Motivation & Context

SteerableLongRunningIntegrationTests.ActiveMafTurn_QueuesSteeringThenRunsItOnTheSameSessionAsync fails intermittently in .NET CI (net10.0, ubuntu-latest): the assertion right after submitting the steering request expects agent.RunCount == 1 but observes 2. Root cause is unknown — it may be test synchronization or a runtime behavior regression — so this PR is an interim mitigation to unblock CI while investigation continues under issue #8376.

Description & Review Guide

  • What are the major changes?

    • Single test-only change in dotnet/tests/Microsoft.Agents.AI.Foundry.Hosting.UnitTests/SteerableLongRunningIntegrationTests.cs, using the repository's existing xUnit skip convention:

      [Fact(Skip = "Temporarily skipped: flaky in CI (observed RunCount 2 instead of 1); see https://github.com/microsoft/agent-framework/issues/8376")]
      public async Task ActiveMafTurn_QueuesSteeringThenRunsItOnTheSameSessionAsync()
    • Test body and every assertion are preserved verbatim, so the sequential-execution and session-continuity guarantees remain encoded for when the test is re-enabled.

  • What is the impact of these changes?

    • Exactly one test is newly skipped; the Microsoft.Agents.AI.Foundry.Hosting.UnitTests project reports 464 total / 463 passed / 1 skipped. No production code, other tests, project files, or CI workflows are touched.
    • Coverage for the steering queue/session-reuse path is temporarily lost. Issue .NET: Stabilize steering harness session reuse test #8376 stays open for root-cause analysis and removal of the skip.
  • What do you want reviewers to focus on?

    • Whether the skip reason and issue link are sufficient to prevent this from silently becoming permanent.
