I'll merge this once we got the all-clear for 3.1-preview3

F:\workspace_work\1\s.dotnet\sdk\3.1.100-preview1-014400\Sdks\NuGet.Build.Tasks.Pack\build\NuGet.Build.Tasks.Pack.targets(198,5): error NU5104: A stable release of a package should not have a prerelease dependency. Either modify the version spec of dependency "Microsoft.AspNetCore.Mvc.Razor.Extensions.Version1_X [3.1.0-ci, )" or update the version field in the nuspec. [F:\workspace_work\1\s\src\Razor\src\Microsoft.AspNetCore.Razor.LanguageServer.Common\Microsoft.AspNetCore.Razor.LanguageServer.Common.csproj]

@dougbu @aspnet/build any ideas on the above error? The same thing is happening in every build, but is only treated as an error on Windows Debug. Also seeing it in dotnet/efcore#18804

Not sure why there are differences in error behavior, but you'll find that you can't stabilize in some cases until all the inputs are stabilized.
