I'm well aware :) just wanted to clarify since this comes up a lot.
I spent most of last year maintaining a Web Forms app. It's no fun. Ironically, there used to be many more CLR languages, because Microsoft paid for their development. IronPython and IronRuby stand out. I wish ClojureCLR weren't dead too.
As I wrote below, I misjudged the project because of the low activity in its issues. Clearly the projects are not managed through GitHub, which is what I am used to. I made a mistake.
Plus on UNIX, Java has 25 years of history, not 4 (not counting WIP mono here).
