Seriously? I mean, I'm doing my job using the, let's call them, open-source languages: javascript, php, bit of python, java and perl, but, still, I would say that C# is better than most of them, both in terms of the lanuage syntax, features and such, as well as in terms of the quality of libraries. That it's sort of Microsoft-platforms-only keeps me away, but I have to give a credit where it's due: C# is a great piece of technology.
