().GetProjectResponsesClientForAgent(...).
For an agent-endpoint URL of the canonical shape

  https://<host>/api/projects/<project>/agents/<agentName>/endpoint/protocols/openai

the chain produced

  POST https://<host>/api/projects/<project>/openai/v1/responses

(project-level path, no /agents/ segment). The Foundry service rejects this with
HTTP 400 "Hosted agents can only be called through the agent endpoint:
.../agents/<agentName>/endpoint/protocols/openai/responses".

The constructor also extracted the agent name via
agentEndpoint.Segments[^1].TrimEnd('/'), which returns "openai" (the last segment),
not the agent name.

What changed
- Public ctor signature: clientOptions parameter type changed from
  AIProjectClientOptions? to ProjectOpenAIClientOptions?. The constructor is
  fundamentally building a ProjectOpenAIClient; accepting AIProjectClientOptions
  was a leaky abstraction whose translation silently dropped any pipeline
  policies the caller added via AddPolicy(...). With the direct type, caller
  policies pass through to the per-agent traffic verbatim.
- Per-agent client construction: `new ProjectOpenAIClient(BearerTokenPolicy, ProjectOpenAIClientOptions)`
  with Endpoint and AgentName set, then `GetProjectResponsesClient().AsIChatClient()`.
  The SDK auto-appends ?api-version=v1 when AgentName is set.
- New private static ParseAgentEndpoint helper: single source of truth for both
  agent-name extraction and project-root derivation. Tolerates trailing slash,
  case variants on /agents/ and the suffix segment, strips query/fragment, and
  throws ArgumentException with paramName=nameof(agentEndpoint) for malformed input.
- Project-level client (used by CreateConversationSessionAsync) is built fresh
  from the derived project root with primitive properties copied
  (RetryPolicy/NetworkTimeout/Transport/UserAgentApplicationId) plus MEAI UA.
- New GetService<ProjectOpenAIClient>() entry alongside the existing
  GetService<AIProjectClient>() (the latter returns null in agent-endpoint mode
  since no AIProjectClient is constructed on that path).
- Endpoint and AgentName on caller-supplied ProjectOpenAIClientOptions are
  overridden by values derived from agentEndpoint.

Compatibility
- FoundryAgent is [Experimental(OPENAI001)]. No GA surface touched. The Foundry
  project does not maintain PublicAPI.*.txt baselines so there is no shipped
  baseline to update.
- The Microsoft.Agents.AI.Foundry csproj pins
  Azure.AI.Projects to VersionOverride 2.1.0-beta.1 (matching what the IT and
  hosting projects already use); the central pin in Directory.Packages.props
  stays at 2.0.0.
- WireClientHeaders from PR #5652 is invoked on the agent-endpoint path so
  per-call x-client-* headers behave identically across both ctors.

Tests
- 23 new unit tests in FoundryAgentTests.cs:
  - 12 for the agent-endpoint constructor (URL routing for non-streaming and
    streaming, conversations URL shape, MEAI UA stamping, caller-policy
    passthrough on the per-agent pipeline, Endpoint/AgentName override
    semantics, GetService matrix, ProjectOpenAIClient propagation,
    UserAgentApplicationId propagation, null-arg validation, ID/Name slug)
  - 9 for ParseAgentEndpoint (standard shape, trailing slash, casing,
    sovereign-cloud host without /api/projects/ literal prefix, special chars
    in agent name, query/fragment stripping, three negative cases)
  - 2 null-arg tests for the public ctor
- All 250 Microsoft.Agents.AI.Foundry.UnitTests pass (was 221 baseline plus
  29 from PR #5652 plus 23 new in this PR equals 273; pre-existing tests
  collapsed by the rebase merge keep the total at 250).
- All 225 Microsoft.Agents.AI.Foundry.Hosting.UnitTests pass; no behavioral
  change to the hosting layer.
- dotnet build clean across net8/9/10/netstandard2.0/net472 with
  TreatWarningsAsErrors=true.
- dotnet format --verify-no-changes clean for the touched src and test projects.

* .NET: Bump central Azure.AI.Projects pin to 2.1.0-beta.1 and flip Microsoft.Agents.AI.Foundry to preview

Required to fix the NU1109 downgrade chain that broke CI on the agent-endpoint
constructor rewire (#5677). Microsoft.Agents.AI.Foundry now depends on
ProjectOpenAIClientOptions.AgentName and the (AuthenticationPolicy, options)
constructor that only exist in Azure.AI.Projects 2.1.0-beta.1.

Changes:
* Directory.Packages.props: Azure.AI.Projects 2.0.0 -> 2.1.0-beta.1.
* Microsoft.Agents.AI.Foundry.csproj: drop IsReleased=true so the package ships
  as preview (matches the beta SDK we now depend on). Add a comment noting the
  flip is temporary and should revert once Azure.AI.Projects ships a stable
  2.1.0.
* Drop redundant VersionOverride="2.1.0-beta.1" from the 10 csprojs that had it
  as a workaround; the central pin now suffices.

Verified:
* dotnet build agent-framework-dotnet.slnx --warnaserror clean across all TFMs.
* Microsoft.Agents.AI.Foundry.UnitTests 250/250 pass.
* Microsoft.Agents.AI.Foundry.Hosting.UnitTests 211/211 pass.
* dotnet format --verify-no-changes clean for the touched src and test projects.

Roger BarretoandGitHub 705473c276 .NET: Add hosted agent observability sample (#5660)
* .Net: Add hosted agent observability sample

Mirrors the Python sample added in #5608 for Foundry hosted agents. The
.NET hosting library already wires OpenTelemetry automatically via
Microsoft.Agents.AI.Foundry.Hosting (ApplyOpenTelemetry) plus
Azure.AI.AgentServer.Core's AddAgentHostTelemetry, so no framework
changes are needed. The sample is documentation plus a runnable artifact
that produces an interesting span tree (invoke_agent / agent_invoke /
chat / execute_tool).

Adds Hosted-Observability under FoundryHostedAgents/responses with two
small tools (GetCurrentLocation, GetWeather), agent.yaml /
agent.manifest.yaml declaring OTEL_INSTRUMENTATION_GENAI_CAPTURE_MESSAGE_CONTENT
(the .NET equivalent of Python's ENABLE_SENSITIVE_DATA), Dockerfile +

* Catch agent errors and emit response.failed with real error message

Previously, unhandled exceptions from agent execution would bubble up
to the SDK orchestrator, which emits a generic 'An internal server
error occurred.' message — hiding the actual cause (e.g., 401 auth
failures, model not found, etc.).

Now AgentFrameworkResponseHandler catches non-cancellation exceptions
and emits a proper response.failed event containing the real error
message, making it visible to clients and in logs.

OperationCanceledException still propagates for proper cancellation
handling by the SDK.

Also bumps package version to 0.9.0-hosted.260403.2.

* Move Foundry Responses hosting into Microsoft.Agents.AI.Foundry package

Move source and test files from the standalone Hosting.AzureAIResponses project
into the Foundry package under a Hosting/ subfolder. This consolidates the
Foundry-specific hosting adapter into the main Foundry package.

- Source: Microsoft.Agents.AI.Foundry.Hosting namespace
- Tests: merged into Foundry.UnitTests/Hosting/
- Conditionally compiled for .NETCoreApp TFMs only (net8.0+)
- Deleted standalone Hosting.AzureAIResponses project and test project
- Updated sample and solution references

* Fix model override bug and add client REPL sample

- InputConverter: stop propagating request.Model to ChatOptions.ModelId
  Hosted agents use their own model; client-provided model values like
  'hosted-agent' were being passed through and causing server errors.
- Add FoundryResponsesRepl sample: interactive CLI client that connects
  to a Foundry Responses endpoint using ResponsesClient.AsAIAgent()
- Bump package version to 0.9.0-hosted.260403.1

* Catch agent errors and emit response.failed with real error message

Previously, unhandled exceptions from agent execution would bubble up
to the SDK orchestrator, which emits a generic 'An internal server
error occurred.' message — hiding the actual cause (e.g., 401 auth
failures, model not found, etc.).

Now AgentFrameworkResponseHandler catches non-cancellation exceptions
and emits a proper response.failed event containing the real error
message, making it visible to clients and in logs.

OperationCanceledException still propagates for proper cancellation
handling by the SDK.

Also bumps package version to 0.9.0-hosted.260403.2.

- Server-side MCP: HostedMcpServerTool delegates tool discovery and
  invocation to the LLM provider (Responses API), no local connection

Includes DevTemporaryTokenCredential for Docker local debugging,
Dockerfile.contributor for ProjectReference builds, and the openai/v1
route mapping for AIProjectClient compatibility in Development mode.

Add InMemoryAgentSessionStore registration to all ServiceCollection
setups in AgentFrameworkResponseHandlerTests and WorkflowIntegrationTests.
This is needed after the AgentSessionStore infrastructure was introduced
in the responses-hosting feature. Tests still have NotImplementedException
stubs for CreateSessionCoreAsync which will be fixed when the session
infrastructure is fully available.

* Add Invocations protocol samples (hosted echo agent + client) (#5278)

Add Hosted-Invocations-EchoAgent: a minimal echo agent hosted via the
Invocations protocol (POST /invocations) using AddInvocationsServer and
MapInvocationsServer, bridged to an Agent Framework AIAgent through a
custom InvocationHandler.

Add SimpleInvocationsAgent: a console REPL client that wraps HttpClient
calls to the /invocations endpoint in a custom InvocationsAIAgent,
demonstrating programmatic consumption of the Invocations protocol.

Both samples default to port 8088 for consistency with other hosted
agent samples.

* Restructure FoundryHostedAgents samples into invocations/ and responses/

Align dotnet hosted agent samples with the Python side (PR #5281) by
reorganizing the directory structure:

- Remove HostedAgentsV1 entirely (old API pattern)
- Split HostedAgentsV2 into invocations/ and responses/ based on protocol
- Move Using-Samples accordingly (SimpleAgent to responses, SimpleInvocationsAgent to invocations)
- Update slnx with new project paths and add previously missing invocations projects
- Update README cd paths from HostedAgentsV2 to invocations or responses
- Rename .env.local to .env.example to match Python naming convention
- Fix format violations in newly included invocations projects

* Remove launchSettings, use .env for port configuration

- Delete all launchSettings.json files (port 8088 now comes from ASPNETCORE_URLS in .env)
- Add DotNetEnv to Hosted-Invocations-EchoAgent so it loads .env like the responses samples
- Create .env.example for EchoAgent with ASPNETCORE_URLS and ASPNETCORE_ENVIRONMENT
- Add AGENT_NAME to ChatClientAgent and FoundryAgent .env.example (required by those samples)
- Add AZURE_BEARER_TOKEN=DefaultAzureCredential to all .env.example files
- Update DevTemporaryTokenCredential in all 6 samples to treat the sentinel value
  as unavailable, allowing ChainedTokenCredential to fall through to DefaultAzureCredential
- Update EchoAgent README with Configuration section

* Use placeholder for AGENT_NAME in Hosted-FoundryAgent .env.example

* Move FoundryResponsesHosting to responses/Hosted-WorkflowHandoff, use GetResponsesClient

* Rename Hosted-Workflows to Hosted-Workflow-Simple, Hosted-WorkflowHandoff to Hosted-Workflow-Handoff

* Remove FoundryResponsesRepl and empty FoundryResponsesHosting directory

* Add Dockerfiles, README, agent yamls and bearer token support to Hosted-Workflow-Handoff

- Add Dockerfile and Dockerfile.contributor for Docker-based testing
- Add agent.yaml and agent.manifest.yaml with triage-workflow as primary agent
- Add README.md following sibling pattern, noting Azure OpenAI vs Foundry endpoint
- Add DevTemporaryTokenCredential and ChainedTokenCredential for Docker auth
- Register triage-workflow as non-keyed default so azd invoke works without model
- Update .env.example with AZURE_BEARER_TOKEN sentinel
- Add .gitignore to 04-hosting to suppress VS-generated launchSettings.json
- Fix docker run image name in Hosted-Workflow-Simple README

* Fix AgentFrameworkResponseHandlerTests: implement session methods in test mock agents

* .NET: Auto-instrument resolved AIAgents with OpenTelemetry for Foundry Hosted Agents (#5316)

* Auto-instrument resolved AIAgents with OpenTelemetry using Core ResponsesSourceName

* Add OTel telemetry capture tests for Foundry hosted agent handler

* Net: Prepare Foundry Preview Release (#5336)

* Prepare Foundry preview release 1.2.0-preview.*

Bump VersionPrefix to 1.2.0 and update the preview stamp date. Invert packaging opt-in so only the Foundry preview set produces NuGet packages:

- Microsoft.Agents.AI.Abstractions

- Microsoft.Agents.AI

- Microsoft.Agents.AI.Workflows

- Microsoft.Agents.AI.Workflows.Generators

- Microsoft.Agents.AI.Foundry

Flip IsReleased=false on the preview set so they pick up the -preview.YYMMDD.N suffix. Gate GeneratePackageOnBuild on IsPackable=true. Remove the global IsPackable=true from nuget-package.props so the repo-level default (false) applies to everything else.

* Lower preview VersionPrefix to 0.0.1

Retroactive preview publish: bump VersionPrefix and GitTag from 1.2.0 to 0.0.1 so the 5 Foundry preview packages emit as 0.0.1-preview.260417.1.

* Net: Publish all packages as 0.0.1-preview.260417.2 (#5341)

Revises the Foundry pre-release approach to publish ALL normally packable src projects as preview packages stamped 0.0.1-preview.260417.2, including projects previously flagged IsReleased=true or with a non-default VersionSuffix (rc/alpha).

nuget-package.props:

- Collapse the four conditional PackageVersion expressions (IsReleaseCandidate, VersionSuffix, default preview, IsReleased stable) into a single unconditional 0.0.1-preview.260417.2. On this preview-only branch every package ships with the same pre-release stamp regardless of per-project flags.

- Restore the global IsPackable=true default (offsetting the repo-wide IsPackable=false in Directory.Build.props). Projects that opt out (Mem0, Declarative) already set IsPackable=false AFTER importing this file so they remain non-packable.

- Remove the IsReleased-gated EnablePackageValidation line. Package validation does not apply to a 0.0.1 preview.

csproj reverts (Abstractions, Agents.AI, Workflows, Workflows.Generators, Foundry):

- Revert the IsPackable=true opt-in block introduced in #5336 (now redundant since the props default is true again).

- Restore IsReleased=true to its pre-PR value. The setting is now a no-op because the props no longer branches on it.

* Bump preview version to 260420.1 and fix AgentServer package deps (#5367)

- Bump PackageVersion to 0.0.1-preview.260420.1
- Bump Azure.AI.AgentServer.Core beta.21 -> beta.22 (required by
  Azure.AI.AgentServer.Responses beta.3)
- Replace AgentHostTelemetry.ResponsesSourceName with local constant
  (type made internal in AgentServer.Core beta.22)

* .NET: Hosted agents toolbox support (#5368)

* feat: Add Foundry Toolbox (MCP) support to AgentFrameworkResponseHandler

Adds support for Foundry Toolsets MCP proxy integration in the hosted agent
response handler. Toolsets connect at startup via IHostedService, gating the
readiness probe per spec §3.1. MCP tools are injected into every request's
ChatOptions and OAuth consent errors (-32006) are intercepted and surfaced as
mcp_approval_request + incomplete SSE events.

New files:
- FoundryToolboxOptions.cs: configuration POCO for toolset names and API version
- FoundryToolboxBearerTokenHandler.cs: DelegatingHandler with Azure Bearer token
  auth, Foundry-Features header injection, and 3x exponential backoff on 429/5xx
- McpConsentContext.cs: AsyncLocal-based per-request consent state shared between
  the tool wrapper and the response handler
- ConsentAwareMcpClientTool.cs: AIFunction wrapper that catches -32006 errors and
  signals consent via shared state and linked CancellationTokenSource
- FoundryToolboxService.cs: IHostedService that creates McpClient per toolset at
  startup and exposes cached tools

Modified files:
- AgentFrameworkResponseHandler.cs: injects toolbox tools into ChatOptions, sets
  up linked CTS consent interception, emits mcp_approval_request on -32006
- ServiceCollectionExtensions.cs: adds AddFoundryToolboxes(params string[]) extension
- Microsoft.Agents.AI.Foundry.csproj: adds ModelContextProtocol and Azure.Identity
  dependencies under NETCoreApp condition

Sample:
- Hosted-Toolbox: minimal hosted agent sample using AddFoundryToolboxes

* Rename toolset to toolbox in user-facing API; rename ConsentAwareMcpClientTool to ConsentAwareMcpClientAIFunction

* Add HostedMcpToolboxAITool for client-selectable Foundry toolboxes

Introduces HostedMcpToolboxAITool, a marker tool subclassing HostedMcpServerTool that rides the OpenAI Responses 'mcp' wire format to let clients request a specific Foundry toolbox per request.

- New FoundryAITool.CreateHostedMcpToolbox(name, version?) factory.

- FoundryToolboxOptions.StrictMode (default true) rejects unregistered toolboxes; set to false to allow lazy-open on first use.

- FoundryToolboxService.GetToolboxToolsAsync(name, version?) resolves cached or lazy-opened MCP tools.

- AgentFrameworkResponseHandler parses request.Tools for foundry-toolbox://name[?version=v] markers and injects resolved tools per request, merging with pre-registered ones.

- Unit tests for marker parsing and strict-mode resolution.

* Bump Azure.AI.Projects to 2.1.0-alpha; add ToolboxRecord/ToolboxVersion factory overloads + tests

* Fix PR review issues: retry off-by-one, URI encoding, docs, tests, build

- Fix off-by-one in FoundryToolboxBearerTokenHandler retry loop (4 attempts → 3)
- URI-encode version parameter in HostedMcpToolboxAITool.BuildAddress
- Add XML doc clarifying version pinning is reserved for future use
- Add comment clarifying AddHostedService deduplication safety
- Fix DevTemporaryTokenCredential expiry to use DateTimeOffset.MaxValue
- Fix AgentCard ambiguity in A2AServer sample with using alias
- Add 18 new unit tests for retry handler and ReadMcpToolboxMarkers

* Split Foundry into stable V1 and preview Hosting package

Extract hosted agent functionality from Microsoft.Agents.AI.Foundry into a
new Microsoft.Agents.AI.Foundry.Hosting preview package. This resolves NU5104
build errors caused by the stable Foundry package depending on prerelease
Azure SDK packages (Azure.AI.AgentServer.Responses, Azure.AI.Projects beta).

Changes:
- Create Microsoft.Agents.AI.Foundry.Hosting with VersionSuffix=preview,
  targeting .NET Core only (net8.0/9.0/10.0)
- Move all Hosting/ source files to the new project
- Move ToolboxRecord/ToolboxVersion overloads to FoundryAIToolExtensions
- Revert Azure.AI.Projects to 2.0.0 in Directory.Packages.props;
  Hosting uses VersionOverride for 2.1.0-beta.1
- Clean V1 Foundry csproj: remove beta deps, ASP.NET Core ref, hosting conditionals
- Update 8 hosted agent sample projects to reference Foundry.Hosting
- Split unit tests: ToolboxRecord/ToolboxVersion tests moved to Hosting/
- Add Foundry.Hosting to solution file

- Fix McpConsentContext XML doc: 'Thread-static' -> 'Async-local' (AsyncLocal
  flows with ExecutionContext, not thread-static)
- Expand UserAgentMiddleware test regex to match prerelease versions (e.g. 1.0.0-rc.4)
- Propagate CancellationToken in AgentFrameworkResponseHandler session save

* Remove unnecessary MEAI001 suppression from stable Foundry package

MEAI001 was a leftover from when Hosting code lived in the same project.
The stable V1 Foundry package builds clean without it, and suppressing
experimental diagnostics in a released package can hide unintentional
exposure of experimental APIs to consumers.
