Before this question WPF interviewer can ask you to explain WPF command and bindings. You can read about WPF command and bindings from this link http://dotnetinter.livejournal.com/87390.html.


MVVM in the most used architecture because of command and bindings facility provided by WPF. WPF MVVM is incomplete without command and bindings.



Command and bindings helps you to connect view (WPF UI) with view model class without writing lot of behind code. Binding connects the UI input elements (textbox, combo box etc.)with the view model class properties and the UI actions like button click, right click are connected to the methods of the class by commands.
