what's the general way of separating classes?

Well yes, but really that's very different. 'Using' statements are 
solely for the purpose of convenience so you don't have to qualify 
classes with namespaces. They aren't necessary to actually *use* those 
classes.

(The true 'include' functionality comes in the References, which are 
shared across all files on account of them being compiled together.)

Yes, true. I was just thinking of a program all contained in one namespace.
