    # We're pinning to an SDK version by using Nix anyway, so it's not super

So this seems to have worked fine. Thank you again for the thoughts!

Hey, I'm here again to cause issues. :P
I'm trying to work with Nuke.Common to properly do part of a build, and fetch-deps is throwing MSBUILD : error MSB1009: Project file does not exist.

You might want to look at avalonia in nixpkgs. It's the only package using nuke that comes to mind. One of the things it does is:

      configurePhase = ''
        runHook preConfigure
        for project in nukebuild/_build.csproj dirs.proj; do
          for rid in $runtimeIds; do
            dotnet restore --runtime "$rid" "$project"
          done
        done
        runHook postConfigure
      '';
