Regenerate XLF with UpdateXlf to remove the repeated package source mapping resource key that fails CI localization validation. Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com>

@dotnet/source-build It looks like this needs a re-bootstrap to bring in an MSBuild fix that should fix a packaging failure.

Can we re-bootstrap as needed or is there anything we need to wait for?

AI Analysis

Windows x86 packaging is failing due to a mismatch between the package cache used during restore and the one used during the subsequent build. In [build 1661044](https://dev.azure.com/dnceng-public/public/_build/results?buildId=1661044), Roslyn’s PackageReleasePackages target fails at BuildReleasePackages.targets(17,5):

error MSB4036: The "Microsoft.DotNet.Tools.UpdatePackageVersionTask" task was not found.

The binlog shows that restore generated package imports pointing to src\runtime\artifacts\.packages, while the build evaluates NuGetPackageRoot as src\roslyn\artifacts\.packages. The import that registers the packaging task is guarded by Exists, so it is silently skipped when the package is absent from the Roslyn cache.

I reproduced this failure pattern with CI’s exact bootstrap SDK, 12.0.100-alpha.1.26480.102. Multithreaded MSBuild’s TaskHost environment handling can replace the build’s virtual NUGET_PACKAGES value with its process-startup value. This matches dotnet/msbuild#15032, whose fix is present in the VMR sources but absent from the older bootstrap SDK.

The preferred resolution is to re-bootstrap onto an SDK containing that fix. Explicitly passing the intended cache as global RestorePackagesPath also avoids the failure in the reproducer, as does /mt:false; disabling node reuse alone does not. The full Windows x86 packaging leg still needs confirmation.

Looks like we have one pending: #10625

Yes, @akoeplinger is driving that. I'm just a reviewer :)

akoeplinger · 2026-11-03T17:09:40Z

lol and I just noticed the rebootstrap is broken in part because it's missing some sdk change :) I think I can workaround that though.

ProjectData's publish output ships NuGet.Versioning in the SDK layout. Keep transitive pinning disabled for regular builds, but enable it in source-only builds so the dependency resolves to the source-built version and has a matching symbol file.

The previous commit hit a test failure:

Output:

Did not find PDBs for the following SDK files:
/__w/1/s/artifacts/obj/extracted-dotnet-sdk/sdk/12.0.100-ci/ProjectData/NuGet.Versioning.dll

The missing symbol failure comes from tool_projectdata.csproj publishing an older NuGet.Versioning.dll whose matching PDB isn’t in the current source-build symbols. Despite being a layout helper, its PackageReference publishes runtime dependencies too; CopyBuildOutputToPublishDirectory=false only excludes the helper’s own assembly.

Transitive pinning was disabled in dotnet/sdk#56753 to avoid NU1109 errors caused by NuGet’s build-number wraparound, described in #9985. Main’s package versions no longer require that workaround, but the standalone SDK’s release/11.0.2xx branch still has the stale central pin.

I cherry-picked b1872a2 from #10468 to keep main and 11.0.2xx aligned: re-enable transitive pinning in source-only builds so ProjectData ships the current source-built dependency, while preserving regular-build behavior.

@dsplaisted @nagilson @ViktorHofer @mthalman I wonder if we need the NuGet.Versionining.dll in the ProjectData folder. I assume it could just use the one in the SDK root folder instead? looks like this is what e.g. Microsoft.NET.Build.Tasks already does:

dotnet/src/sdk/src/Tasks/Microsoft.NET.Build.Tasks/Microsoft.NET.Build.Tasks.csproj
