MSDN has published a good article on the new services, controls, and features in ASP.NET 2.0. I remember attending an internal Microsoft conference about a year ago, deciding to sit in on Scott Guthrie’s talk on the upcoming version of ASP.NET, and being wowed at the features that his team is building. Not only can you expect a healthy increase in development productivity, but you can also enable scenarios that have traditionally been very difficult to implement.
