4b5a8478de .NET: Hosting updates to declarative workflows (#5589)
* Make DeclarativeWorkflowExecutor ChatProtocol-compatible for AsAIAgent hosting

Extends the existing DeclarativeWorkflowExecutor<TInput> root executor with
additional ChatProtocol-compatible input routes (string, ChatMessage,
IEnumerable<ChatMessage>, ChatMessage[], TurnToken) so that workflows built
via DeclarativeWorkflowBuilder.Build<TInput>(...) work both for direct
invocation and when hosted via Workflow.AsAIAgent(...).

- Each input message advances the declarative graph immediately; the
  TurnToken that the host sends after the message batch is treated as a
  no-op since the message has already been processed.
- Conversation id resolution now prefers persisted workflow system state,
  then DeclarativeWorkflowOptions.ConversationId, then a newly created
  conversation. This makes multi-turn invocations reuse the prior
  conversation rather than creating a fresh one each turn.
- The separate DeclarativeChatProtocolStartExecutor and
  DeclarativeWorkflowBuilder.BuildChatProtocol overloads introduced
  earlier are removed; callers continue to use Build<TInput>(...).

* fix: use DeclarativeWorkflowContext when reading workflow conversation id

GetWorkflowConversation() requires a DeclarativeWorkflowContext (it calls ReadState which dynamic-casts via the DeclarativeContext helper). The chat-protocol auxiliary handlers receive a BoundWorkflowContext, so calling the extension on the raw IWorkflowContext throws `Invalid workflow context: BoundWorkflowContext`. Use the wrapped declarativeContext that we already constructed.

* fix: surface ExecutorFailedEvent as ErrorContent in AsAIAgent response

WorkflowSession.InvokeStageAsync only converted WorkflowErrorEvent into an ErrorContent payload. ExecutorFailedEvent fell through to the default branch which emits an empty AgentResponseUpdate carrying the event in RawRepresentation. OutputConverter then mapped that to a workflow_action item with status=failed and dropped the exception entirely, so callers got status=completed and error=null even when an executor threw.

- WorkflowSession.cs: add ExecutorFailedEvent case mirroring WorkflowErrorEvent. Honors _includeExceptionDetails.

- OutputConverter.cs: when an update carries both a WorkflowEvent in RawRepresentation and non-empty Contents, fall through to content processing so the unwrapped error (or any future content payload from a workflow event) is actually emitted.

* improve: walk inner exceptions when surfacing ExecutorFailedEvent

DeclarativeActionExecutor wraps inner exceptions in DeclarativeActionException with a generic `Unhandled workflow failure` message, hiding the real cause. Walk InnerException so the response shows the full chain (e.g. the underlying HTTP 400 / auth error).

* Surface declarative SendActivity output as chat content

SendActivityExecutor now emits AgentResponseEvent in addition to
MessageActivityEvent so chat protocols (e.g. AsAIAgent) receive the
formatted activity text. The existing MessageActivityEvent is preserved
for DevUI/observability.

Also extend WorkflowSession.WorkflowOutputEvent handling to accept
AgentResponse payloads, mapping them to their constituent ChatMessages.

* Persist hosted-agent sessions to disk; fix System.LastMessageText

Adds FileSystemAgentSessionStore that writes the serialized AgentSession JSON

(which already embeds the workflow's in-memory checkpoint manager) to a per-

conversation file under /.checkpoints when running in a Foundry hosted env

or {cwd}/.checkpoints locally. Mirrors the python foundry_hosting._responses

FileCheckpointStorage pattern so multi-turn workflow state survives process

restarts without requiring callers to wire up storage themselves.

AddFoundryResponses now defaults to FileSystemAgentSessionStore.CreateDefault()

instead of InMemoryAgentSessionStore; callers can still override via DI.

Also fixes {System.LastMessageText} resolving empty: DeclarativeWorkflowExecutor

.AdvanceAsync was passing the message rehydrated from CreateMessageAsync to

SetLastMessageAsync, but ResponseItem -> ChatMessage round-trip drops the .Text

extension content. Use the original input ChatMessage (which still has the

user-supplied text) and copy the server-assigned MessageId across when present.

* Close multi-modal input parity gaps with python foundry_hosting

InputConverter now mirrors the python _responses.py content handling:

- ComputerScreenshotContent maps to UriContent/HostedFileContent (was dropped).

- Plain TextContent and SummaryTextContent map to MEAI TextContent.

- MessageContentReasoningTextContent maps to MEAI TextReasoningContent.

- input_file with text/* file_data data URIs is decoded inline into

  TextContent with a [File: name] prefix, matching python _convert_file_data

  so {System.LastMessageText} surfaces the file body. Non-text data URIs and

  hosted/url file references preserve filename as AdditionalProperties.

Image/file extraction logic is extracted into shared AppendImageContent and

AppendFileContent helpers used by both the fresh-input and history-replay

switches. Existing 37 InputConverter tests still pass.

* Foundry hosting: round-trip tool-approval (HITL) content as mcp_approval_request/response

Closes the gap where Microsoft.Agents.AI.Foundry.Hosting silently dropped
MEAI ToolApprovalRequestContent/ToolApprovalResponseContent in both
directions. We now serialize them onto the wire as the standard Responses
API mcp_approval_request/mcp_approval_response items with
server_label='agent_framework', and parse the symmetric inbound shapes
back into MEAI content.

Wire format:
- The Responses API only standardizes mcp_approval_* as the approval
  primitive. We declare AF as a virtual MCP server via the server_label
  field, which is honest for AF's server-side tool-call holding pattern.
- The SDK enforces a strict {prefix}_{50hex} wire-id format, so we hash
  the AF RequestId and persist a wireId<->afRequestId mapping in
  AgentSession.StateBag so a later mcp_approval_response can be matched
  back to the originating workflow request.

Coexists with the existing ConsentAwareMcpClientAIFunction flow
(AgentFrameworkResponseHandler.cs) which emits mcp_approval_request from
a side-channel, not via OutputConverter's content switch.

Known follow-up: python (foundry_hosting/_responses.py) has the same
output-side gap (ToolApprovalRequestContent emission). Out of scope here.

Tests: +9 unit tests covering both fresh-input and history-replay shapes,
StateBag mapping resolution, and the non-FunctionCallContent skip path.
Existing 108 converter tests still pass; full suite 370/370.

* Address PR review feedback for hosted-declarative-dotnet

FileSystemAgentSessionStore reliability/scoping:

- Bound Sanitize() stackalloc at 256 chars, fall back to ArrayPool for longer ids so a long conversationId can no longer crash the hosting process with StackOverflowException.

- Use a Guid-suffixed temp file (\{path}.{guid}.tmp\) so concurrent SaveSessionAsync calls on the same conversation can no longer race on the same temp file. Best-effort temp cleanup on failure.

- Bucket session files by agent.Name when set so two keyed agents that happen to share a conversationId no longer overwrite each other's persisted state. Single-agent / unnamed-agent cases keep the original flat layout (Python parity).

DeclarativeWorkflowExecutor chat-protocol routing:

- ConfigureChatProtocolRoutes uses IsAssignableFrom rather than exact type equality so a broader TInput (object, base interfaces) does not have its inherited inputTransform shadowed by handlers we register here.

- HandleChatMessagesAsync / HandleChatMessageArrayAsync now advance through every message in the batch instead of keeping only the trailing one, so multi-message turns and replayed history are no longer silently truncated. AdvanceAsync gains a finalizeTurn flag so only the last message in the batch sends the result.

Tests:

- New FileSystemAgentSessionStoreTests covering constructor, fresh-session fallback for missing/empty files, root-directory creation, save/get round-trip, agent-Name scoping isolation, long conversationId, invalid-character sanitization, and concurrent-save behavior.

- New InputConverterTests covering AppendFileContent: text/* data URI decode (with and without filename prefix), non-text data URI passthrough, malformed data URI fallback, and filename propagation onto UriContent / HostedFileContent.

* Add tests for remaining PR review feedback (C2, D1, E1)

C2: InputConverter — add 9 tests covering SDK content types that previously
had no coverage:
  - SdkTextContent → TextContent (input + output paths)
  - SummaryTextContent → TextContent (input + output paths)
  - MessageContentReasoningTextContent → TextReasoningContent (input + output)
  - ComputerScreenshotContent (HTTP URL → UriContent, data: URI → DataContent,
    output path → UriContent)

D1: OutputConverter — add 2 tests for the WorkflowEvent + Contents fall-through:
  - WorkflowEvent in RawRepresentation with text Contents must flow through
    the content-processing path (text-delta event emitted).
  - WorkflowEvent + ErrorContent must produce a failed event rather than be
    swallowed by the workflow branch.

E1: SendActivityExecutor — extend CaptureActivityAsync to assert that the
executor emits an AgentResponseEvent carrying the activity text with the
correct ExecutorId and ChatRole.Assistant role.

* Defense-in-depth: neutralize dot-segments in Sanitize and cap TryDecodeTextDataUri input size

Addresses claude-opus-4.6 security review on PR #5589:

- FileSystemAgentSessionStore.Sanitize now replaces all-dot segments
  (., .., ...) with underscores so a developer-controlled agent.Name
  cannot escape the root directory on Linux (where Path.GetInvalidFileNameChars
  only contains NUL and '/').

- InputConverter.TryDecodeTextDataUri rejects encoded payloads larger than
  16 MiB before calling Convert.FromBase64String, preventing a single
  oversized data URI from triggering a multi-megabyte allocation.

- Adds unit tests covering both fixes.

* Fix Linux-only failure in SaveSessionAsync_SanitizesInvalidPathCharactersAsync

'?' is in Path.GetInvalidFileNameChars only on Windows, not on Linux/macOS,
so the test failed on Ubuntu in CI. Use Path.GetInvalidFileNameChars()[0]
(skipping NUL) to pick a guaranteed-invalid character for the running OS,
and assert the result no longer contains it.

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

* Address claude-opus-4.6 security/reliability review feedback

WorkflowSession.cs:
- ExecutorFailedEvent handler no longer leaks the internal executor ID
  in error messages. Mirror the WorkflowErrorEvent pattern: surface the
  exception's Message when _includeExceptionDetails is true, fall back
  to the generic 'An error occurred while executing the workflow.' otherwise.
  This also resolves the failing WorkflowHostSmokeTests assertions.

FileSystemAgentSessionStore.cs:
- GetSessionPath no longer has a write side effect. Directory.CreateDirectory
  for the per-agent bucket is now performed only on the SaveSessionAsync
  path, so a read miss on GetSessionAsync no longer leaves an empty
  directory on disk.
- Adds GetSessionAsync_NoExistingFile_DoesNotCreateAgentDirectoryAsync
  to lock in the no-side-effect-on-read contract.

OutputConverterTests.cs:
- Strengthen ConvertUpdatesToEventsAsync_ToolApprovalRequest_NonFunctionToolCall_SkippedAsync
  to assert exactly one event (the terminal ResponseCompletedEvent) so a
  spurious output-item-added/-done leak would now fail the test.

* Address PR review: clean up comments and rename TryParseArguments

- Remove Python-codebase references from C# XML docs and inline comments.
- Drop fix-history comments referring to previously-resolved issues.
- Drop `Defense-in-depth:` prefixes; keep the concrete `what & why`.
- Drop `previously we kept only the trailing message` comment in
  DeclarativeWorkflowExecutor; just describe current loop behavior.
- Rename InputConverter.TryParseArguments to ParseFunctionArgumentsObject
  to make the intent obvious at the call site.

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

* Address PR review: collision-free Sanitize, MAF-style refactors

- FileSystemAgentSessionStore.Sanitize now percent-encodes invalid chars
  (and `%` itself) instead of replacing them with `_`, eliminating
  collisions like `foo/bar` vs `foo_bar` mapping to the same bucket.
  All-dot segments encode every dot so Windows trailing-dot trimming
  cannot reintroduce a navigable name.
- AddFoundryResponses XML doc updated to accurately describe the default
  store root (/.checkpoints when hosted, {cwd}/.checkpoints locally).
- DeclarativeWorkflowExecutor.ConfigureChatProtocolRoutes now uses exact
  type equality instead of IsAssignableFrom so a broad TInput (e.g.
  object) does not skip registering IEnumerable<ChatMessage>, which
  ChatProtocolExtensions.IsChatProtocol requires verbatim.
- SendActivityExecutor uses context.YieldOutputAsync(response) instead
  of manually constructing AgentResponseEvent, so the activity will
  participate in any future OutputFilter coverage.
- WorkflowSession handles AgentResponseEvent in its own switch case,
  avoiding the second typecheck against output.Data.

* fix(workflows): bridge declarative HITL through Foundry hosting via IExternalRequestEnvelope

Introduce a new public interface IExternalRequestEnvelope in
Microsoft.Agents.AI.Workflows that lets the runtime peek through a
declarative-layer envelope without taking a circular reference back into
the declarative package. ExternalInputRequest (declarative) implements
it; ExternalInputResponse is constructed via the request's CreateResponse
factory. WorkflowSession unwraps inner AIContent on the request side and
rewraps the client's ChatMessage reply into an ExternalInputResponse on
the response side. PortableValue cannot deserialize directly into an
interface, so TryGetRequestEnvelope resolves the concrete type via
RequestPortInfo.RequestType (TypeId -> Type.GetType) before casting.

Public WorkflowHarness contract preserved: InvokeFunctionToolExecutor
and WorkflowActionVisitor are unchanged from upstream, so public
InvokeToolWorkflowTest scenarios continue to drive
ExternalInputRequest / ExternalInputResponse directly through the
harness.

AgentFrameworkResponseHandler: skip prior conversation history replay
when an existing session is being resumed (workflow checkpoint already
holds the prior messages).

WorkflowSession: when includeExceptionDetails is opted in, also unwrap
DeclarativeActionException so HITL failures are debuggable.

Roger BarretoandGitHub fb97e93a01 .NET: Add dedicated Foundry.Hosting UnitTest project (#5592)
* Foundry.Hosting.UnitTests: extract project from Foundry.UnitTests

Move all Hosting/* tests, three toolbox TestData JSONs, and the FakeAuthenticationTokenProvider/HttpHandlerAssert/TestDataUtil helpers (trimmed to toolbox getters) into a new Microsoft.Agents.AI.Foundry.Hosting.UnitTests project. Add it to the slnx and grant the new assembly InternalsVisibleTo from Microsoft.Agents.AI.Foundry and Microsoft.Agents.AI.Foundry.Hosting.

* Foundry.Hosting.UnitTests: align namespaces to assembly name

Rename namespaces from Microsoft.Agents.AI.Foundry.UnitTests(.Hosting) to Microsoft.Agents.AI.Foundry.Hosting.UnitTests across all moved tests, the duplicated helpers, and the trimmed TestDataUtil. Also fixes the prior namespace inconsistency in FoundryToolboxTests.

* Foundry.Hosting.UnitTests: split WorkflowIntegrationTests by SUT

Replace the WorkflowIntegrationTests file (an IT-named file inside a UT project) with two SUT-focused files plus a shared test-doubles file:

- AgentFrameworkResponseHandlerWorkflowTests.cs - the 5 handler-driven tests that exercise AgentFrameworkResponseHandler with a real workflow agent.
- OutputConverterWorkflowTests.cs - the 5 OutputConverter tests driven by hand-crafted update sequences mirroring real workflow patterns.
- WorkflowTestAgents.cs - StreamingTextAgent and ThrowingStreamingAgent extracted as internal types used by both files.

* Foundry.UnitTests: trim Hosting-related conditionals and dead testdata

Now that Hosting tests live in their own project:
- drop the Compile Remove guard for the Hosting subfolder,
- drop the .NETCoreApp-only PackageReferences (Azure.AI.AgentServer.Responses, Microsoft.AspNetCore.TestHost, OpenTelemetry, OpenTelemetry.Exporter.InMemory),
- drop the conditional ProjectReference to Microsoft.Agents.AI.Foundry.Hosting,
- delete the three Toolbox JSON files and the matching Toolbox getters in TestDataUtil.

* Foundry.Hosting.UnitTests: drop redundant 'using Microsoft.Agents.AI.Foundry.Hosting'

The new project namespace is Microsoft.Agents.AI.Foundry.Hosting.UnitTests, which already brings the parent Microsoft.Agents.AI.Foundry.Hosting namespace into scope. The explicit using statement is therefore redundant (IDE0005). Caught by 'dotnet format --verify-no-changes' running on Linux against the .NET 10 SDK.

* Foundry.Hosting: drop InternalsVisibleTo to Foundry.UnitTests

The non-hosting Foundry.UnitTests project no longer holds any Hosting tests after the split, so it doesn't need access to internal types in Microsoft.Agents.AI.Foundry.Hosting. Only Microsoft.Agents.AI.Foundry.Hosting.UnitTests needs it.

* Foundry.Hosting: rename DelegatingResponsesClient to UserAgentResponsesClient

Address westey-m's review feedback on PR #5453: `Delegating*` is conventionally reserved for inheritable base classes (mirroring `DelegatingHandler`) where consumers override one or two members. This polyfill is sealed and only injects the User-Agent supplement, so the new name reflects its actual purpose.

Renamed via `git mv` to preserve history:
* `src/Microsoft.Agents.AI.Foundry.Hosting/DelegatingResponsesClient.cs` to `UserAgentResponsesClient.cs`
* `tests/Microsoft.Agents.AI.Foundry.Hosting.UnitTests/DelegatingResponsesClientTests.cs` to `UserAgentResponsesClientTests.cs`

Class, constructor, and all references updated across:
* `src/.../UserAgentResponsesClient.cs` (class + constructor + internal log message)
* `src/.../ServiceCollectionExtensions.cs` (cref + type check + instantiation)
* `src/.../HostedAgentUserAgentPolicy.cs` (cref)
* `tests/Foundry.UnitTests/RequestOptionsExtensionsTests.cs` (comment)
* `tests/Foundry.Hosting.UnitTests/UserAgentResponsesClientTests.cs` (class + cref + instantiations)

* Trying to get UA flowing, no luck yet.

* .NET: Polyfill MEAI OpenAIResponsesChatClient to add hosted-agent User-Agent supplement

When AgentFrameworkResponseHandler resolves an agent (i.e. we are running in a
hosted context), TryApplyUserAgent walks the agent's IChatClient decorator chain
to find MEAI's internal OpenAIResponsesChatClient and reflectively swaps its
inner _responseClient field with a DelegatingResponsesClient wrapper. The
wrapper overrides the public-virtual protocol methods to add a per-call
HostedAgentUserAgentPolicy to the RequestOptions and delegate to the inner
ResponsesClient. The OpenAI SDK's internal streaming overloads bottom out in
calls to the public-virtual non-streaming overloads via virtual dispatch on
this, so streaming is covered without overriding any non-virtual member.

The wrapper accepts any ResponsesClient-derived inner — both the Foundry
ProjectResponsesClient and the native OpenAI ResponsesClient — and preserves
the inner client's full pipeline (Transport, RetryPolicy, NetworkTimeout,
OrganizationId / ProjectId / UserAgentApplicationId, custom policies).

- Add DelegatingResponsesClient + HostedAgentUserAgentPolicy in Microsoft.Agents.AI.Foundry.Hosting.
- Add TryApplyUserAgent next to ApplyOpenTelemetry in FoundryHostingExtensions; wire it into AgentFrameworkResponseHandler.GetAgent for both keyed and default-agent paths.
- Drop earlier-iteration dead code: AddHostedAgentTelemetry extension, HostedUserAgentPolicy class, HostedAgentContext.cs, and the never-called ToRequestOptions helper.
- Revert RequestOptionsExtensions.MeaiUserAgentPolicy to MEAI-only (the supplement is now injected by the polyfill).
- Revert unrelated whitespace change in Agent_Step25_ToolboxServerSideTools sample.
- Tests cover streaming AND non-streaming, retry policy preservation, OrganizationId/ProjectId/UserAgentApplicationId pass-through, idempotency, native OpenAI ResponsesClient, and reflection guards for MEAI/OpenAI shape drift.

* .NET: Address review feedback on hosted-agent User-Agent polyfill

- TryApplyUserAgent: replace silent null-return with ArgumentNullException to match the codebase's convention.
- Add idempotency test (TryApplyUserAgent_CalledTwiceOnSameAgent_DoesNotDoubleWrap) — runs the polyfill twice on the same agent and asserts the wire UA contains exactly one foundry-hosting segment, proving the 'current is DelegatingResponsesClient' guard prevents nested wrapping.
- Add retry-double-append test (Polyfill_RetryWithinCall_DoesNotDuplicateSupplementInUserAgent) — exercises the HostedAgentUserAgentPolicy Contains-guard via a custom retry policy that re-runs the inner pipeline on the same message.
- Replace TryApplyUserAgent_NullAgent_ReturnsNullWithoutThrowing with TryApplyUserAgent_NullAgent_ThrowsArgumentNullException to match the new contract.

* .NET: Drop null check from TryApplyUserAgent and its now-redundant test

The two call sites in AgentFrameworkResponseHandler.GetAgent already null-check the agent before invoking TryApplyUserAgent, so the defensive ArgumentNullException is unreachable. Remove it and the corresponding test.

* .NET: Remove unused Microsoft.Shared.Diagnostics import in ServiceCollectionExtensions

The Throw.IfNull helper from this namespace was used by the now-removed null check in TryApplyUserAgent. Drop the unused import to satisfy IDE0005 in CI's full-project dotnet format run.

* Add streaming edge-case tests for A2AAgentHandler

Add two tests covering gaps in the streaming path:

- ExecuteAsync_Streaming_WhenNoUpdates_EnqueuesNoMessagesAndSavesSessionAsync:
  Verifies that when RunStreamingAsync yields an empty async enumerable,
  no messages are enqueued and only SaveSessionAsync runs.

- ExecuteAsync_Streaming_CancellationTokenIsPropagatedToRunStreamingAsyncAsync:
  Verifies that the CancellationToken from ExecuteAsync is propagated
  through to the inner agent's RunCoreStreamingAsync call.

* 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.

* Add Azure AI Foundry Responses hosting adapter

Implement Microsoft.Agents.AI.Hosting.AzureAIResponses to host agent-framework
AIAgents and workflows within Azure Foundry as hosted agents via the
Azure.AI.AgentServer.Responses SDK.

- AgentFrameworkResponseHandler: bridges ResponseHandler to AIAgent execution
- InputConverter: converts Responses API inputs/history to MEAI ChatMessage
- OutputConverter: converts agent response updates to SSE event stream
- ServiceCollectionExtensions: DI registration helpers
- 336 unit tests across net8.0/net9.0/net10.0 (112 per TFM)
- ResponseStreamValidator: SSE protocol validation tool for samples
- FoundryResponsesHosting sample app

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

* 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.

* Register AgentSessionStore in test DI setups

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

* 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.

Jacob AlberandGitHub d5777bc546 fix: Duplicate CallIds cause Handoff Message Filtering to fail (#5359)
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.

- 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

* 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.

* Rename AzureAI→Foundry: move eval files, update references

- Move FoundryEvals.cs and FoundryEvalConverter.cs from
  Microsoft.Agents.AI.AzureAI to Microsoft.Agents.AI.Foundry
- Update namespace from AzureAI to Foundry in both files
- Add explicit usings required by Foundry project (no implicit usings)
- Move FoundryEvalConverter tests to Foundry.UnitTests project
  (avoids ReplacingRedactor type conflict from dual project refs)
- Update all sample csproj references and using statements
- Remove Foundry project reference from AI UnitTests

* PR review round 4: wire up tool extraction, remove eval cache, fix null safety

- BuildEvalItem: extract tools from agent via GetService<ChatOptions>() into EvalItem.Tools (Python parity)
- FoundryEvals: remove eval ID cache - each call creates fresh definition (matches Python behavior)
- FoundryEvals: replace null-forgiving operators with descriptive InvalidOperationException
- MixedProviders sample: remove unnecessary explicit PackageReferences (transitively provided)
- FoundryEvalConverter: document that tool results take precedence over text content
- Add LocalEvaluator zero-checks test documenting 0 metrics = failed behavior

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

* Python-dotnet parity: 9 feature gaps filled

New checks:
- ToolCallArgsMatch() — verify tool call names + argument subset match
- ToolCalledCheck(ToolCalledMode.Any, ...) — match any of the specified tools
- ToolCalledMode enum (All/Any)

FoundryEvals enhancements:
- Default evaluators now [Relevance, Coherence, TaskAdherence] (was Relevance, Coherence)
- Auto-add ToolCallAccuracy when items have tool definitions
- EvaluateTracesAsync — evaluate by response_ids, trace_ids, or agent_id
- EvaluateFoundryTargetAsync — evaluate deployed Foundry targets

Result type enrichment:
- AgentEvaluationResults: added Status, Error, PerEvaluator, DetailedItems
- New EvalItemResult/EvalScoreResult/PerEvaluatorResult types
- FoundryEvals populates all new fields from API responses

Workflow fix:
- Skip internal executors (_*, input-conversation, end-conversation, end)

Tests: 8 new tests covering ToolCallArgsMatch, ToolCalledMode.Any, internal executor filtering

* Add MeaiEvaluatorAdapter and PerTurnItems edge case tests

- 3 tests for MeaiEvaluatorAdapter: query message forwarding, synthetic
  response fallback, multiple items aggregation
- 3 tests for EvalItem.PerTurnItems: empty conversation, no user messages,
  system+assistant only
- StubEvaluator and StubChatClient test helpers

* Blocking link check for outdated package in DevUI.

* Replace Dictionary<string, object> payloads with typed wire models

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.

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.

Add discovery-time validation in AgentClassSkill.DiscoverResources() to

- Reject indexer properties (getter has parameters)
- Reject methods with parameters other than IServiceProvider or
  CancellationToken

- Add _Rapi_ prefix to non-versioned (Responses API) tests
- Add _Versioned_ prefix to versioned agent tests where needed
- Fix RAPI tests: assert GetService<AIProjectClient>() is null
- Fix Versioned tests: assert IsType<FoundryAgent> and
  GetService<AIProjectClient>() returns the client instance
- Fix UserAgent header tests: proper HTTP handler routing
- Fix ChatClient_UsesDefaultConversationIdAsync test setup
- All 153 unit tests pass with 0 failures

ca02146ee4 .NET: BugFix #3433 ChatClientAgent streaming responses missing messageid (#4615)
* Changes

* Fix ChatClientAgent streaming responses missing MessageId

Generate fallback MessageId in ChatClientAgent.RunCoreStreamingAsync when
the underlying LLM provider does not set ChatResponseUpdate.MessageId.
Without a MessageId the AGUI converter's null==null check silently drops
all text content, causing CopilotKit Zod validation errors.

Changes:
- ChatClientAgent: generate msg_{Guid} fallback via ??= in streaming loop
- AgentResponseExtensions: sync wrapper MessageId back to RawRepresentation
  in AsChatResponseUpdate() so downstream consumers see the value
- Add unit tests for both fixes and AGUI streaming MessageId scenarios

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

* Address PR #4615 review comments

- Fix MessageId seeding: use first-seen provider MessageId (or generate
  fallback) and apply consistently to all chunks in the stream, preventing
  message splitting when providers set MessageId only on the first chunk
- Add test for mixed MessageId scenario (first chunk only)
- Fix skipped TextStreaming test: assert Empty (not NotEmpty) to match
  actual null==null behavior
- Fix skipped ToolCalls test: assert empty ParentMessageId to match
  actual empty-string passthrough behavior

* Handle empty MessageId in AsChatResponseUpdate sync

Treat empty/whitespace MessageId the same as null when syncing from
the AgentResponseUpdate wrapper back to RawRepresentation. Providers
that return empty string MessageId (e.g. tool call responses) now get
the wrapper value recovered correctly.

Add test for empty string MessageId recovery scenario.

* Move MessageId fallback generation to AGUI layer

Move fallback MessageId generation from ChatClientAgent to
AsAGUIEventStreamAsync, addressing the architectural concern that
MessageId is nullable in the AIAgent abstraction and the requirement
for non-null values is specific to the AGUI protocol.

The AGUI layer now generates a fallback MessageId for null or
empty/whitespace values, covering all agent types (not just
ChatClientAgent) including external implementations.

Changes:
- Revert MessageId generation from ChatClientAgent.RunCoreStreamingAsync
- Add fallback MessageId generation in AsAGUIEventStreamAsync for
  null/empty MessageId values (handles both null and whitespace)
- Unskip and update AGUI tests to verify fallback generation
- Update ChatClientAgent tests to reflect passthrough behavior

* Revert AsChatResponseUpdate MessageId sync-back

Remove the MessageId sync-back logic from AsChatResponseUpdate() as it
is no longer needed. With fallback generation moved to the AGUI layer,
the abstraction layer should not mutate the RawRepresentation object.

Revert to the original passthrough behavior for AsChatResponseUpdate()
and update tests accordingly.
