* .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. LockstepRunEventStream: Remove 'using' from Activity in async iterator\n and manually dispose in finally block (fixes#4155 pattern). Also dispose\n linkedSource CTS in finally to prevent leak.\n2. Tags.cs: Add ErrorMessage (\"error.message\") tag for runtime errors,\n distinct from BuildErrorMessage (\"build.error.message\").\n3. ActivityNames: Rename WorkflowRun from \"workflow_invoke\" to \"workflow.run\"\n for cross-language consistency.\n4. WorkflowTelemetryContext: Fix XML doc to say \"outer/parent span\" instead\n of \"root-level span\".\n5. ObservabilityTests: Assert WorkflowSession absence when DisableWorkflowRun\n is true.\n6. WorkflowRunActivityStopTests: Fix streaming test race by disposing\n StreamingRun before asserting activities are stopped.\n7. StreamingRunEventStream/LockstepRunEventStream: Use Tags.ErrorMessage\n instead of Tags.BuildErrorMessage for runtime error events."
* Review fixes: revert workflow_invoke rename, use 'using' for linkedSource, move SessionStarted earlier\n\n- Revert ActivityNames.WorkflowRun back to \"workflow_invoke\" (OTEL semantic convention contract)\n- Use 'using' declaration for linkedSource CTS in LockstepRunEventStream (no timing sensitivity)\n- Move SessionStarted event before WaitForInputAsync in StreamingRunEventStream to match Lockstep behavior"
* Improve naming and comments in WorkflowRunActivityStopTests"
* Prevent session Activity.Current leak in lockstep mode, add nesting test
Save and restore Activity.Current in LockstepRunEventStream.Start() so the
session activity doesn't leak into caller code via AsyncLocal. Re-establish
Activity.Current = sessionActivity before creating the run activity in
TakeEventStreamAsync to preserve parent-child nesting.
Add test verifying app activities after RunAsync are not parented under the
session, and that the workflow_invoke activity nests under the session."
* Fix stale XML doc: WorkflowRun -> WorkflowInvoke in ObservabilityTests

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

is a pre-existing issue in the declarative workflow multi-turn test logic.

This will prevent a breaking change later when we introduce a programmable FanIn edge, analogous to the FanOut edge's EdgeSelector.

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.
