When you need to create CRUD screens in WPF how can you create them in such a way as to be testable and maintainable? Using control aggregation and class inheritance is a great way to build each piece of the CRUD screen.

In this seminar you build a user maintenance screen to present a list of users and a place to edit users. You are going to use several different controls and classes to build this complete screen.
