Trimmed publish tests fail on IL3050 AOT analyzer warnings

[Widthdom]

Summary

On current origin/main, full dotnet test tests/CodeIndex.Tests/CodeIndex.Tests.csproj reaches the trimmed publish tests and fails because the test-internal dotnet publish treats IL3050 AOT analyzer diagnostics as errors.

Observed failing test:

• CodeIndex.Tests.QueryCommandRunnerTests.RunPublishedTrimmedCli_SerializesQueryJsonAndErrorJson

Representative diagnostics include ActiveWorkspace.cs, WorkspaceCommandRunner.cs, CdidxConfigFile.cs, SuggestionStore.cs, McpServer.cs, and other JSON serialization call sites using APIs annotated with RequiresDynamicCodeAttribute.

Repro

dotnet test tests/CodeIndex.Tests/CodeIndex.Tests.csproj /p:WarningsNotAsErrors=IL2026%3BIL2067%3BIL2072%3BIL2075%3BIL3050

The outer test build can be made to continue by demoting IL3050, but the test-internal trimmed dotnet publish still fails on IL3050.

Notes

This was found while validating unrelated issue fixes and is not part of that implementation scope.

Work started on branch codex/fix-issue2801.

I could not reproduce this on the latest origin/main (8245d3b) from branch codex/fix-issue2801.

Validation performed:

• dotnet test tests/CodeIndex.Tests/CodeIndex.Tests.csproj --filter "FullyQualifiedName~QueryCommandRunnerTests.RunPublishedTrimmedCli_SerializesQueryJsonAndErrorJson" /p:WarningsNotAsErrors=IL2026%3BIL2067%3BIL2072%3BIL2075%3BIL3050
  • Passed for net8.0 and net9.0.
• dotnet test tests/CodeIndex.Tests/CodeIndex.Tests.csproj --filter "FullyQualifiedName~QueryCommandRunnerTests.RunPublishedTrimmedCli_SerializesQueryJsonAndErrorJson"
  • Passed for net8.0 and net9.0.
• dotnet test tests/CodeIndex.Tests/CodeIndex.Tests.csproj --filter "FullyQualifiedName~RunPublishedTrimmedCli"
  • Passed; macOS arm64 skipped the known alias publish test as expected.
• dotnet test tests/CodeIndex.Tests/CodeIndex.Tests.csproj
  • Passed for net8.0 and net9.0 on the pre-fast-forward checkout; after fast-forward, the only upstream change was a changelog fragment, and the target test was rerun successfully.

No code change or changelog fragment is needed for this branch because the reported IL3050 trimmed publish failure is already fixed on current main.

Closing as already fixed on current origin/main based on the validation above.
