ASP.NET AJAX is an ASP.NET framework from Microsoft for quickly creating interactive and highly-personalized Web experiences that work across all the most popular browsers.

With ASP.NET AJAX, you can:

  • Create next-generation interfaces with reusable AJAX Hosting components.
  • Enhance existing Web pages using powerful AJAX controls with support for all modern browsers.
  • Continue using Visual Studio 2005.
  • Access remote hosting services and data directly from the browser without writing a lot of complicated script.
  • For more information, see the Official Microsoft ASP.NET AJAX site.

NOTE: ASP.NET AJAX is only available on Windows accounts with ASP.NET 2.0 enabled.
ASP.NET AJAX assembly (System.Web.Extensions.dll) is installed in the global assembly cache (GAC). Do not include the assembly in the Bin folder of your AJAX-enabled Web site.
