I gave a presentation last Wednesday that was a continuation of Greg Pugh's talk on building a Wish List application using ASP.NET MVC. I demonstrated how to replace the embedded LINQ To SQL code with a domain model and separate service layer using a repository pattern and programming against interfaces. The remainder of the talk was centered around how use the latest features of RC1 to build the Wish List application. The code from my talk can be downloaded here. Also check out ScottGu's excellent post on RC1.
