It seems that others have tried to do this, and failed. For now, I think the only solution is to use Mono.
Mono is not a good solution, because it is no longer being maintained (as far as I can tell) and is already
6 versions of C# behind. However, until somebody fixes CodeRunner to work with dotnet, it is probably
the best I can do.
