fix: RunState is sometimes Running when it should be Idle

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,

Python: [BREAKING] Redesign Python exception hierarchy (#4082 )

* [BREAKING] Redesign Python exception hierarchy

Replace the flat ServiceException family with domain-scoped branches:
- AgentException (with InvalidAuth, InvalidRequest, InvalidResponse, ContentFilter)
- ChatClientException (same consistent suberrors)
- IntegrationException (same + InitializationError)
- WorkflowException (Runner, Convergence, Checkpoint, Validation, Action, Declarative)
- ContentError (AdditionItemMismatch)
- ToolException / ToolExecutionException (unchanged)
- MiddlewareException / MiddlewareTermination (unchanged)

Key changes:
- All Service* exceptions removed (ServiceException, ServiceInitializationError, etc.)
- AgentExecutionException split into AgentInvalidRequest/ResponseException
- AgentInvocationError removed, split into AgentInvalidRequest/ResponseException
- Workflow exceptions moved from _workflows/_exceptions.py into main exceptions.py
- _workflows/__init__.py emptied; main __init__.py imports directly from submodules
- Purview exceptions re-parented under IntegrationException hierarchy
- Init validation errors use built-in ValueError/TypeError instead of custom exceptions
- CODING_STANDARD.md updated with hierarchy design and rationale

Fixes microsoft/agent-framework#3410

* Clarify ToolException vs ToolExecutionException docstrings

ToolException: base class for all tool-related exceptions (preconditions,
connection/init failures).
ToolExecutionException: runtime call failures (tool call failed, reconnect
failed, MCP errors).

* Fix remaining stale imports from agent_framework._workflows

- azurefunctions: _context.py, _app.py, _serialization.py, test_func_utils.py
  used 'from agent_framework._workflows import X' which broke after
  emptying _workflows/__init__.py; changed to direct submodule imports
- azure-ai-search: test still referenced ServiceInitializationError;
  updated to ValueError to match production code

[BREAKING] .NET: Decouple Checkpointing from Run/StreamAsync APIs (#4037 )

* [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

Unify Azure credential handling across all Python packages (#4088 )

Replace ad_token, ad_token_provider, and get_entra_auth_token with a
unified credential parameter across all Azure-related packages.

Core changes:
- Add AzureCredentialTypes (TokenCredential | AsyncTokenCredential) and
  AzureTokenProvider (Callable[[], str | Awaitable[str]]) type aliases
- Add resolve_credential_to_token_provider() using azure.identity's
  get_bearer_token_provider for automatic token caching/refresh
- Update AzureOpenAIChatClient, AzureOpenAIResponsesClient, and
  AzureOpenAIAssistantsClient to accept credential: AzureCredentialTypes |
  AzureTokenProvider
- Remove ad_token, ad_token_provider params and get_entra_auth_token helpers

Package updates:
- azure-ai: Accept AzureCredentialTypes on AzureAIClient,
  AzureAIAgentClient, AzureAIProjectAgentProvider, AzureAIAgentsProvider
- azure-ai-search: Accept AzureCredentialTypes on
  AzureAISearchContextProvider
- purview: Accept AzureCredentialTypes | AzureTokenProvider on
  PurviewClient, PurviewPolicyMiddleware, PurviewChatPolicyMiddleware

Fixes #3449
Fixes #3500

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

.NET: Fix FoundryAgents_Step15_ComputerUse sample for Azure Agents API (#3989 )

* 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

.NET: Add Foundry Evaluation samples (Safety + Quality) (#3697 )

* Initial plan

* Add Foundry evaluation samples for Red Teaming and Self-Reflection

Co-authored-by: rogerbarreto <19890735+rogerbarreto@users.noreply.github.com>

* Refactor evaluation samples with real implementations in local functions

Co-authored-by: rogerbarreto <19890735+rogerbarreto@users.noreply.github.com>

* Uncomment function signatures and bodies, keep only invocations commented

Co-authored-by: rogerbarreto <19890735+rogerbarreto@users.noreply.github.com>

* Update Foundry evaluation samples with observability support

* Restructure evaluation samples to follow FoundryAgents naming convention

- Rename Evaluation/Evaluation_StepXX to FoundryAgents_Evaluations_StepXX
- Add evaluation projects to slnx
- Fix var usage, apply dotnet format, use DefaultAzureCredential
- Add try/finally for agent cleanup
- Fix evaluator deployment name separation in Step02
- Update README references

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

* Rewrite Step01 to use Azure.AI.Projects RedTeam API and address review comments

- Replace safety evaluator sample with actual Red Teaming using AIProjectClient.RedTeams
- Use AttackStrategy (Easy, Moderate, Jailbreak) and RiskCategory from Azure.AI.Projects
- Remove Microsoft.Extensions.AI.Evaluation.Safety dependency from Step01
- Add DefaultAzureCredential warning comments to Step02
- Remove unused bestResponse variable in Step02
- Add session isolation comments in self-reflection loop
- Fix stale directory references in READMEs
- Fix misleading evaluation overview link in main README

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

* 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.

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

* 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.

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

* 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)

Python: improve .env handling and observability samples (#4032 )

* Python: improve .env precedence and observability samples

- Switch load_settings to explicit precedence: overrides -> explicit .env -> environment -> defaults\n- Raise when env_file_path is provided but missing\n- Update settings docs and tests for new behavior\n- Refresh observability samples and README guidance for env loading options\n\nCloses #3864\n\nCo-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

* fixed some imports

* Fix load_settings CI regressions

Allow explicit env_file_path values that exist but are not regular files (for example /dev/null) by checking path existence before dotenv parsing, and restore a dict accumulator with typed return cast to satisfy mypy.

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

* Avoid implicit dotenv in observability

Only load dotenv in observability helpers when env_file_path is explicitly provided, and remove test os.devnull workarounds that are no longer necessary.

Python: Fix Azure AI sample errors (#4021 )

* Python: Fix Azure AI sample errors

- azure_ai_with_application_endpoint: Add missing name to Agent constructor
- azure_ai_with_file_search: Fix resource path (parents[2] -> parents[3])
- azure_ai_with_openapi: Fix resource path (parents[2] -> parents[3])
- azure_ai_with_session: Use get_agent/get_session to reuse existing agent
  version and preserve conversation context across agent instances

* Python: Fix resource paths in azure_ai_agent samples

- azure_ai_with_file_search: Fix path to employees.pdf (parent.parent -> parents[3]/shared)
- azure_ai_with_openapi_tools: Fix path to weather.json/countries.json (parents[2] -> parents[3])

* fix V1 SDK hosted tools (FileSearchTool, etc.) silently dropped during agent creation

* fix: V2 file search sample uses correct SDK (AIProjectClient instead of AgentsClient)

The azure_ai/azure_ai_with_file_search.py sample incorrectly used the V1
AgentsClient for file/vector store operations. Replaced with V2 pattern:
AIProjectClient + get_openai_client() for file upload and vector store
management, matching the official Azure AI Projects SDK samples.

* fix: use context manager for file open in V2 file search sample

Python: Fixed middleware and multimodal input samples (#4022 )

* Fix streaming branch in weather override middleware sample

The streaming branch of weather_override_middleware only prefixed the
original weather data via a transform hook instead of replacing the
content with the 'perfect weather' override like the non-streaming
branch does. Replace with a new ResponseStream that yields the override
content as ChatResponseUpdate chunks.

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

* Fixed exception handling middleware sample

* Fixed runtime context delegation middleware example

* Fixed multimodal input examples
