13.3. Ajax.NET Professional

Ajax.NET Professional (available at www.ajaxpro.info) is an Ajax framework designed for use with the .NET framework, specifically ASP.NET. As with JPSpan and DWR, Ajax.NET allows developers to create classes on the server that can be accessed via the client. This is done by once again abstracting out the communication between client and server, providing cross-browser communication behind the scenes.

This framework uses the .NET version of reflection to inspect the classes and create a JavaScript interface. Ajax.NET Professional also takes advantage of a .NET feature called attributes, which are used to mark specific methods that should be available to the client. This allows developers to concentrate on the true object-oriented design without worrying about exposing sensitive methods to the client.

If you are using .NET 1.1, add a reference to AjaxPro.dll to your project; for .NET 2.0, add a reference to AjaxPro.2.dll. This should be done for every project/web site ...
