A few days after I've pointed my RSS reader to the Rhino.Mocks Google Group There is an announcement form the author of RhinoMocks that a brand new version 3.0 is released yesterday.
On top of this he has been making a screen cast that explains how to use RhinoMocks. The video is almost one hour long but I think is definitely worth watching as it shows you how it all works very well. In order to see the video you must install the Camtasia TSCC codec wich you can download here (it's the first link on the page)
One tip for the author, Ayende: could you please turn off Resharper next time you do a screen cast. Seeing you edit code with that tool is a little hard to follow if you don't use it yourself.
Happy mocking indeed
