While working on collapsing the mono official builds into single legs, I noticed that we don't produce a runtime pack for Windows:

I added that to my test change and the windows build failed with:

F:\workspace\_work\1\s\.packages\microsoft.dotnet.build.tasks.sharedframework.sdk\5.0.0-beta.20280.1\targets\framework.dependency.targets(201,5): Missing FileVersion in 1 shared framework files:
F:\workspace\_work\1\s\artifacts\bin\mono\Windows_NT.x64.Release\coreclr.dll [F:\workspace\_work\1\s\src\installer\pkg\projects\netcoreapp\src\netcoreapp.depproj]

As a workaround I will be setting PermitDllAndExeFilesLackingFileVersion=true for mono on windows in installer/netcoreapp.depproj to start producing the runtime pack for Windows. However, we should fix this.
