That's funny to me because my experience was the exact opposite. After an undergrad experience of Java, C, C++, Python (at least from the OO/C-likes) on *nix systems, trying C# 5 w/ VS2010 + ReSharper was some kind of transcendent experience.

I LOVE the language and I've found the entire ecosystem fine. There are some corner cases for some more advanced systems level stuff, but I've yet to be unable to do something I needed to.

Java feels like a clunky dinosaur to me now. But hey, different strokes for different folks.
