We're working with IEnumerable<T> and things like that. So the basics behind generics, if you're not familiar with them, is that the person that creates the type, they create the generic item, they create the generic class with the generic interface with the generic method. And then the developer that's using that type, they decide when they're writing the code what the real type will be for that generic method or that generic class at runtime.
