Anthem.NET provides AJAX support to ASP.NET 1.1 and 2.0. Like most .NET libraries, it provides indirect AJAX, where portions of your templates are rewritten by the library to make AJAX calls. It works by mapping the standard ASP.NET control model into an AJAX environment. This includes full support for view state and server-side events.

Atlas is Microsoft's AJAX toolkit that provides tight integration with ASP.NET 2.0 and Visual Studio. The toolkit is designed so that .NET developers can add AJAX to their applications by using widgets and indirect AJAX and without editing code. In indirect AJAX, the Atlas code takes current ASP.NET templates and rewrites their links and form actions, making them post to the server using AJAX calls. The toolkit also includes visual effects, drag-and-drop support, automatic user profiles, data-binding widgets, and support for Windows Live widgets.

MagicAJAX.NET focuses on providing AJAX support without your needing to write JavaScript code. You can do this by adding an AJAX control to your pages and then rewriting current controls. MagicAJAX.NET also has some support for writing JavaScript from .NET (including helper methods). Communication with the server is done with URL-encoded POSTs to the server. In such situations, the server returns JavaScript code.
