How to serialize an object in windows phone 7 - json

Question

How to convert an object to JSON data in windows phone. In web application I have used following code
JavaScriptSerializer serializer = new JavaScriptSerializer();
string stringData = serializer.Serialize(object);
I want to get the same output as that of the above code in windows phone 7.

Answer 1

JavaScriptSerializer is not supported on Windows Phone. An alternative is to use JSON.NET (you can add it via NuGet).
The code will then look like this:
string stringData = JsonConvert.SerializeObject(object);
