Summary

In this chapter, we got our feet wet with MVVM. We started things off with a quick review of the history of the pattern and its basic structure. We then covered the technologies in WPF and Silverlight that enable MVVM. Next, we built a version of the Project Billing sample application using MVVM and followed this by looking at the benefits of the pattern. We talked briefly about some of the issues and pain points with implementing MVVM and then finished off the chapter by looking at the MVVM Light toolkit that we will use later in this book.
