The latest and greatest CTP of Atlas is available now. You can check it out here and download it. This CTP also includes the “Go Live” license so you can use this version in your applications and produce production code.
I have been using Atlas in some test projects and it appears Microsoft is producing some nice AJAX features we can use without having to be a JavaScript expert.
This announcement came from MIX’06 and you can find more information here as well.
