Yes the additions that were added to support Linq makes c# (imho) the most advanced production language today. By advanced I mean it's fully supported, everything works as intended. It's not academic. I can use advanced features today for real work and get full IDE support and good documentation.

I just built a search engine. I was able to make it massively parallel with some trivial parallel linq code. The power of Linq and the parallel extensions is just amazing.
