These controls are collectively called the ASP.NET AJAX Control Toolkit. The reason you do not see a new section of AJAX server controls is that Microsoft has treated them as an open-source project instead of just blending them into Visual Studio 2008.ĭevelopers at Microsoft and in the community have been working on a series of AJAX-capable server controls that you can use in your ASP.NET applications. You might be wondering where the big new AJAX-enabled server controls are for this edition of Visual Studio 2008 if this is indeed a new world for building controls. Every AJAX enhancement added to your application will make your application seem more fluid and responsive to the end user. This is the framework to take your applications to the next level because there is so much that can be accomplished with it, including adding specific AJAX capabilities to your user and custom server controls.

While ASP.NET 3.5 comes with a built-in set of controls you can use to create AJAX-style web applications, one of the greatest benefits of AJAX is that its framework is extensible, which allows you and other developers to create your own AJAX controls by extending those that already exist.
