  • .NET: Add hosted agent observability sample (#5660)
    * .Net: Add hosted agent observability sample
    
    Mirrors the Python sample added in #5608 for Foundry hosted agents. The
    .NET hosting library already wires OpenTelemetry automatically via
    Microsoft.Agents.AI.Foundry.Hosting (ApplyOpenTelemetry) plus
    Azure.AI.AgentServer.Core's AddAgentHostTelemetry, so no framework
    changes are needed. The sample is documentation plus a runnable artifact
    that produces an interesting span tree (invoke_agent / agent_invoke /
    chat / execute_tool).
    
    Adds Hosted-Observability under FoundryHostedAgents/responses with two
    small tools (GetCurrentLocation, GetWeather), agent.yaml /
    agent.manifest.yaml declaring OTEL_INSTRUMENTATION_GENAI_CAPTURE_MESSAGE_CONTENT
    (the .NET equivalent of Python's ENABLE_SENSITIVE_DATA), Dockerfile +
    Dockerfile.contributor, .env.example and README explaining the .NET vs
    Python defaults. Project added to agent-framework-dotnet.slnx.
    
    * Address PR feedback: use Random.Shared and add .dockerignore
  • .NET: Support returning durable workflow results from HTTP trigger endpoint (#5321)
    * Adding support for "wait for response" when invoking workflow http endpoint.
    
    * update changelog.
    
    * PR comment fixes.
    
    * Address PR review feedback.
    
    - Return 404 Not Found when no orchestration with the given ID exists
    - Return 200 OK for failed workflows (the HTTP operation succeeded;
      the workflow outcome is conveyed via the response body)
    - Rename 'status' to 'workflowStatus' in WorkflowRunResponse to avoid
      inconsistency with AgentRunSuccessResponse which uses integer status
    - Add optional 'error' field (omitted from JSON when null) to
      WorkflowRunResponse for failed workflow details
  • .NET: Bump OpenTelemetry packages to 1.15.3 (#5478)
    * Bump OpenTelemetry packages to 1.15.3 to fix known vulnerabilities
    
    Update OpenTelemetry packages from 1.15.0 to 1.15.3 in Directory.Packages.props
    to resolve NU1902 warnings-as-errors for CVEs GHSA-g94r-2vxg-569j,
    GHSA-mr8r-92fq-pj8p, and GHSA-q834-8qmm-v933.
    
    Add explicit PackageReference for OpenTelemetry.Exporter.OpenTelemetryProtocol
    in Foundry.Hosting and OpenTelemetry.Api + OpenTelemetry.Exporter.OpenTelemetryProtocol
    in Hosted-Invocations-EchoAgent to override transitive 1.15.0 resolution in
    projects with CentralPackageTransitivePinningEnabled=false.

    * update a2a agent to the latest a2a sdk (#5257)
    
    * Move A2A samples from 04-hosting to 02-agents (#5267)
    
    Move the A2A sample projects (A2AAgent_AsFunctionTools and
    A2AAgent_PollingForTaskCompletion) from samples/04-hosting/A2A/ to
    samples/02-agents/A2A/ to better align with the sample directory
    structure. Update solution file and samples README accordingly.

    * .NET: Fix stream reconnection for A2AAgent (#5275)
    
    * Add SSE stream reconnection support to A2AAgent
    
    Implement automatic reconnection for SSE streams that disconnect mid-task,
    using the Last-Event-ID header to resume from where the stream left off.
    
    Changes:
    - Add InvokeStreamingWithReconnectAsync method to A2AAgent with configurable
      max retries and delay between attempts
    - Add new log messages for reconnection events
    - Add A2AAgent_StreamReconnection sample demonstrating the feature
    - Update existing polling sample to use simplified SendMessageAsync API
    - Add unit tests for stream reconnection logic

    * Add DI wiring verification tests for AddA2AServer
    
    Add three tests to A2AServerServiceCollectionExtensionsTests that verify
    custom keyed services are actually wired through to the A2AServer, not
    just that the server resolves non-null:
    
    - Custom IAgentHandler: verifies the keyed handler is invoked when
      processing a SendMessageRequest instead of the default A2AAgentHandler.
    - Custom AgentSessionStore (no handler): verifies the keyed session
      store's GetSessionAsync is called during request processing when no
      custom handler is registered.
    - Default stores end-to-end: verifies the InMemoryAgentSessionStore and
      InMemoryTaskStore defaults successfully process a request. Uses a new
      CreateAgentMockForRequests helper that includes SerializeSessionCoreAsync
      setup needed by InMemoryAgentSessionStore.
    
    All tests call A2AServer.SendMessageAsync directly (no HTTP layer needed)
    and use CancellationToken timeouts to guard against hangs.

    * Catch agent errors and emit response.failed with real error message
    
    Previously, unhandled exceptions from agent execution would bubble up
    to the SDK orchestrator, which emits a generic 'An internal server
    error occurred.' message — hiding the actual cause (e.g., 401 auth
    failures, model not found, etc.).
    
    Now AgentFrameworkResponseHandler catches non-cancellation exceptions
    and emits a proper response.failed event containing the real error
    message, making it visible to clients and in logs.
    
    OperationCanceledException still propagates for proper cancellation
    handling by the SDK.
    
    Also bumps package version to 0.9.0-hosted.260403.2.

    * Add Invocations protocol samples (hosted echo agent + client) (#5278)
    
    Add Hosted-Invocations-EchoAgent: a minimal echo agent hosted via the
    Invocations protocol (POST /invocations) using AddInvocationsServer and
    MapInvocationsServer, bridged to an Agent Framework AIAgent through a
    custom InvocationHandler.
    
    Add SimpleInvocationsAgent: a console REPL client that wraps HttpClient
    calls to the /invocations endpoint in a custom InvocationsAIAgent,
    demonstrating programmatic consumption of the Invocations protocol.
    
    Both samples default to port 8088 for consistency with other hosted
    agent samples.
    
    * Restructure FoundryHostedAgents samples into invocations/ and responses/
    
    Align dotnet hosted agent samples with the Python side (PR #5281) by
    reorganizing the directory structure:
    
    - Remove HostedAgentsV1 entirely (old API pattern)
    - Split HostedAgentsV2 into invocations/ and responses/ based on protocol
    - Move Using-Samples accordingly (SimpleAgent to responses, SimpleInvocationsAgent to invocations)
    - Update slnx with new project paths and add previously missing invocations projects
    - Update README cd paths from HostedAgentsV2 to invocations or responses
    - Rename .env.local to .env.example to match Python naming convention
    - Fix format violations in newly included invocations projects
    
    * Remove launchSettings, use .env for port configuration
    
    - Delete all launchSettings.json files (port 8088 now comes from ASPNETCORE_URLS in .env)
    - Add DotNetEnv to Hosted-Invocations-EchoAgent so it loads .env like the responses samples
    - Create .env.example for EchoAgent with ASPNETCORE_URLS and ASPNETCORE_ENVIRONMENT
    - Add AGENT_NAME to ChatClientAgent and FoundryAgent .env.example (required by those samples)
    - Add AZURE_BEARER_TOKEN=DefaultAzureCredential to all .env.example files
    - Update DevTemporaryTokenCredential in all 6 samples to treat the sentinel value
      as unavailable, allowing ChainedTokenCredential to fall through to DefaultAzureCredential
    - Update EchoAgent README with Configuration section
    
    * Use placeholder for AGENT_NAME in Hosted-FoundryAgent .env.example
    
    * Move FoundryResponsesHosting to responses/Hosted-WorkflowHandoff, use GetResponsesClient
    
    * Rename Hosted-Workflows to Hosted-Workflow-Simple, Hosted-WorkflowHandoff to Hosted-Workflow-Handoff
    
    * Remove FoundryResponsesRepl and empty FoundryResponsesHosting directory
    
    * Add Dockerfiles, README, agent yamls and bearer token support to Hosted-Workflow-Handoff
    
    - Add Dockerfile and Dockerfile.contributor for Docker-based testing
    - Add agent.yaml and agent.manifest.yaml with triage-workflow as primary agent
    - Add README.md following sibling pattern, noting Azure OpenAI vs Foundry endpoint
    - Add DevTemporaryTokenCredential and ChainedTokenCredential for Docker auth
    - Register triage-workflow as non-keyed default so azd invoke works without model
    - Update .env.example with AZURE_BEARER_TOKEN sentinel
    - Add .gitignore to 04-hosting to suppress VS-generated launchSettings.json
    - Fix docker run image name in Hosted-Workflow-Simple README

    * Net: Prepare Foundry Preview Release (#5336)
    
    * Prepare Foundry preview release 1.2.0-preview.*
    
    Bump VersionPrefix to 1.2.0 and update the preview stamp date. Invert packaging opt-in so only the Foundry preview set produces NuGet packages:
    
    - Microsoft.Agents.AI.Abstractions
    
    - Microsoft.Agents.AI
    
    - Microsoft.Agents.AI.Workflows
    
    - Microsoft.Agents.AI.Workflows.Generators
    
    - Microsoft.Agents.AI.Foundry
    
    Flip IsReleased=false on the preview set so they pick up the -preview.YYMMDD.N suffix. Gate GeneratePackageOnBuild on IsPackable=true. Remove the global IsPackable=true from nuget-package.props so the repo-level default (false) applies to everything else.
    
    * Lower preview VersionPrefix to 0.0.1
    
    Retroactive preview publish: bump VersionPrefix and GitTag from 1.2.0 to 0.0.1 so the 5 Foundry preview packages emit as 0.0.1-preview.260417.1.
    
    * Net: Publish all packages as 0.0.1-preview.260417.2 (#5341)
    
    Revises the Foundry pre-release approach to publish ALL normally packable src projects as preview packages stamped 0.0.1-preview.260417.2, including projects previously flagged IsReleased=true or with a non-default VersionSuffix (rc/alpha).
    
    nuget-package.props:
    
    - Collapse the four conditional PackageVersion expressions (IsReleaseCandidate, VersionSuffix, default preview, IsReleased stable) into a single unconditional 0.0.1-preview.260417.2. On this preview-only branch every package ships with the same pre-release stamp regardless of per-project flags.
    
    - Restore the global IsPackable=true default (offsetting the repo-wide IsPackable=false in Directory.Build.props). Projects that opt out (Mem0, Declarative) already set IsPackable=false AFTER importing this file so they remain non-packable.
    
    - Remove the IsReleased-gated EnablePackageValidation line. Package validation does not apply to a 0.0.1 preview.
    
    csproj reverts (Abstractions, Agents.AI, Workflows, Workflows.Generators, Foundry):
    
    - Revert the IsPackable=true opt-in block introduced in #5336 (now redundant since the props default is true again).
    
    - Restore IsReleased=true to its pre-PR value. The setting is now a no-op because the props no longer branches on it.
    
    * Bump preview version to 260420.1 and fix AgentServer package deps (#5367)
    
    - Bump PackageVersion to 0.0.1-preview.260420.1
    - Bump Azure.AI.AgentServer.Core beta.21 -> beta.22 (required by
      Azure.AI.AgentServer.Responses beta.3)
    - Replace AgentHostTelemetry.ResponsesSourceName with local constant
      (type made internal in AgentServer.Core beta.22)

    * .NET: Hosted agents toolbox support (#5368)
    
    * feat: Add Foundry Toolbox (MCP) support to AgentFrameworkResponseHandler
    
    Adds support for Foundry Toolsets MCP proxy integration in the hosted agent
    response handler. Toolsets connect at startup via IHostedService, gating the
    readiness probe per spec §3.1. MCP tools are injected into every request's
    ChatOptions and OAuth consent errors (-32006) are intercepted and surfaced as
    mcp_approval_request + incomplete SSE events.
    
    New files:
    - FoundryToolboxOptions.cs: configuration POCO for toolset names and API version
    - FoundryToolboxBearerTokenHandler.cs: DelegatingHandler with Azure Bearer token
      auth, Foundry-Features header injection, and 3x exponential backoff on 429/5xx
    - McpConsentContext.cs: AsyncLocal-based per-request consent state shared between
      the tool wrapper and the response handler
    - ConsentAwareMcpClientTool.cs: AIFunction wrapper that catches -32006 errors and
      signals consent via shared state and linked CancellationTokenSource
    - FoundryToolboxService.cs: IHostedService that creates McpClient per toolset at
      startup and exposes cached tools
    
    Modified files:
    - AgentFrameworkResponseHandler.cs: injects toolbox tools into ChatOptions, sets
      up linked CTS consent interception, emits mcp_approval_request on -32006
    - ServiceCollectionExtensions.cs: adds AddFoundryToolboxes(params string[]) extension
    - Microsoft.Agents.AI.Foundry.csproj: adds ModelContextProtocol and Azure.Identity
      dependencies under NETCoreApp condition
    
    Sample:
    - Hosted-Toolbox: minimal hosted agent sample using AddFoundryToolboxes
    
    * Rename toolset to toolbox in user-facing API; rename ConsentAwareMcpClientTool to ConsentAwareMcpClientAIFunction
    
    * Add HostedMcpToolboxAITool for client-selectable Foundry toolboxes
    
    Introduces HostedMcpToolboxAITool, a marker tool subclassing HostedMcpServerTool that rides the OpenAI Responses 'mcp' wire format to let clients request a specific Foundry toolbox per request.
    
    - New FoundryAITool.CreateHostedMcpToolbox(name, version?) factory.
    
    - FoundryToolboxOptions.StrictMode (default true) rejects unregistered toolboxes; set to false to allow lazy-open on first use.
    
    - FoundryToolboxService.GetToolboxToolsAsync(name, version?) resolves cached or lazy-opened MCP tools.
    
    - AgentFrameworkResponseHandler parses request.Tools for foundry-toolbox://name[?version=v] markers and injects resolved tools per request, merging with pre-registered ones.
    
    - Unit tests for marker parsing and strict-mode resolution.
    
    * Bump Azure.AI.Projects to 2.1.0-alpha; add ToolboxRecord/ToolboxVersion factory overloads + tests
    
    * Fix PR review issues: retry off-by-one, URI encoding, docs, tests, build
    
    - Fix off-by-one in FoundryToolboxBearerTokenHandler retry loop (4 attempts → 3)
    - URI-encode version parameter in HostedMcpToolboxAITool.BuildAddress
    - Add XML doc clarifying version pinning is reserved for future use
    - Add comment clarifying AddHostedService deduplication safety
    - Fix DevTemporaryTokenCredential expiry to use DateTimeOffset.MaxValue
    - Fix AgentCard ambiguity in A2AServer sample with using alias
    - Add 18 new unit tests for retry handler and ReadMcpToolboxMarkers

    * Split Foundry into stable V1 and preview Hosting package
    
    Extract hosted agent functionality from Microsoft.Agents.AI.Foundry into a
    new Microsoft.Agents.AI.Foundry.Hosting preview package. This resolves NU5104
    build errors caused by the stable Foundry package depending on prerelease
    Azure SDK packages (Azure.AI.AgentServer.Responses, Azure.AI.Projects beta).
    
    Changes:
    - Create Microsoft.Agents.AI.Foundry.Hosting with VersionSuffix=preview,
      targeting .NET Core only (net8.0/9.0/10.0)
    - Move all Hosting/ source files to the new project
    - Move ToolboxRecord/ToolboxVersion overloads to FoundryAIToolExtensions
    - Revert Azure.AI.Projects to 2.0.0 in Directory.Packages.props;
      Hosting uses VersionOverride for 2.1.0-beta.1
    - Clean V1 Foundry csproj: remove beta deps, ASP.NET Core ref, hosting conditionals
    - Update 8 hosted agent sample projects to reference Foundry.Hosting
    - Split unit tests: ToolboxRecord/ToolboxVersion tests moved to Hosting/
    - Add Foundry.Hosting to solution file
    
    Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
    
    * Address PR review comments: experimental attrs, doc fixes, token propagation
    
    - Add [Experimental(OPENAI001)] to all 7 public Hosting types per reviewer request
    - Fix McpConsentContext XML doc: 'Thread-static' -> 'Async-local' (AsyncLocal
      flows with ExecutionContext, not thread-static)
    - Expand UserAgentMiddleware test regex to match prerelease versions (e.g. 1.0.0-rc.4)
    - Propagate CancellationToken in AgentFrameworkResponseHandler session save
    
    Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
    
    * Remove unnecessary MEAI001 suppression from stable Foundry package
    
    MEAI001 was a leftover from when Hosting code lived in the same project.
    The stable V1 Foundry package builds clean without it, and suppressing
    experimental diagnostics in a released package can hide unintentional
    exposure of experimental APIs to consumers.

    The integration test asserts that WorkflowOutputEvent is found in the

    only emitted via explicit YieldOutputAsync calls, the assertion would
    fail. Added YieldOutputAsync to each executor to match the test
    expectation and demonstrate the API in the sample.

    * .NET: [Feature Branch] Add Human In the Loop support for durable workflows (#4358)
    
    * Add Azure Functions HITL workflow sample
    
    Add 06_WorkflowHITL Azure Functions sample demonstrating Human-in-the-Loop
    workflow support with HTTP endpoints for status checking and approval responses.
    
    The sample includes:
    - ExpenseReimbursement workflow with RequestPort for manager approval
    - Custom HTTP endpoint to check workflow status and pending approvals
    - Custom HTTP endpoint to send approval responses via RaiseEventAsync
    - demo.http file with step-by-step interaction examples
    
    * PR feedback fixes
    
    * Minor comment cleanup
    
    * Minor comment clReverted the `!context.IsReplaying` guards on `PendingEvents.Add`/`RemoveAll` and `SetCustomStatus` in `ExecuteRequestPortAsync`. The guards broke fan-out scenarios where parallel RequestPorts      need to be discoverable after replay. `SetCustomStatus` is idempotent metadata that doesn't affect replay determinism.eanup

    * Bump Microsoft.DurableTask.Worker to 1.19.1 to fix version downgrade
    
    Microsoft.Azure.Functions.Worker.Extensions.DurableTask 1.13.1 requires
    Microsoft.DurableTask.Worker >= 1.19.1 via its transitive dependency on
    Microsoft.DurableTask.Worker.Grpc 1.19.1.

    * Fix build errors from main merge: Throw conflict, ExecuteAsync rename, GetNewSessionAsync rename
    
    - Remove InjectSharedThrow from DurableTask csproj (uses Workflows' internal Throw via InternalsVisibleTo)
    - Update ExecuteAsync -> ExecuteCoreAsync with WorkflowTelemetryContext.Disabled
    - Update GetNewSessionAsync -> CreateSessionAsync

    * Move durable workflow samples to 04-hosting/DurableWorkflows
    
    Aligns with main branch sample reorganization where durable samples
    live under 04-hosting/ (alongside DurableAgents/).
    
    - Move samples/Durable/Workflow/ -> samples/04-hosting/DurableWorkflows/
    - Add Directory.Build.props matching DurableAgents pattern
    - Update slnx project paths
    - Update integration test sample paths
    - Update README cd paths and cross-references

    * Fix build errors: remove duplicate base class members, update renamed APIs
    
    - Remove duplicate OutputLog, WriteInputAsync, CreateTestTimeoutCts, etc. from
      ConsoleAppSamplesValidation (already in SamplesValidationBase)
    - Update AddFanInEdge -> AddFanInBarrierEdge in workflow samples
    - Update GetNewSessionAsync -> CreateSessionAsync in workflow samples
    - Update SourceId -> ExecutorId (obsolete) in workflow samples

    * Fix dotnet format issues: add UTF-8 BOM and remove unused using
    
    - Add UTF-8 BOM to 20 .cs files across DurableTask, AzureFunctions,
      unit tests, and workflow samples
    - Remove unnecessary using directive in 07_SubWorkflows/Executors.cs

    * Fix GetExecutorName to handle agent names with underscores
    
    Split on last underscore instead of first, and validate that the
    suffix is a 32-char hex string (sanitized GUID) before stripping it.
    This prevents truncation of agent names like 'my_agent' when the
    executor ID is 'my_agent_<guid>'.

    * Align DurableTask.Client.AzureManaged to 1.19.1
    
    Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
    
    * Bump DurableTask and Azure Functions extension package versions
    
    - DurableTask.* packages: 1.19.1 -> 1.22.0
    - Functions.Worker.Extensions.DurableTask: 1.13.1 -> 1.16.0
    - Functions.Worker.Extensions.DurableTask.AzureManaged: 1.0.1 -> 1.5.0 (telemetry bug fix)

    * Bump DurableTask SDK packages to 1.22.0
    
    - DurableTask.Client: 1.19.1 -> 1.22.0
    - DurableTask.Client.AzureManaged: 1.19.1 -> 1.22.0
    - DurableTask.Worker: 1.19.1 -> 1.22.0
    - DurableTask.Worker.AzureManaged: 1.19.1 -> 1.22.0
    - Azure Functions extensions kept at original versions (1.13.1/1.0.1) due to
      host-side DurableTask.Core 3.7.0 incompatibility with newer extensions

    * Update Microsoft.Azure.Functions.Worker.Extensions.DurableTask to "1.16.0"
    
    * Add the local.settings.json files to the sample which were previously ignored. This aligns with our other samples.
    
    * Increase timeout for tests as CI has them failing transiently.
    
    * increaset timeout value for azure functions integration tests.
    
    * Add YieldsOutput(string) to workflow shared state sample executors
    
    ValidateOrder and EnrichOrder call YieldOutputAsync with string messages,
    but only their TOutput (OrderDetails) was in the allowed yield types.
    This caused TargetInvocationException in the WorkflowSharedState sample
    validation integration test.
    
    * Downgrade the durable packages to 1.18.0
    
    * Downgrading Worker.Extensions.DurableTask to 1.12.1
