  • .NET: BREAKING: Unify AgentResponse[Update] events as WorkflowOutputEvents (#3441) 
    * Rename WorkflowOutputEvent.SourceId to ExecutorId for Python consistency

- Rename SourceId property to ExecutorId in WorkflowOutputEvent
- Add [Obsolete] SourceId property for backward compatibility
- Update all test usages to use ExecutorId

Resolves part of #2938

* Unify AgentResponse events with WorkflowOutputEvent (#2938)

- Change AgentResponseEvent and AgentResponseUpdateEvent to inherit from
  WorkflowOutputEvent instead of ExecutorEvent
- Update AIAgentHostExecutor and HandoffAgentExecutor to use YieldOutputAsync()
  instead of AddEventAsync() for agent outputs
- Add special-casing in InProcessRunnerContext.YieldOutputAsync() to create
  specific event types for AgentResponse and AgentResponseUpdate, bypassing
  OutputFilter for backwards compatibility
- Update TestRunContext and TestWorkflowContext with same special-casing
- Add regression tests in AgentEventsTests

* refactor: Seal AgentResponse events

  • .NET: Workflow telemetry opt in (#3467) 
    * feat(workflows): Make telemetry opt-in via WithOpenTelemetry()

- Add WorkflowTelemetryOptions class with EnableSensitiveData property
- Add WorkflowTelemetryContext to manage ActivitySource lifecycle
- Add WithOpenTelemetry() extension method on WorkflowBuilder
- Update all workflow components to use telemetry context:
  - WorkflowBuilder, Workflow, Executor
  - InProcessRunnerContext, InProcessRunner
  - LockstepRunEventStream, StreamingRunEventStream
  - All edge runners (Direct, FanIn, FanOut, Response)
- Telemetry is now disabled by default
- Users must call WithOpenTelemetry() to enable spans/activities

BREAKING CHANGE: Workflow telemetry is now opt-in. Users who relied on
automatic telemetry must add .WithOpenTelemetry() to their workflow builder.

* refactor: Pass telemetry context as parameter instead of via interface

- Remove IWorkflowContextWithTelemetry interface
- Add internal ExecuteAsync overload that accepts WorkflowTelemetryContext
- Public ExecuteAsync delegates with WorkflowTelemetryContext.Disabled
- InProcessRunner passes TelemetryContext when calling ExecuteAsync
- BoundContext now implements IWorkflowContext (not the removed interface)

* Add optional ActivitySource parameter to WithOpenTelemetry

Allow users to provide their own ActivitySource when enabling telemetry,
giving them better control over the ActivitySource lifecycle. When not
provided, the framework creates one internally (existing behavior).

Changes:
- Add optional activitySource parameter to WithOpenTelemetry() extension
- Update WorkflowTelemetryContext to accept external ActivitySource
- Add unit test for user-provided ActivitySource scenario

* Add component-level telemetry control with disable flags

Allow users to selectively disable specific activity types via
WorkflowTelemetryOptions. All activities are enabled by default.

New disable flags:
- DisableWorkflowBuild: Disables workflow.build activities
- DisableWorkflowRun: Disables workflow_invoke activities
- DisableExecutorProcess: Disables executor.process activities
- DisableEdgeGroupProcess: Disables edge_group.process activities
- DisableMessageSend: Disables message.send activities

Added helper methods to WorkflowTelemetryContext for each activity type
and updated all activity creation sites to use them.

* Implement EnableSensitiveData to log executor input/output

When EnableSensitiveData is true in WorkflowTelemetryOptions, executor
input and output are logged as JSON-serialized attributes in the
executor.process activity.

New activity tags:
- executor.input: JSON serialized input message
- executor.output: JSON serialized output result (non-void only)

Added suppression attributes for AOT/trimming warnings since this is
an opt-in feature for debugging/diagnostics.

* Refactor activity start methods to centralize tagging logic

Move tagging logic into WorkflowTelemetryContext methods:
- StartExecutorProcessActivity now accepts executorId, executorType,
  messageType, and message; sets all tags including executor.input
  when EnableSensitiveData is true
- Added SetExecutorOutput method to set executor.output after execution
- StartMessageSendActivity now accepts sourceId, targetId, and message;
  sets all tags including message.content when EnableSensitiveData is true

Simplified Executor.cs and InProcessRunnerContext.cs by removing
inline tagging code. Added message.content tag constant.

* Revert Python changes

* Update samples and code cleanup

* Fix file formatting

* Add comment

* Add telemetry configuration to declarative workflow

* Remove delays in tests

  • fix: Subworkflows do not work well with HostAsAgent (#3240) 
    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)

  • fix: .NET: Concurrency Support for Orchestrations (#1689) 
    Concurrent run support was recently added to workflows, but Orchestrations did not fully update to support it. A few executors were missing Cross-Run Shareable annotations, and the ConcurrentEnd executor needed to be factory-instantiated.

This also ports the fix for #1613 from #1637, to avoid waiting on that PR.

  • fix: InMemoryCheckpointManager is not JSON serializable (#1639) 
    Checkpointing is used by the WorkflowHostAgent to be able to support resume from a provided thread. When a CheckpointManager is not specified, we use the InMemoryCheckpointManager and serialize its state into the thread's Serialize()ed JsonElement.

At some point InMemoryCheckpointManager became not serializable, breaking this behaviour. This change restores serializability, and adds a test.

  • [BREAKING] .NET: Workflow Off-Thread Execution Mode (#1233) 
    * 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

  • feat: Add name and description support to workflows (#1183) 
    Add optional name and description fields to workflows in both Python and .NET implementations, matching the existing agent API pattern.

Python changes:
- Add name/description parameters to WorkflowBuilder.__init__
- Add name/description attributes to Workflow class
- Include name/description in to_dict() serialization
- Add WORKFLOW_NAME and WORKFLOW_DESCRIPTION OTEL attributes
- Add tests in test_serialization.py and test_workflow_observability.py

.NET changes:
- Add Name and Description properties to Workflow and Workflow<T>
- Add WithName() and WithDescription() fluent methods to WorkflowBuilder
- Add WorkflowName and WorkflowDescription OTEL tags
- Add test in WorkflowBuilderSmokeTests.cs

This enables applications like DevUI to display human-readable workflow names (e.g., 'Data Processing Pipeline') instead of auto-generated UUIDs (e.g., 'Workflow 50fdd917').

Fixes: #1181
