From the "What's new" page for R#:
"Source Generators are almost certainly the most talked about feature in the C# compiler. It’s understandable: the ability to create new code right in the compilation process and use it immediately is exciting and could be useful in lots of different situations."
Are you completely f#&king mad? They are an insanely dangerous idea. Have you ever seen people do that sort of thing? It's even worse than the sh!t they normally write!!!
The only acceptable thing R# can do is delete such crap immediately!!!!!!
