VsCodium is the FOSS version of Visual Studio Code, i.e. it is the same code without the private/proprietary addition added when Microsoft packages it. Making it possible to package and publish VSCodium is great, but, without getting in the discussion of how lame this is, the dotnet debugger published by Micro$oft can only be used by Micro$oft published software, meaning not VSCodium. (Did you know the same restriction applies to usage of the VSCode Marketplace?
