Ajax Client Framework in ASP.NET

The ASP.NET Ajax client framework is essentially comprised of a set of JavaScript files that form part of a library commonly called the Microsoft Ajax Library.

The major components that are included in this library are the following:

• Component Layer
• Core Services Layer
• Browser Compatibility Layer

Core Component Layer

The Component Layer is comprised of a set of nonvisual components that provide support for asynchronous communication, networking, localization, XML and JSON serialization, ASP.NET application services, and so on.

Core Services Layer

The Core Services Layer contains the ASP.NET Ajax Base Class Library and its extensions, which facilitate object-oriented programming and an extension to the existing JavaScript types.

Browser Compatibility Layer

The Browser Compatibility Layer is responsible for providing cross-browser support for Ajax-enabled web pages—that is, support for browsers such as IE, Mozilla, Firefox, and so on.
