Using JSON with ASP.NET 3.5

Using JSON with ASP.NET 3.5: "Using JSON with ASP.NET 3.5"

Almost any application that you write will involve exchanging data from a client application to the server. This process involves selecting a data format and exchange protocol that will be required to enable this communication. When it comes to selecting these data formats, you have a variety of open standards that you can consider and the ideal choice depends on the requirements of the application.
For example, if you use SOAP based Web services, you format the data in an XML payload that is wrapped within a SOAP envelope. Although XML works well for many application scenarios, its inherent chatty nature makes it less than ideal for certain scenarios. For example, in an AJAX style Web application, you make asynchronous lightweight out-of-band calls to the server side to get the required data without even refreshing the browser. In this scenario, you need a lightweight, open, text-based platform independent data exchange format for transferring data back and forth between the client and server. That’s exactly what the JSON (Java Script Object Notation) standard provides.
This article will discuss the use of JSON in ASP.NET Web applications. In addition, you will also see how to use JSON as a data format for exchanging data from a WCF service to an AJAX based ASP.NET Web application.
