C# here to stay?

Question

I've been working with C# for about six months. I'm considering investing a lot more time learning it. It's my first experience with an object oriented language. I'm thinking about studying for the MCAD and using C# to get through it. Will C# be a marketable language to know over the next five years? Does it have a real future? I searched for some articles on the Web but haven't found that much info. Thanks. C#novice
