build this using a recent preview8 SDK like this: dotnet publish -r win-x64 -c release , then run the exe produced under bin\x64\release\netcoreapp3.0\win-x64\publish\

global.json

{
  "sdk": {
    "version": "3.0.100-preview8-013417"
  }
}

Observed: Crash - FileNotFoundException for System.Diagnostics.Debug.dll

When producing ReadyToRun images, the ILLinker is configured to skip C++/CLI images. See dotnet/linker#651 and dotnet/linker#658.

In turn, this results in a failure of dependencies of such assemblies (like System.Diagnostics.Debug.dll, which is required by DirectWriteForwarder.dll) from being identified and included in the ReadyToRun images.

[vatsan-madhavan]

This depends on dotnet/linker#675

Closing - this seems to be working in preview 8 3.0.100-preview8-013656
