[WPF] Article about the Model-View-ViewModel design pattern, by Josh Smith

Soon after the release of WPF, people have been talking more and more about “Model-View-ViewModel” (MVVM). This expression refers to a design pattern, drawing its inspiration from the Model-View-Controller (MVC) and Presentation Model (PM) patterns, and created specifically to take advantage of WPF features. This patterns enables an excellent decoupling between data, behavior and presentation, which makes the code easier to understand and maintain, and improves the collaboration between developers and designers.
