ASP.NET AJAX integrates client script libraries with the ASP.NET 2.0
server-based development framework. This new Web development technology from
Microsoft offers you the same type of development platform for client-based Web
pages that ASP.NET offers for server-based pages. And because ASP.NET AJAX is an
extension of ASP.NET, it is fully integrated with server-based services. ASP.NET
AJAX makes it possible to easily take advantage of AJAX techniques on the Web
and enables you to create ASP.NET pages with a rich, responsive UI, and server
communication. However, ASP.NET AJAX isn’t just for ASP.NET development. You can
take advantage of the rich client framework to easily build client-centric Web
applications that integrate with any backend data provider.
ASP.NET AJAX enables you to take full advantage of the capabilities of
the browser to deliver richer Web experiences that work on any modern
browser
ASP.NET AJAX enables ASP.NET developers to enrich their existing Web
applications with incredible ease
ASP.NET AJAX includes a rich client-side JavaScript framework that

behaviors.
ASP.NET AJAX makes it super easy to consume services from ASP.NET and to
build composite applications from services on the programmable Web.
The ASP.NET AJAX CTP provides additional features and functionality that work
alongside the ASP.NET AJAX core. Together, these releases enable development
scenarios supported in the earlier ASP.NET AJAX CTP releases in addition to
newly added functionality.
