Yes, it's called the namespace. The book fumbled on this (and many other things). You'll see namespaces used everywhere classes are defined. Often you can have more than one class with the same name. They can coexist because each can be in their own namespace. Namespaces help distinguish one class from another. Just like you can have two peopled named Kimo. One that lives on Maui and the other on Oahu. I'm monitoring all the threads. So, I'll see whatever is posted in the forum for ASP.net MVC.
