deps.json for ProjectReferences is not emitted correctly

[vatsan-madhavan]

When I create a project with a project reference like this...

<ProjectReference Include="..\WindowsBase.csproj" />

... the deps.json file that's generated has an entry like this:

      "WindowsBase/1.0.0": {
        "runtime": {
          "WindowsBase.dll": {}
        }
      }

The application loads WindowsBase from Microsoft.NetCore.App instead of loading the one supplied by the referenced project.

Repro: XUnitTestProject1.zip

You can contrast this to a raw file reference which includes fileversion / assemblyversion. For some reason fileversion and assemblyversion are missing from projectreferences. This breaks the scenario where folks submodule a library to replace it (or in this case WPF just tries to test their own libs which in the case of WindowsBase overlap libs in the base shared framework). /cc @dsplaisted

Also happening in WinForms, deps files contain no version for facades referenced by test projects via ProjectReference and for System.Drawing that means it'll take the one supplied by Microsoft.NetCore.App instead of the one built in the WinForms repo. (Other facades for the various *.Design assemblies don't have a counterpart in Microsoft.NetCore.App as far as I can see.)

I bet you can workaround by using both a project reference and a raw file reference.

yeah having both kinds of references seems to be a useable workaround, loads the right System.Drawing now
