If your just getting started on a project or looking to revamp a esisting ASP Site to ASP.Net. Take a look at IBuySpy an Open Source Portal Available for Free Download at ASP.Net. There are two flavors to IBUYSPY E-Commerce and Portal I have no experience with the E-Commerce version however the Portal has proven to be a excellent time saver. The security system is a little hard to work with and an additional layer of abstraction would be helpful however over all it's a very good place to start if you want to develop a .Net Site. Various third parties have begun developing plug-ins for IBuySpy and selling them as addins with customizable code again saving a incredible amount of time when compared to developing from scratch. I am very impressed with IBuySpy and just thought I'd pass on the word.
