ASP.NET AJAX / Microsoft AJAX is dead?

While reading the book “Programming Microsoft ASP.NET MVC by Dino Esposito (May 14, 2010)”, I learned client side data binding.

The technology mentioned in the book is Microsoft Ajax / ASP.NET Ajax and the Sys.UI.DataView component. I want to try it out myself, but i can barely find any documentation online, not to mention any official.

After google for “Is ajax dead?”, I find lots of blog posts to indicate that Jquery is the first choice right now.

If anyone is interested in the original posts, below is the link.
