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. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> 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. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * 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 --------- Co-authored-by: alliscode <bentho@microsoft.com> Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Python / .NET Samples - Restructure and Improve Samples (Feature Branc… (#4092) * Python: .NET Samples - Restructure and Improve Samples (Feature Branch) (#4091) * Moved by agent (#4094) * Fix readme links * .NET Samples - Create `04-hosting` learning path step (#4098) * Agent move * Agent reorderd * Remove A2A section from README Removed A2A section from the Getting Started README. * Agent fixed links * Fix broken sample links in durable-agents README (#4101) * Initial plan * Fix broken internal links in documentation Co-authored-by: crickman <66376200+crickman@users.noreply.github.com> * Revert template link changes;

 ### Multi-target framework tip
@@ -83,3 +86,45 @@ Just remember to run `dotnet restore` after pulling changes, making changes to p
 Unit tests target both .NET Framework as well as .NET Core. When running on Linux, only the .NET Core tests can be run, as .NET Framework is not supported on Linux.

 To run only the .NET Core tests, use the `-f net10.0` option with `dotnet test`.
+
+### Microsoft Testing Platform (MTP)
+
+Tests use the [Microsoft Testing Platform](https://learn.microsoft.com/dotnet/core/testing/unit-testing-platform-intro) via xUnit v3. Key differences from the legacy VSTest runner:
+
+- **`dotnet test` requires `--project`** to specify a test project directly (positional arguments are no longer supported).
+- **Test output** uses the MTP format (e.g., `[✓112/x0/↓0]` progress and `Test run summary: Passed!`).
+- **TRX reports** use `--report-xunit-trx` instead of `--logger trx`.
+- **Code coverage** uses `Microsoft.Testing.Extensions.CodeCoverage` with `--coverage --coverage-output-format cobertura`.
+- **Running a test project directly** is supported via `dotnet run --project <test-project>`. This bypasses the `dotnet test` infrastructure and runs the test executable directly with the MTP command line.
+
+- **Running tests across the solution** with a filter may cause some projects to match zero tests, which MTP treats as a failure (exit code 8). Use `--ignore-exit-code 8` to suppress this:
+
+```bash
+# Run all unit tests across the solution, ignoring projects with no matching tests
+dotnet test --solution ./agent-framework-dotnet.slnx --no-build -f net10.0 --ignore-exit-code 8
+```
+
+- **Running tests with `--solution` for a specific TFM** requires all projects in the solution to support that TFM. Not all projects target every framework (e.g., some are `net10.0`-only). Use `./dotnet/eng/scripts/New-FilteredSolution.ps1` to generate a filtered solution:
+
+```powershell
+# Generate a filtered solution for net472 and run tests
+$filtered = ./dotnet/eng/scripts/New-FilteredSolution.ps1 -Solution dotnet/agent-framework-dotnet.slnx -TargetFramework net472
+dotnet test --solution $filtered --no-build -f net472 --ignore-exit-code 8
+
+# Exclude samples and keep only unit test projects
+./dotnet/eng/scripts/New-FilteredSolution.ps1 -Solution dotnet/agent-framework-dotnet.slnx -TargetFramework net10.0 -ExcludeSamples -TestProjectNameFilter "*UnitTests*" -OutputPath dotnet/filtered-unit.slnx
+```
+
+```bash
+# Run tests via dotnet test (uses MTP under the hood)
+dotnet test --project ./tests/Microsoft.Agents.AI.UnitTests -f net10.0
+
+# Run tests with code coverage (Cobertura format)
+dotnet test --project ./tests/Microsoft.Agents.AI.UnitTests -f net10.0 --coverage --coverage-output-format cobertura --coverage-settings ./tests/coverage.runsettings
+
+# Run tests directly via dotnet run (MTP native command line)

+.SYNOPSIS
+    Generates a filtered .slnx solution file by removing projects that don't match the specified criteria.
+
+.DESCRIPTION
+    Parses a .slnx solution file and applies one or more filters:
+    - Removes projects that don't support the specified target framework (via MSBuild query).
+    - Optionally removes all sample projects (under samples/).
+    - Optionally filters test projects by name pattern (e.g., only *UnitTests*).
+    Writes the filtered solution to the specified output path and prints the path.
+
+.PARAMETER Solution
+    Path to the source .slnx solution file.
+
+.PARAMETER TargetFramework
+    The target framework to filter by (e.g., net10.0, net472).
+
+.PARAMETER Configuration
+    Optional MSBuild configuration used when querying TargetFrameworks. Defaults to Debug.
+
+.PARAMETER TestProjectNameFilter
+    Optional wildcard pattern to filter test project names (e.g., *UnitTests*, *IntegrationTests*).
+    When specified, only test projects whose filename matches this pattern are kept.
+
+.PARAMETER ExcludeSamples
+    When specified, removes all projects under the samples/ directory from the solution.
+
+.PARAMETER OutputPath
+    Optional output path for the filtered .slnx file. If not specified, a temp file is created.
+
+.EXAMPLE
+    # Generate a filtered solution and run tests
+    $filtered = ./dotnet/eng/scripts/New-FilteredSolution.ps1 -Solution dotnet/agent-framework-dotnet.slnx -TargetFramework net472
+    dotnet test --solution $filtered --no-build -f net472

+    # Generate a solution with only unit test projects
+    ./dotnet/eng/scripts/New-FilteredSolution.ps1 -Solution dotnet/agent-framework-dotnet.slnx -TargetFramework net10.0 -TestProjectNameFilter "*UnitTests*" -OutputPath filtered-unit.slnx
