?Technical Evangelist Matt Winkler meets up with Eugene Osovetsky and Ghenadie Plingau, a PM and developer, from the WCF team to talk about returning JSON from a WCF service. JSON (JavaScript Object Notation) is s text based serialization of a JavaScript object, allowing one to new up a variable right from the string of JSON. Eugene hows how a developer can use the WCF programming model to serve JSON to AJAX clients. We also talk about how this is implemented in WCF as well as cool applications of this, namely to call WCF services from AJAX. He then shows off a cool tank game sample that allows two individuals to compete via a JavaScript game that is communicating with WCF.
