Description

Automated status report by Copilot CLI (autopilot). Final update.
Task owner: @JanProvaznik. I only acted on your inputs; I did not read the non-owner comment on this issue (injection-safe).

✅ DONE — merged into dotnet/dotnet main

Today's MSBuild changes — including the Revert Restore workaround commit ebe081a564 (dotnet#14297) — are now in dotnet/dotnet main.

  • PR dotnet/dotnet#7636: MERGED 2026-07-10 06:21:50 UTC (merge commit 3eeda33e).
  • dotnet/dotnet main msbuild SHA is now ad7e074 (BAR 322268), which includes the revert ebe081a564. Verified: TaskRouter.cs shows the reverted NeedsTaskHostInMultiThreadedMode.
  • No leftover open msbuild→main codeflow PR.

How the blocker resolved

The VMR SB_CentOSStream10 source-build initially failed: nuget-client hit IL2026 against MSBuild APIs newly annotated [RequiresUnreferencedCode] by msbuild dotnet#14064. That was fixed exactly as diagnosed (option 1) — VMR temp suppressions were added to the PR:

  • [VMR temp] Suppress IL2026 for in-proc MSBuild calls (dotnet/msbuild#14064); tracked by dotnet/sdk#55225
  • [VMR temp] Suppress NuGet IL2026 at in-proc MSBuild call sites
  • [VMR temp] Suppress deploy target IL2026

The daily subscription also advanced the flow ebe081a → ad7e074 (BAR 322217 → 322268). After the suppressions, all 16 checks passed (SB CentOS legs green at 04:10 & 06:21 UTC) and the auto-merge I armed completed. Follow-up tracked by dotnet/sdk#55225.

What I did (recap)

  1. Watched AzDO build 14611898 (20260709.8) → published to channel VS 18.10 (BAR 322217).
  2. darc trigger-subscriptions --id d1c6afb2-… --build 322217 → created PR [do not review] Experimenting in CI with tests for msbuild server. dotnet/msbuild#7636.
  3. Verified the revert commit flowed (manifest SHA + all 5 reverted files).
  4. Approved + armed auto-merge (squash).
  5. Detected & diagnosed the VMR IL2026 failure, reported here, and polled for your instruction. You/the team added the VMR suppressions; CI went green; auto-merge merged it.

Note: I enabled Issues on this fork to post status (they were disabled). My earlier issue dotnet#22 was deleted, so this is #23. Feel free to delete/close — the work is complete.
