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.

$ nix build -L .#default.passthru.fetch-deps -o fetch-deps
$ ./fetch-deps deps.json

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
      '';
