There was an article here: http://msdn.microsoft.com/en-us/library/Ee817667%28pandp.10%29.aspx
The first part of tut implemented this pattern with abstract classes. The second part shows an example with Interface class. But nothing in this article discusses why this pattern would rather use abstract or interface.
So what explanation (advantages of one over the other) would you give ? Not in general but for this precise pattern.
