Dave has a fantastic and very detailed post about our implementation of the Observer pattern in ASP.NET Ajax 4.0 . This feature is what enables the live bindings to work.

Well, bindings are really implemented by a component, Sys.Binding, and a markup extension, which...

You may have read that from John Resig or Scott Guthrie . I’m very excited to announce that Microsoft has decided to ship, adopt and support using jQuery on top of ASP.NET. This may come as a surprise to some of you but I hope you’ll agree with me that it makes total sense. jQuery is a fantastic JavaScript...

I'm sharing a spot with Scott Cate (of CloudDB fame, and by the way CloudDB is a fantastic product built entirely using ASP.NET AJAX) this week on Hanselminutes.
