ASP.NET Ajax框架

Is there an ASP.NET AJAX framework other than just using UpdatePanel & Friends or the ASP.NET AjaxControlToolkit?

Any suggestions?

Telerik has a nice library of AJAX controls.

The new ASP.NET MVC Framework (beta)?

Infragistics is popular, but gets wonky when you actually have to debug a problems.

There are tons of Ajax Frameworks for ASP.NET. Some of them are; Anthem.NET, Ra-Ajax (my project), Gaia Ajax, AjaxPro.NET and probably hundreds of others. My personal favorite (shameless plug) is obvously Ra-Ajax since that's what I am working with. (founder of)

Have a look at Ajax Calendar Starter-Kit to see its capabilities...
