I am not sure if it fixes the debug web project issue where it insists on validating everything when you just want to debug the application. You can get it at the link below.

If you are interested in WCF (Indigo), then this site is a good place to start. It has articles, faqs, videos, samples, and all sorts of useful stuff.
The January CTP of Atlas came out today. It has a number of improvements in the UpdatePanel which are pretty cool. Once I feel better, I'll actually post some working demos here and how everything works. For the mean time, if you are feeling adventurous you can download the latest Atlas at the link below.
