I just saw this post in the ASP.NET forums. It says that if you were to re-build the IBuySpy Portal application in ASP.NET 2.0 that there would be 70% less code!! I can't imagine what has been done to allow this, but I am excited!
Update: Hmmm... now that I think about it. Generics alone would probably save quite a bit of code, but you could do that now by using my free CodeSmith application to simulate generics.
