Recommended architecture for a ASP.NET MVC 2/3 web application

I am looking for a ASP.NET MVC 2/3 project on Codeplex and alike with a good architecture for a mid-sized web appli开发者_运维百科cation. Does anyone knows of a good one?

Have a look at Sharp-Architecture and The Tekpub ASP.NET MVC 2.0 Starter Site. There is also MVC Turbine too

Get a copy of Pro ASP.NET MVC 2 by Steve Sanderson. He provides realistic guidance without over complicating the concept while addressing "the hard" questions.

There is a new edition of his book that targets MVC 3 that you might want to consider instead but I have not read that one yet so I cannot comment on it. I assume it is equally good, though.
