Hour 5. Data Communication with the Server

What You’ll Learn in This Hour:

Different data interchange formats between client and server An introduction to JSON Working with JSON

In Hour 2, “Understanding the ASP.NET Ajax Architecture,” we looked at the architecture of ASP.NET Ajax, which gave us a glimpse of the components in the Microsoft Ajax Client Library and the ASP.NET server extensions. One of the layers in the Client Library included the Component Layer, which comprises a set of nonvisual components providing support for asynchronous communication, XML, and JSON serialization. The ASP.NET server framework communicates with the Client Library with the help of the Component Layer in the Client Library. This hour throws light on JSON—JavaScript Object Notation, pronounced “Jason”—apart from covering XML and string formats.
