  • .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

  • .NET: Fix JSON arrays of objects parsed as empty records when no schema is defined (#4199)
    * fix: use HasSchema check in DetermineElementType to prevent empty records
    
    When parsing JSON arrays containing objects without a predefined schema,
    `DetermineElementType()` was creating a `VariableType` with an empty
    (non-null) schema via `targetType.Schema?.Select(...) ?? []`. This caused
    `ParseRecord` to take the schema-based parsing path, iterating over zero
    schema fields and silently discarding all JSON properties.
    
    The fix checks `targetType.HasSchema` and falls back to
    `VariableType.RecordType` (which has `Schema = null`) when no schema is
    defined, ensuring `ParseRecord` takes the dynamic `ParseValues()` path
    that preserves all JSON properties.
    
    Closes #4195
    
    * test: add regression tests for schema-less JSON array-of-objects parsing (#4195)
    
    Add two regression tests to JsonDocumentExtensionsTests:
    
    1. ParseRecord_ObjectWithArrayOfObjects_NoSchema_PreservesNestedProperties
       - Parses a JSON object containing an array of objects using
         VariableType.RecordType (no schema) and verifies that nested
         object properties (name, role) are preserved in each element.
       - This is the exact scenario from issue #4195 where objects in
         arrays were being returned as empty dictionaries.
    
    2. ParseList_ArrayOfObjects_NoSchema_PreservesProperties
       - Parses a JSON array of objects directly via ParseList with
         VariableType.ListType (no schema) and verifies all properties
         are preserved.
    
    Both tests follow the existing Arrange/Act/Assert pattern and would
    have failed before the DetermineElementType() fix (empty dictionaries
    instead of populated ones).
  • Python: Fixing issue #1366 - Thread corruption when max_iterations is reached. (#4234)
    * Fix thread corruption when max_iterations exhausted (#1366)
    
    When the function invocation loop exhausts max_iterations while the model
    keeps requesting tools, the failsafe code path (calling the model with
    tool_choice='none' and prepending fcc_messages) was unreachable because
    'if response is not None: return response' short-circuited before it.
    
    The fix removes the premature return so the failsafe always runs after
    loop exhaustion, making a final model call with tool_choice='none' to
    produce a clean text answer and prepending accumulated fcc_messages from
    prior iterations. This matches the existing pattern used by the error
    threshold and max_function_calls paths.
    
    Also unskips test_max_iterations_limit and test_streaming_max_iterations_limit
    which were previously skipped with 'needs investigation in unified API'.

  • Python: Fix doubled tool_call arguments in MESSAGES_SNAPSHOT when streaming (#4200)
    * fix: prevent doubled tool_call arguments in MESSAGES_SNAPSHOT
    
    When streaming with client-side tools, some providers send a full-
    arguments replay after the streaming deltas complete. The `_emit_tool_call`
    function unconditionally appends every arguments delta to the internal
    `flow.tool_calls_by_id` tracking dictionary via `+=`. When the replay
    contains the exact same complete arguments string that was already
    accumulated from prior deltas, the arguments get doubled (e.g.,
    `{"todoText":"buy groceries"}{"todoText":"buy groceries"}`).
    
    This causes `MESSAGES_SNAPSHOT` events to contain invalid doubled JSON in
    `tool_calls[].function.arguments`, breaking any client or middleware that
    relies on snapshots for state reconstruction.
    
    The fix adds a guard (mirroring the existing duplicate guard in
    `_emit_text`) that detects when the incoming delta exactly equals the
    already-accumulated arguments string, indicating a full-arguments replay
    rather than an incremental delta. In this case the append is skipped,
    preventing the doubling.
    
    The `ToolCallArgsEvent` deltas are still emitted correctly for real-time
    streaming — only the internal snapshot accumulator is guarded.
    
    Fixes #4194
    
    * fix: move duplicate check before event emission + add test
    
    Address Copilot review feedback:
    1. Move duplicate full-arguments replay detection BEFORE emitting
       ToolCallArgsEvent, for consistency with _emit_text() which returns
       early without emitting any events on replay detection.
    2. Add test_emit_tool_call_skips_duplicate_full_arguments_replay() to
       verify the duplicate detection behavior for tool call arguments,
       matching the existing test pattern for text content.

    * refactor: remove RUN_INTEGRATION_TESTS flag
    
    Integration test gating now uses two mechanisms:
    - `@pytest.mark.integration` for test selection via `-m` filtering
    - `skip_if_*_disabled` for credential/service availability checks
    
    The RUN_INTEGRATION_TESTS env var was redundant since the marker handles
    selection and the skip decorators already check for actual credentials.

  • Python: feat(python): Add embedding abstractions and OpenAI implementation (Phase 1) (#4153)
    * feat(python): Add embedding abstractions and OpenAI implementation (Phase 1)
    
    This PR contains two parts:
    
    1. **Overall migration plan** for porting vector stores and embeddings from
       Semantic Kernel to Agent Framework (docs/features/vector-stores-and-embeddings/README.md)
       covering all 10 phases from core abstractions through connectors and TextSearch.
    
    2. **Phase 1 implementation** — core embedding abstractions and OpenAI/Azure OpenAI
       embedding clients:
    
       Core types (_types.py):
       - EmbeddingGenerationOptions TypedDict (total=False)
       - Embedding[EmbeddingT] generic class with model_id, dimensions, created_at
       - GeneratedEmbeddings[EmbeddingT, EmbeddingOptionsT] list container with options, usage
       - EmbeddingInputT (default str) and EmbeddingT (default list[float]) TypeVars
    
       Protocol + base class (_clients.py):
       - SupportsGetEmbeddings protocol — Generic[EmbeddingInputT, EmbeddingT, OptionsContraT]
       - BaseEmbeddingClient ABC — Generic[EmbeddingInputT, EmbeddingT, OptionsCoT]
    
       Telemetry (observability.py):
       - EmbeddingTelemetryLayer with gen_ai.operation.name = "embeddings"
    
       OpenAI implementation (openai/_embedding_client.py):
       - RawOpenAIEmbeddingClient, OpenAIEmbeddingClient, OpenAIEmbeddingOptions
       - Uses _ensure_client() factory pattern
    
       Azure OpenAI implementation (azure/_embedding_client.py):
       - AzureOpenAIEmbeddingClient following AzureOpenAIChatClient pattern
       - Supports API key, Entra ID credentials, env var configuration
    
       Tests:
       - 47 unit tests for types, protocol, base class, OpenAI, and Azure clients
       - 6 integration tests (gated behind RUN_INTEGRATION_TESTS + credentials)
    
       Samples:
       - samples/02-agents/embeddings/openai_embeddings.py
       - samples/02-agents/embeddings/azure_openai_embeddings.py

    * fix: Handle base64 encoding_format in OpenAI embedding client
    
    When encoding_format='base64' is used, the OpenAI API returns base64-encoded
    floats instead of a JSON array. Decode these automatically to list[float]
    so the return type stays consistent regardless of encoding format.
    
    Also adds a unit test for base64 decoding and fixes minor docstring/import issues.

    * fix: Only record INPUT_TOKENS for embedding telemetry
    
    Embeddings have no output/completion tokens. Remove OUTPUT_TOKENS recording
    which was double-counting prompt_tokens via the total_tokens fallback.

    GeneratedEmbeddings is invariant in its type param, so the Protocol
    TypeVar cannot be covariant.

    * Python: Fix OpenAI chat client compatibility with third-party endpoints and OTel 0.4.14 (#4161)
    
    * Fix system message content sent as list instead of string
    
    Some OpenAI-compatible endpoints (e.g. NVIDIA NIM) reject system messages
    when content is a list of content parts. This change flattens system and
    developer message content to a plain string in the Chat Completions client.

    * Fix compatibility with opentelemetry-semantic-conventions-ai 0.4.14
    
    Version 0.4.14 removed several LLM_* attributes from SpanAttributes
    (LLM_SYSTEM, LLM_REQUEST_MODEL, LLM_RESPONSE_MODEL, LLM_REQUEST_MAX_TOKENS,
    LLM_REQUEST_TEMPERATURE, LLM_REQUEST_TOP_P, LLM_TOKEN_TYPE).
    
    Move these to the OtelAttr enum with their well-known gen_ai.* string values
    and update all references in observability.py and tests.

    * Flatten text-only message content to string for all roles
    
    Extend the system/developer fix to all message roles. Text-only content
    lists are now post-processed into plain strings, while multimodal content
    (text + images/audio) remains as a list. This fixes compatibility with
    OpenAI-like endpoints that cannot deserialize list content (e.g. Foundry
    Local's Neutron backend).

    * Fix streaming text lost when usage data in same chunk
    
    Some providers (e.g. Gemini) include both usage data and text content
    in the same streaming chunk. The early return on chunk.usage caused
    text and tool call parsing to be skipped entirely. Remove the early
    return and process usage alongside text/tool calls.

  • Python: Enhance Azure AI Search Citations with Document URLs in Foundry V2 (#4028)
    * Python: Enhance Azure AI Search citations with document URLs in Foundry V2 (Responses API)
    
    Override _parse_response_from_openai and _parse_chunk_from_openai in
    RawAzureAIClient to extract get_urls from azure_ai_search_call_output
    items and enrich url_citation annotations with document-specific URLs.
    
    - Non-streaming: first pass collects get_urls, post-processes annotations
    - Streaming: captures search output state, enriches url_citation events
      (also handles url_citation annotation type not handled by base class)
    - Updated V2 sample to demonstrate citation URL extraction
    - Added 14 unit tests covering extraction, enrichment, and edge cases
    
    Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
    
    * refactor: rework search citation enrichment to override _inner_get_response
    
    - Remove all direct openai/pydantic imports from _client.py
    - Override _inner_get_response instead of _parse_response_from_openai/_parse_chunk_from_openai
    - Use closure-local state for streaming instead of instance-level _streaming_search_get_urls
    - Add _build_url_citation_content helper for streaming url_citation handling
    - Fix mypy errors by using str(value or '') for Annotation TypedDict fields
    - Fix docstring to say 'citation' instead of 'url_citation'

    * fix: handle streaming search citations from output_item.done events
    
    The azure_ai_search_call_output item only has populated output data
    (including get_urls) in the response.output_item.done event, not in
    the response.output_item.added event. Also removed the search_get_urls
    guard on url_citation handling so annotations are always produced even
    if get_urls haven't been captured yet.

    Call super()._inner_get_response() independently in each branch instead

    two-arg super() in the closure; streaming uses cast() for type narrowing.

  • Python: Add max_function_calls to FunctionInvocationConfiguration (#2329) (#4175)
    * Add max_function_calls to FunctionInvocationConfiguration (#2329)
    
    Add a new per-request max_function_calls setting to FunctionInvocationConfiguration
    that limits the total number of individual function invocations across all iterations
    within a single get_response call. This complements max_iterations (which limits LLM
    roundtrips) by providing a hard cap on actual tool executions regardless of parallelism.
    
    - Add max_function_calls field to FunctionInvocationConfiguration (default: None/unlimited)
    - Track cumulative function call count in both streaming and non-streaming tool loops
    - Force tool_choice='none' when the limit is reached
    - Add validation in normalize_function_invocation_configuration
    - Improve docstrings for FunctionInvocationConfiguration, FunctionTool, and @tool
      to clarify semantics of max_iterations vs max_function_calls vs max_invocations
    - Add tests for parallel calls, single calls, unlimited mode, and config validation

    * Add sample for controlling total tool executions
    
    Showcases all three mechanisms for limiting tool executions:
    1. max_iterations — caps LLM roundtrips
    2. max_function_calls — caps total individual function invocations per request
    3. max_invocations — lifetime cap on a specific tool instance
    Plus a combined scenario demonstrating defense in depth.

    * Suppress ruff E305/fmt in hosting sample to preserve XML doc tags
    
    The XML snippet tags (# <create_agent> / # </create_agent>) are used for
    docs extraction and must stay adjacent to the code they wrap. Both ruff
    check (E305) and ruff format add blank lines after the function definition,
    pushing the closing tag away. Suppress with ruff: noqa: E305 and fmt: off.

    * Add per-agent tool wrapping scenario to control_total_tool_executions sample

    When converting base AgentRunOptions to ChatClientAgentRunOptions, the middleware
    now preserves AllowBackgroundResponses, ContinuationToken, and AdditionalProperties
    in addition to ResponseFormat.
    
    Added unit test verifying all properties are preserved during the conversion.

  • Python: Fix OpenAI chat client compatibility with third-party endpoints and OTel 0.4.14 (#4161)
    * Fix system message content sent as list instead of string
    
    Some OpenAI-compatible endpoints (e.g. NVIDIA NIM) reject system messages
    when content is a list of content parts. This change flattens system and
    developer message content to a plain string in the Chat Completions client.
    
    Fixes https://github.com/microsoft/agent-framework/issues/1407

    * Fix compatibility with opentelemetry-semantic-conventions-ai 0.4.14
    
    Version 0.4.14 removed several LLM_* attributes from SpanAttributes
    (LLM_SYSTEM, LLM_REQUEST_MODEL, LLM_RESPONSE_MODEL, LLM_REQUEST_MAX_TOKENS,
    LLM_REQUEST_TEMPERATURE, LLM_REQUEST_TOP_P, LLM_TOKEN_TYPE).
    
    Move these to the OtelAttr enum with their well-known gen_ai.* string values
    and update all references in observability.py and tests.
    
    Fixes https://github.com/microsoft/agent-framework/issues/4160

    * Flatten text-only message content to string for all roles
    
    Extend the system/developer fix to all message roles. Text-only content
    lists are now post-processed into plain strings, while multimodal content
    (text + images/audio) remains as a list. This fixes compatibility with
    OpenAI-like endpoints that cannot deserialize list content (e.g. Foundry
    Local's Neutron backend).
    
    Partially fixes https://github.com/microsoft/agent-framework/issues/4084

    * Fix streaming text lost when usage data in same chunk
    
    Some providers (e.g. Gemini) include both usage data and text content
    in the same streaming chunk. The early return on chunk.usage caused
    text and tool call parsing to be skipped entirely. Remove the early
    return and process usage alongside text/tool calls.
    
    Fixes https://github.com/microsoft/agent-framework/issues/3434

    * Fix mypy errors in _chat_client.py
    
    Rename shadowed variable 'args' in system/developer branch to 'sys_args'
    and rename loop variable 'content' to 'msg_content' to avoid type conflict.

  • Replace inline string literals with constants in ChatHistoryMemoryProvider (#4096)
    Extract 11 private const string fields for vector store property names
    (Key, Role, MessageId, AuthorName, ApplicationId, AgentId, UserId,
    SessionId, Content, CreatedAt, ContentEmbedding) and replace all inline
    usages across the collection definition, store dictionary, search result
    access, and filter expressions.

    - Use ProviderSessionState<State> for session-scoped state management (matching Mem0Provider pattern)
    - Replace constructor-based scope with stateInitializer delegate
    - Remove Serialize method (no longer on base class)
    - Add SearchInputMessageFilter, StorageInputMessageFilter, StateKey to options
    - Update sample to use AIContextProviders list instead of AIContextProviderFactory
    - Update unit and integration tests for new API
    - Add UTF-8 BOM encoding and --tl:off instructions to dotnet/AGENTS.md

  • .NET: [BREAKING] Workflows API Review Naming Changes (Part 1?) (#4090)
    * 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(...)
    
    * misc - part1: SwitchBuilder internal
