* 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.

* .NET: Fixing issue where OpenTelemetry span is never exported in .NET in-process workflow execution (#4196)
* 1. Add reproduction test for issue #4155: workflow.run Activity never stopped in streaming OffThread path
The WorkflowRunActivity_IsStopped_Streaming_OffThread test demonstrates that
the workflow.run OpenTelemetry Activity created in StreamingRunEventStream.RunLoopAsync
is started but never stopped when using the OffThread/Default streaming execution.
The background run loop keeps running after event consumption completes, so the
using Activity? declaration never disposes until explicit StopAsync() is called.

2. Fix workflow.run Activity never stopped in streaming OffThread execution (#4155)
The workflow.run OpenTelemetry Activity in StreamingRunEventStream.RunLoopAsync
was scoped to the method lifetime via 'using'. Since the run loop only exits on
cancellation, the Activity was never stopped/exported until explicit disposal.
Fix: Remove 'using' and explicitly dispose the Activity when the workflow reaches
Idle status (all supersteps complete). A safety-net disposal in the finally block
handles cancellation and error paths.

* Add root-level workflow.session activity spanning run loop lifetime\n\nImplements two-level telemetry hierarchy per PR feedback from lokitoth:\n- workflow.session: spans the entire run loop / stream lifetime\n- workflow_invoke: per input-to-halt cycle, nested within the session\n\nThis ensures the session activity stays open across multiple turns,\nwhile individual run activities are created and disposed per cycle.\n\nAlso fixes linkedSource CancellationTokenSource disposal leak in\nStreamingRunEventStream (added using declaration)."
* Address Copilot review: fix Activity/CTS disposal, rename activity, add error tag\n\n1.

* Fix flaky test: prevent spurious workflow_invoke Activity on timeout wake-up
The StreamingRunEventStream run loop uses a 1-second timeout on
WaitForInputAsync. When the timeout fires before the consumer calls
StopAsync, the loop would create a spurious workflow_invoke Activity
even though no actual input was provided. This caused the
WorkflowRunActivity_IsStopped_Streaming_OffThread_MultiTurnAsync test
to intermittently fail (expecting 2 activities but finding 3).
Fix: guard the loop body with a HasUnprocessedMessages check. On
timeout wake-ups with no work, the loop waits again without creating
an activity or changing the run status.

* Fix epoch race condition causing unit tests to hang on net10.0 and net472
The HasUnprocessedMessages guard (previous commit) correctly prevents
spurious workflow_invoke Activity creation on timeout wake-ups, but
exposed a latent race in the epoch-based signal filtering.
The race: when the run loop processes messages quickly and calls
Interlocked.Increment(ref _completionEpoch) before the consumer calls
TakeEventStreamAsync, the consumer reads the already-incremented epoch
and sets myEpoch = epoch + 1. This causes the consumer to skip the
valid InternalHaltSignal (its epoch < myEpoch) and block forever
waiting for a signal that will never arrive (since the guard prevents
spurious signal generation).
Fix: read _completionEpoch without +1. The +1 was originally needed to
filter stale signals from timeout-driven spurious loop iterations, but
those no longer exist thanks to the HasUnprocessedMessages guard.

This reverts commit 6ce7f01be8.

This reverts commit 98963e17f2.
* Skip hanging multi-turn declarative integration tests
The ValidateMultiTurnAsync tests (ConfirmInput.yaml, RequestExternalInput.yaml)
hang indefinitely in CI, blocking the merge queue. The hang is SDK-independent
(reproduces with both Azure.AI.Projects 1.2.0-beta.5 and 2.0.0-beta.1) and
is a pre-existing issue in the declarative workflow multi-turn test logic.

* refactor: Normalize Run/RunStreaming with AIAgent
* refactor: Clarify Session vs. Run -level concepts
* Rename RunId to SessionId to better match Run/Session terminology in AIAgent
* [BREAKING]: Will break existing checkpointed sessions in CosmosDb due to field rename
* refactor: Rename and simplify interface around getting typed data out of ExternalRequest/Response
* Also adds hints around using value types in PortableValue
* refactor: Rename AddFanInEdge to AddFanInBarrierEdge
This will prevent a breaking change later when we introduce a programmable FanIn edge, analogous to the FanOut edge's EdgeSelector.
The goal, in the long run is to support a number of different FanIn scenarios, with naive FanIn (no barrier) by default, similar to FanOut.
* refactor: AsAgent(this Workflow, ...) => AsAIAgent(...)

* [BREAKING] refactor: Decouple Checkpointing and Execution APIs
With this change, Checkpointing becomes an property of an IWorkflowExecutionEnvironment. This lets environments that are tightly-coupled to their CheckpointManager avoid needing to present APIs that would not work (e.g. taking in an InMemory CheckpointManager for Durable Tasks, for example)
* refactor: Normalize IsCheckpointingEnabled naming
* Initial Implementation of InvokeFunctionTool
* Added unit test for InvokeFunctionTool executor.
* Implemented unit and integration tests for InvokeFunctionTool.

Subworkflows run into issues with Checkpointing and the Chat Protocol:
* The concurrency rework made subtle changes in behaviour that introduced a hang when using subworkflows with ChatProtocol and streaming execution.
* The ResetAsync() implementation in WorkflowHostExecutor was improperly resetting the joinContext - this was happening on restore checkpoint _after_ the join context was attached when
* Subworkflows cannot be used as the start node when hosted AsAgent due to inability to treat Catch-All as a Chat Protocol
* Subworkflow ownership issue when used in non-concurrent mode after finishing a run
Also fixes:
* When ChatMessages are output by executors that are not agents, there is no corresponding AgentResponseUpdate/AgentResponse event
Breaking Changes
* [BREAKING CHANGE] It is possible to provide the wrong RunId when resuming from CheckpointInfo (even though the data already exists on CheckpointInfo)
* Upgrade to .NET 10
- Require .NET 10 SDK
- Include net10.0 assets in all assemblies
- Move net9.0-only targets to net10.0
- Update LangVersion to latest
- Remove complicated distinctions between debug target TFMs and release target TFMs
- Remove unnecessary package dependencies when built into netcoreapp
- Clean up some ifdefs
- Clean up some analyzer warnings
* Fix CI
* Updates to async run loop.
* fix: Workflow Onwership can be release by nonowner
* fix: Incorrect handling of blockOnPending in StreamingRun
Depending on whether we are running in streaming on non-streaming mode, we may be using the StreamingRun in different ways. Unfortunately, the only place we can really know what is the actual state of execution is in the RunEventStream implementations.
This resulted in blocking where blocking was unneeded and occasionally not-blocking when blocking was needed.
The fix is to move the logic of handling this blocking into RunEventStream implementations.
* fix: Fix cleanup on error and end run
This ensures we clean up the background resources correctly.
* fix: Ensure we let the run loop proceed when shutting down
* fix: Add timeout for Input Waiting
* fix: Make the samples properly clean up `Run`s and `StreamingRun`s
* fix: Simplify Declarative Workflow Run disposal pattern
* Also fixes missing .Disposal() in Integration tests

We shouldn't be shipping any more dependencies on this package, as it's becoming legacy, replaced by System.Linq.AsyncEnumerable.
We'll eventually want to replace it with System.Linq.AsyncEnumerable in all tests/samples, too, but that's hard to do until SK updates to use S.L.AsyncEnumerable once its 10.0.0 version is released. I did remove the package reference from tests/samples where it's not needed.
