Introduction
If you work with Silverlight or WPF, you have probably met the phrase “MVVM”. Almost everyone who is anyone in the WPF / Silverlight scene has their own MVVM framework, and their own way of explaining and teaching MVVM. Scary terms like IoC, Dependency Injection, Commanding Frameworks, Event Aggregators, Unit Testing, etc just roll off the tongue of the MVVM experts. This is one of the reasons why MVVM is intimidating for a lot of people. Still, you can create perfectly valid MVVM applications without even knowing what those terms mean.
