.NET: Bump Microsoft.Extensions.AI packages to 10.6.0, align transitive dependency floor, and update Merge Gatekeeper ignores

[Copilot]

Motivation and Context

This updates the .NET dependency graph to the latest Microsoft.Extensions.AI.* 10.6.0 line and aligns related package floors so restore succeeds without downgrades. It also updates remaining explicit references so the repo consistently resolves to the same AI package generation.

Additionally, this adjusts Merge Gatekeeper behavior to ignore an external review check that is failing outside this repository’s boundaries and should not block merges.

Description

• Dependency version uplift

  • Central package versions in dotnet/Directory.Packages.props were moved to 10.6.0 for:
    • Microsoft.Extensions.AI
    • Microsoft.Extensions.AI.Abstractions
    • Microsoft.Extensions.AI.Evaluation
    • Microsoft.Extensions.AI.Evaluation.Quality
    • Microsoft.Extensions.AI.Evaluation.Safety
    • Microsoft.Extensions.AI.OpenAI

• Transitive floor alignment (NU1109 resolution)

  • Raised centrally managed transitive dependencies required by Microsoft.Extensions.AI 10.6.0:
    • Microsoft.Extensions.DependencyInjection.Abstractions → 10.0.8
    • Microsoft.Extensions.Logging.Abstractions → 10.0.8
    • Microsoft.Bcl.AsyncInterfaces → 10.0.8
    • System.Diagnostics.DiagnosticSource → 10.0.8
    • System.Text.Json → 10.0.8
    • System.Threading.Channels → 10.0.8

• Explicit reference consistency

  • Updated the pinned sample reference in
    dotnet/samples/02-agents/AgentWithRAG/AgentWithRAG_Step05_Neo4jGraphRAG/AgentWithRAG_Step05_Neo4jGraphRAG.csproj:
    • Microsoft.Extensions.AI.OpenAI 10.4.0 → 10.6.0

• Merge Gatekeeper ignore list update

  • Updated .github/workflows/merge-gatekeeper.yml to add review to IGNORED_NAMES.
  • This prevents external/non-repo review check failures (Failing checks: review) from blocking merges.

@copilot Please consider bumping the OpenAI package also to 2.10.0 as part of this change.

@copilot Please consider bumping the OpenAI package also to 2.10.0 as part of this change.

OpenAI is already set to 2.10.0 in /tmp/workspace/microsoft/agent-framework/dotnet/Directory.Packages.props (<PackageVersion Include="OpenAI" Version="2.10.0" />). No additional package bump was needed.

Pull request overview

Updates the repo’s .NET package graph to consistently resolve Microsoft.Extensions.AI.* at 10.6.0 and raises a handful of centrally-managed transitive “floor” packages to prevent restore downgrade/conflict errors.

Changes:

• Bumped centrally-managed Microsoft.Extensions.AI* packages to 10.6.0 in dotnet/Directory.Packages.props.
• Raised centrally-managed transitive dependency floors (e.g., System.Text.Json, DiagnosticSource, *.Abstractions) to 10.0.8 to align with the new AI package line.
• Updated the one sample project that opts out of central package management to explicitly reference Microsoft.Extensions.AI.OpenAI 10.6.0.

@copilot Please create another PR skipping the TestServerWithDevUI_ResolvesWorkflows_WithKeyedAndDefaultRegistrationAsync flacky test and also create a reference issue to track this to bring it back with consistent behavior.

[Copilot]

@rogerbarreto I've opened a new pull request, #6159, to work on those changes. Once the pull request is ready, I'll request review from you.

@copilot Ok and what is the quarantine issue number?

@copilot Please update the Merge GateKeeper to also ignore the REVIEW check Failing checks: review this is happening outside of the boundaries of this repository.

@copilot Please update the Merge GateKeeper to also ignore the REVIEW check Failing checks: review this is happening outside of the boundaries of this repository.

Implemented in 724060c. Merge Gatekeeper now ignores the external review check by adding it to IGNORED_NAMES, so Failing checks: review won’t block merges.
