Need to add "Compile Include ..." to use files generated during the build but this causes more errors

Steps to reproduce

The attached project uses <Compile Include="$(IntermediateOutputPath)\*.cs" /> so GrammarParser is recognized. But usage of Compile causes others problems in Problems view and with dotnet cli.

If I remove Compile the project builds correctly with dotnet cli, but then OmniSharp does not recognize GrammarParser.

Correct. It will only regenerate the files when MSBuild runs. That happens on initial project loading and during build.

It won’t generate the files simply by passing that variable, but it will with my full OmniSharp change. The project needs to be restored first though. There is an issue in OmniSharp where it won’t reload a project after a restore in some cases (and this is one of them). However, if the project is already restored, the files will be generated when OmniSharp loads the project. I just tried this to verify.
