I agree with your last statement naithemilkman. Learning your first programming language will be the hardest part much like learning your first primary language. You will pickup all the basics and rules while learning how to think through a program. If you have a support group the knows and understands C# then that seems like a good choice for you. I've really enjoyed learning and using C# myself and I try to keep out of the politics of one language or company versus another when it comes to the languages. It's helped me that I work in a C# web development company so I have a large support group as well. You've already got the right idea, pickup one language and stick with it and you're on your way to developing those prototypes.
