This PR fixes a critical deadlock issue in Visual Studio when building React Native Windows C++ projects. The problem occurred when MSBuild targets called the
Restoretarget during theBeforeResolveReferencesphase of Visual Studio builds.Problem
The
BeforeResolveReferencestarget in bothMicrosoft.ReactNative.Common.targetsandvnext/Directory.Build.targetswas calling the NuGetRestoretarget whenBuildingInsideVisualStudiowas true. This caused several issues:Solution
Removed the problematic
BeforeResolveReferencestargets that were callingMSBuildtasks withTargets="Restore". Visual Studio has its own built-in NuGet package restoration mechanisms that handle this properly without the deadlock risk.The fix includes:
BeforeResolveReferencestargets from both affected filesFiles Changed
vnext/PropertySheets/External/Microsoft.ReactNative.Common.targetsvnext/Directory.Build.targetsBoth files had identical problematic patterns that have been resolved.
Fixes #15108.
