I am new here and managed to create a Monogame solution/project in Visual Studio for Mac by following the instructions above, but I'm basically on the same page as @Fletch.
According to a tutorial on this site, it should have quite a few other files and should be able to run. That is not the case, unfortunately.
So what are my options? Should I wait for some kind member of this community (like @dellis1972) to provide a solution?
