why no c# native compilor project on sf.net?
Nowadays open source projects are almost everywhere, especially for compilers, c++ compilers, pascal compilers, even for d language, go language, but why there is not a c# compiler, which works on native windows/linux? Is there any legal restrictions, or any technical barrier? or no market requirement?

I was wondering on this question for quite a long time.
