This broke the runtime repo:

D:\a\1\s\.packages\microsoft.dotnet.arcade.sdk\5.0.0-beta.19568.10\tools\SymStore.targets(22,41): error MSB4057: The target "CoreCompile" does not exist in the project. [D:\a\1\s\src\libraries\build.proj]
##[error].packages\microsoft.dotnet.arcade.sdk\5.0.0-beta.19568.10\tools\SymStore.targets(22,41): error MSB4057: (NETCORE_ENGINEERING_TELEMETRY=Build) The target "CoreCompile" does not exist in the project.

We could work around this and add the CoreCompile target of course but I would like to understand/discuss the break first.

I'll take a look.

I think we can fix it by replacing CoreCompile, which is only available in managed projects, with Build.
