* Adding support for "wait for response" when invoking workflow http endpoint.
* update changelog.
* PR comment fixes.
* Address PR review feedback.
- Return 404 Not Found when no orchestration with the given ID exists
- Return 200 OK for failed workflows (the HTTP operation succeeded;
the workflow outcome is conveyed via the response body)
- Rename 'status' to 'workflowStatus' in WorkflowRunResponse to avoid
inconsistency with AgentRunSuccessResponse which uses integer status
- Add optional 'error' field (omitted from JSON when null) to
WorkflowRunResponse for failed workflow details
* Bump OpenTelemetry packages to 1.15.3 to fix known vulnerabilities
Update OpenTelemetry packages from 1.15.0 to 1.15.3 in Directory.Packages.props
to resolve NU1902 warnings-as-errors for CVEs GHSA-g94r-2vxg-569j,
GHSA-mr8r-92fq-pj8p, and GHSA-q834-8qmm-v933.
Add explicit PackageReference for OpenTelemetry.Exporter.OpenTelemetryProtocol
in Foundry.Hosting and OpenTelemetry.Api + OpenTelemetry.Exporter.OpenTelemetryProtocol
in Hosted-Invocations-EchoAgent to override transitive 1.15.0 resolution in
projects with CentralPackageTransitivePinningEnabled=false.

* Add DI wiring verification tests for AddA2AServer
Add three tests to A2AServerServiceCollectionExtensionsTests that verify
custom keyed services are actually wired through to the A2AServer, not
just that the server resolves non-null:
- Custom IAgentHandler: verifies the keyed handler is invoked when
processing a SendMessageRequest instead of the default A2AAgentHandler.
- Custom AgentSessionStore (no handler): verifies the keyed session
store's GetSessionAsync is called during request processing when no
custom handler is registered.
- Default stores end-to-end: verifies the InMemoryAgentSessionStore and
InMemoryTaskStore defaults successfully process a request. Uses a new
CreateAgentMockForRequests helper that includes SerializeSessionCoreAsync
setup needed by InMemoryAgentSessionStore.
All tests call A2AServer.SendMessageAsync directly (no HTTP layer needed)
and use CancellationToken timeouts to guard against hangs.

OperationCanceledException still propagates for proper cancellation

* 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

* 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.

* refactor: remove dead code
* refactor: remove ignore YieldsMessageAttribute
- the correct one to use is YieldsOutputAttribute
- fixes a comment that mistakenly refers to `.YieldsMessage()` which does not exist.
* fix: ChatForwardingExecutor does not use correct role for string messages
- make ChatForwardingExecutor use its configured role for string messages rather than always use ChatRole.User
- add ChatForwardingExecutor tests
* fixup: remove unused attribute
* test: Add tests for failure when .AsAgent used on a non-ChatProtocol workflow
* test: Add FunctionExecutor tests
- also fixes Send and YieldOutput type registration for synchronous output-returning delegates
* test: Suppress CodeCoverage for obsolete names
* fix: Re-add Obsolete attributes
- avoid hard-breaking change
- properly notify users that these attributes get ignored
Some providers, e.g. Gemini, do not use the CallId mechanism to disambiguate simultaneous function calls. This can result in message lists containing multiple turn to fail to filter properly.
The fix is to take advantage of the expectation that Handoff Orchestration is a "single-speaker" flow, which only has a single active AIAgent per "turn" and an agent's turn is not finished until all outstanding function calls are finished.
This allows us to expect that any ambiguous-CallId FunctionCallContent are either in separate turns or will have had a response before the next issued call with the same Id.

* remove unnecessary net472 framework condition from sample csproj files
These projects only target net10.0, so the
Condition="'$(TargetFramework)' != 'net472'" on ItemGroup is unnecessary.
* update sample model name from gpt-4.1 to gpt-5.4
Use a more up-to-date model name in the DevUI integration samples.
* Revert "remove unnecessary net472 framework condition from sample csproj files"
This reverts commit 08cf41253b.
* fix: use TargetFrameworks to override multi-targeting from Directory.Build.props
The parent Directory.Build.props sets TargetFrameworks to net10.0;net472,
which overrides the singular TargetFramework in each csproj. Use the plural
TargetFrameworks property set to net10.0 only to properly override it, and
remove the now-unnecessary net472 condition on ItemGroup.

* fix: Add session support for Handoff-hosted Agents
In order to better support using `Workflows` hosted as `AIAgents` inside of Handoff workflows, we need to make proper use of AgentSession. This causes potential issues around checkpointing and making sure that we properly compute only the new incoming messages for each agent invocation.
* fix: AgentSession checkpointing using AIAgent's Serialize/Deserialize methods
We cannot rely on implicit serialization through `HandoffHostState` because we are missing type information.
* fix: Thread safety issue in `MultiPartyConversation.AllMessages`
* fix: Enable unwrapping of FunctionResultContent when ExternalRequest was wrapped into FunctionCallContent
* fix: Foundry Agents without description in Handoff
Foundry Agents without a description set will return an empty string (rather than null) for the description. This was breaking the fallback logic for `handoffReason`.
* test: Add unit tests
* Foundry Evals integration for .NET
- Core evaluation framework: EvalItem, LocalEvaluator, FunctionEvaluator, EvalChecks
- IAgentEvaluator interface with MeaiEvaluatorAdapter bridge
- AgentEvaluationExtensions for agent.EvaluateAsync() overloads
- FoundryEvals wrapping MEAI quality/safety evaluators
- ConversationSplitters (LastTurn, Full) and IConversationSplitter
- EvalItem.PerTurnItems() for multi-turn decomposition
- HasImageContent for multimodal content detection
- WorkflowEvaluationExtensions for per-agent workflow evaluation
- 7 eval samples mirroring Python parity:
02-agents/Evaluation: SimpleEval, ExpectedOutputs, Multimodal
03-workflows/Evaluation: WorkflowEval
05-end-to-end/Evaluation: FoundryQuality, MixedProviders, ConversationSplits
- Comprehensive unit tests (1958 passing)

* Rewrite FoundryEvals to use real Foundry Evals API
Replace MEAI evaluator shim with actual OpenAI EvaluationClient protocol
methods. FoundryEvals now creates eval definitions, submits runs, polls
for completion, and fetches per-item results server-side.
- New constructor: FoundryEvals(AIProjectClient, model, evaluators)
- Add FoundryEvalConverter for MEAI ChatMessage -> Foundry JSON format
- Add EvalId, RunId, ReportUrl to AgentEvaluationResults
- All 20 built-in evaluator constants now work (agent, tool, quality, safety)
- Remove Microsoft.Extensions.AI.Evaluation.Quality/Safety dependencies
- Update all samples for new constructor (no more ChatConfiguration)
- Replace BuildEvaluators tests with ResolveEvaluator tests

- Add guard clauses for pollIntervalSeconds/timeoutSeconds <= 0
- Fix double TryGetProperty for passed field parsing
- Throw on all-tool-evaluators with no tool definitions
- Fix XML doc (default 300s, not 180s)
New tests (30 added, 1989 total):
- EvalChecks: NonEmpty, ContainsExpected (pass/fail/skip/case),
HasImageContent, ToolCallsPresent
- FoundryEvalConverter: ConvertMessage (text, image, function call,
function results fan-out, empty fallback, mixed content),
ConvertEvalItem, BuildTestingCriteria (quality/agent/tool/groundedness
data mappings), BuildItemSchema

- Change EvalChecks.ContainsExpected to return Passed=false when no
ExpectedOutput (was silently passing, masking misconfiguration)
- Add EvalItem constructor tests with LastTurn/Full/null splitters
- Add FoundryEvalConverter.ConvertMessage DataContent (base64 image) test
- Add ExtractAgentData tests with ChatMessage, list, and AgentResponse data
Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
* Fix review: conversation fidelity, eval caching, fallback tests
- WorkflowEvaluationExtensions: preserve full response messages (tool calls,
intermediate) instead of synthetic 2-message conversation. Cast completed
Data to AgentResponse and use Messages when available, fallback to text.
- FoundryEvals: cache evalId per schema shape (hasContext, hasTools) so
subsequent EvaluateAsync calls create runs under the same eval definition.
- MeaiEvaluatorAdapter: code already correctly passes queryMessages (not full
conversation) to IEvaluator — no change needed, verified by inspection.
- Add tests: AgentResponse full messages preservation, unknown object
ToString() fallback for ExtractAgentData.

Introduce internal FoundryEvalWireModels.cs with compile-time-safe types
for the OpenAI Evals API wire format. The OpenAI .NET SDK (2.9.1) only
provides protocol-level methods with BinaryContent/ClientResult — no
typed request models. These internal models replace scattered dictionary
literals with [JsonPropertyName]-annotated classes, giving:
- Compile-time safety (typos become build errors)
- Single point of change when the API evolves
- IntelliSense discoverability
- Cleaner serialization via JsonPolymorphic for content items
Models: WireContentItem hierarchy (text, image, tool_call, tool_result),
WireMessage, WireEvalItemPayload, WireTestingCriterion, WireItemSchema,
WireCreateEvalRequest, WireCreateRunRequest, and data source variants.

* Skip metric when Foundry returns neither score nor passed
When an evaluator returns no score and no passed value, the previous
code created BooleanMetric(name, false), which falsely failed items
via ItemPassed. Now we skip the MEAI metric entirely for indeterminate
results — the raw data remains available in DetailedItems for diagnostics.

* Address PR #4914 review comments: fix tool evaluator bug and add tests
- Fix duplicate ToolCallAccuracy: resolve evaluator names before checking
against ToolEvaluators set (Comment 2)
- Make FilterToolEvaluators internal for testability; add tests for the
ArgumentException edge case when all evaluators are tool-type (Comment 3)
- Add CancellationToken test for LocalEvaluator (Comment 4)
- Add EvaluateAsync integration test on Run with sequential workflow and
per-agent SubResults verification (Comment 5)

* Address Peter's review comments on PR #4914
- Add trailing newline to Evaluation_FoundryQuality.csproj (Comment 6)
- Make evaluator name lookups case-insensitive: switch BuiltinEvaluators,
ToolEvaluators, AgentEvaluators, and ResolveEvaluator's StartsWith check
from Ordinal to OrdinalIgnoreCase (Comment 7)
- Add Trace.TraceWarning when Foundry returns fewer results than submitted
items, indicating expected vs actual count before padding (Comment 8)

* Add Microsoft.Extensions.AI.Evaluation packages to Directory.Packages.props
These were removed in #5269 as unused, but are needed by the Foundry
and core evaluation integration added in this PR.

* Fixes an intermittent checkpoint-restore race in in-process workflow runs.
* feat: Refactor Handoff Orchestration and add HITL support
* Change HandoffAgentExecutor to use factory-based instantiation
* Extract shared request collection logic in AIAgentUnservicedRequestsCollector
* Refactor HandoffAgentExecutor to use the "ContinueTurn" pattern as in AIAgentHostExecutor
* fix: Remove '$' from exception strings
Rename authored identifiers, XML docs, log messages, and comments
from 'folder' to 'directory' across the file skills codebase for
consistency with the agentskills.io specification and .NET conventions.
Public API changes (experimental):
- ScriptFolders → ScriptDirectories
- ResourceFolders → ResourceDirectories
.NET BCL API calls (Directory.Exists, Path.GetDirectoryName, etc.)
were already using 'directory' and are unchanged.

* support reflection for discovery of resources and scripts in class-based skills
* fix format issues
* refactor samples to use reflection
* Validate resource member signatures during discovery
Add discovery-time validation in AgentClassSkill.DiscoverResources() to
fail fast when [AgentSkillResource] is applied to members with incompatible
signatures:
- Reject indexer properties (getter has parameters)
- Reject methods with parameters other than IServiceProvider or
CancellationToken
Throws InvalidOperationException with actionable error messages instead of
allowing silent runtime failures when ReadAsync invokes the AIFunction with
no named arguments.

* .NET: Add JsonSerializerOptions support to programmatic skill APIs
Allow callers to pass custom JsonSerializerOptions when creating inline
resources and scripts via AgentInlineSkill, AgentClassSkill,
AgentInlineSkillResource, and AgentInlineSkillScript. A skill-level
default can be set on AgentInlineSkill and overridden per-resource/
script call.

* fix: Concurrent Workflow Sample
* Switch to using Azure AI Projects APIs
* Remove agent streaming outputs by changing emitEvents to false on TurnToken
* Disable forwarding input from agent host executors
* Make output format more legible
* refactor: Update Concurrent sample to use message delivery event callback
Adds a public CreateSessionAsync(string conversationId, CancellationToken)
method to FoundryAgent that delegates to the inner ChatClientAgent,
allowing users to create sessions with existing server-side conversation IDs.
Fixes#5138

* Fix mixed path separators in skill folder discovery on .NET Framework
Path.Combine with forward-slash folder names (e.g. "scripts/f1") produces
mixed separators on Windows, causing the StartsWith containment check to
fail against Path.GetFullPath-resolved file paths. Wrap in Path.GetFullPath
to canonicalize separators before the containment comparison.
