Scott blogs about three new features in C# 3.5 (and two of them also apply to VB). All three of them are simple, but still very useful since they all let you do less typing and therefor become more productive. The three are Automatic Properties, Object Initializers and Collection Initializers. A while ago he also blogged about som of the new ASP.NET features for the Orcas timeframe. If you haven't been reading Scotts blog before and are interested of Orcas, now might be a good time to start subscribing. I find his blog one of the better in my blogroll, with most of the post containing really useful tips and information.
