Double write during publish

See original GitHub issue

Publishing a self-contained WPF template app writes some files twice because ResolvedFileToPublish has the same dll from different runtime packs (for example, Microsoft.Win32.Registry.dll comes from both netcoreapp and the windowsdesktop pack). This causes crossgen failures when used together with PublishReadyToRun=true.

Looks very similar to which was addressed in, but I’m still seeing this with version 3.0.100-preview6-012031.

/cc @fadimounir @nguerrera @peterhuene

edit: it fails during PublishReadyToRun=true only when used together with the linker. Without linking, the duplicates are already crossgen’d, and so they don’t hit the failure. In any case, ResolvedFileToPublish has duplicates that shouldn’t be there, and we end up with DoubleWrites of some files.

I have a fix locally for the satellite duplicates. It comes down to an msbuild batching behavior that I don’t actually understand yet. 😊 I will add some test coverage and also file a discussion issue on the msbuild repo so I can solidify my understanding and help future me and others with similar issues.

It makes me nervous to have this excluded from ref for NETCore.App and excluded for runtime in Window.Desktop, but I guess that’s not much different than having an assembly in WindowsDesktop use all the API exposed… I guess we could do that @dagood what do you think?

I probably don’t know the full range of things to be nervous about with this–the concrete thing I can think of is the files disappearing from NETCoreApp’s runtime, breaking WindowsDesktop runtime. I’m pretty sure VerifyClosure wouldn’t catch that since it only looks at NETCoreApp’s References, but maybe it could be enhanced? Then we could make some change (not necessarily in VerifyClosure) to catch duplicate assemblies with the same versions to change to ref-only. Filed

But that just solves duplicates between NETCoreApp and WindowsDesktop, not sibling frameworks like WindowsDesktop and AspNetCore, so making publish nicely handle duplicates still seems necessary. Removing duplicates would just be to reduce FDD and dev-time disk usage.
