When the community stops worrying about how to do basic things in a particular technology and starts working out how to do complex things well, you know the technology has reached a point of maturity. The emergence of architectural patterns and testing capabilities for a platform are a good indicator that the technology is ready for real-world use in nontrivial applications.

One of the main patterns to be applied to Silverlight is the Model-View-ViewModel (MVVM) pattern, also known as the ViewModel pattern.

Note

MVVM or ViewModel Pattern? Different groups like to call it different things. I’ll use both interchangeably until the community settles on one over the other. There are some influential folks on both sides of this debate.
