There is a timeout-wait for messages in the inner loop driving the running of the workflow. When it gets cleared, an attempt to run a superstep is made. Currently we set the state to running as soon as the wait clears, even if we have no work to do, and clear it upon discovering this.
The fix is to only set the Running state when actual Workflow execution is happening when running Super-Steps, and not until the loop confirms there is work to do.
A broader-term fix would be to remove the Semaphore and timeout-wait in it, since it is working around the inability to atomicaly insert and release the Semaphore,
* [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
Track the last CheckpointInfo in InProcessRunner so that newly created
checkpoints reference their parent. When resuming from a checkpoint,
the resumed-from checkpoint becomes the parent of the next checkpoint.
Adds tests verifying:
- First checkpoint has null parent
- Subsequent checkpoints chain parents correctly
- Checkpoint after resume references the resumed-from checkpoint

* Fixes and expalins send/yield type registration in FunctionExecutor

* fix: Add missing SendsMesage declaration to InvokeAzureAgentExecutor
* Fix FoundryAgents_Step15_ComputerUse sample for Azure Agents API
The Azure Agents API rejects previous_response_id alongside computer_call_output
items, unlike the vanilla OpenAI Responses API. This fix:
- Send all prior response output items (reasoning, computer_call, etc.) as input
items in follow-up calls so the API has full conversation context
- Create a fresh session per call to avoid ConversationId/previous_response_id
- Use currentCallId instead of initialCallId for computer_call_output
- Clear ContinuationToken after polling to prevent stale tokens
- Remove unused initialCallId tracking variable

* Add note about agent-targeted red teaming limitations in README
The .NET RedTeam API currently only supports model deployment targets
via AzureOpenAIModelConfiguration. Agent-targeted red teaming with
AzureAIAgentTarget is documented in concept docs but not yet available
in the SDK's RedTeam constructor. Results appear in classic portal view.

* Add classic Foundry disclaimer to red teaming sample README
Clarify that this sample uses the classic Azure AI Foundry red teaming
API (/redTeams/runs). The new Foundry portal uses a separate evaluation-
based API not yet available in the .NET SDK. AzureAIAgentTarget exists
in the SDK but is consumed by the Evaluation Taxonomy API, not RedTeam.

* Address PR review comments on Step02 SelfReflection
- Pass full prompt (with context) to evaluator messages instead of just
the question, so evaluator input matches what the agent received
- Include previous response text in self-reflection refinement prompt
so the LLM can meaningfully improve its answer across iterations
- Inline CreateKnowledgeAgent helper (single use, single statement)
- Add comment clarifying why RunCombinedQualityAndSafetyEvaluation
intentionally passes only the question (no context)
