The dotnet/sdk team is migrating core MSBuild tasks to support multithreaded execution, unblocking the entire test suite from xUnit to MSTest.

Two critical build tasks shipped migrations to `IMultiThreadableTask` [1][2], fixing long-standing MSBuild compatibility issues that prevented parallel builds. This is foundational work for a larger push: the SDK is building MSTest infrastructure to onboard ~53 test projects off xUnit [3], a move that requires first decoupling the shared test framework from xUnit's shallow but pervasive coupling [4]. Separately, SignalR's Swift client bumped MessagePack to 8.0.28 [5] and replaced stored secrets with GitHub OIDC for e2e authentication [6], eliminating long-lived connection strings from CI. WinForms pulled routine codeflow updates from the VMR [8], and the SDK fixed misspellings in error messages across multiple files [7].

Action items

→ Review multithreaded task migrations in your builds - test for race conditions if you use ComputeStaticWebAssetsTargetPaths or DiscoverPrecompressedAssets dotnet/sdk [plan]
→ Track the MSTest framework migration PR - this unblocks 53 test projects moving off xUnit dotnet/sdk [monitor]
→ Rotate any stored SignalR connection strings - OIDC auth is now the pattern dotnet/signalr-client-swift [plan]
