I am trying to create a site using the ASP MVC Framework. Some of the documentation use the IRepository pattern to abstract the information being sent to the view for rendering, while others recommend using a ViewModel (as in MVVC).

What is the difference?

Aren't these the same concept?

Thanks in advance
