MSDN has an article about some of the new features in C#/Whidbey. It's a pretty neat article that talks about the language enchancements and new features in Visual Studio. I'm most interested in Generics and Partial Types at this point. Generics will give me an easy way to create custom collections of business objects. I'll be able to define one “generic” collection that all my business objects can use. Right now I'm creating type specific collections.
