JSON serialization and de-serialization in WCF DataContracts

With XML becoming a thing of past for inter process communication and data exchange on the Internet infrastructures, JSON is more increasingly getting popular for providing quicker and better packaging of data across the wires. To be specific, as the need for partial rendering of web pages increases with the dynamic exchange of data using AJAX-enabled Web services, JSON has become more compact and simpler means to communicate between client calls and server processes thus providing a rich user experience. Moreover, Windows Communication Foundation (WCF) processes JSON messages using an internal, hidden mapping between JSON data and the XML infoset for data exchange.
