Before you get confused... its MVVM abbreviation for Model-View- View Model. It is very similar to MVC (In case you are not aware.. refer this .. http://en.wikipedia.org/wiki/Model%E2%80%93view%E2%80%93controller) . The View handles the UI part.. if you are using silverlight, the files with .xaml extension and the page design, they constitute the View. The Model consists of the containers (All the classes needed) and the VM i.e View Model contains all the business logic..
