I'm looking for a good asp.net webforms reference application. 

We have some developers with VB6 experience, but no web application experience. I'd like to provide them with a couple of example apps that make use of a few simple forms, some user controls, db access, etc. An application that made use of a separate project for classes would be a nice bonus.

There seem to be a lot of very simple examples/tutorials for given features, but I can't find a good reference app that covers all of the above-mentioned topics.

Any suggestions?
