Alternate Solution for JSON Serialization
You can find source code from : http://json.codeplex.com/
using (FrameworkContainer fc = new FrameworkContainer())
var realObject = fc.GetAccountInformation("AmitGajjar");
using (MemoryStream ms = new MemoryStream())
var result = from account in realObject
Name = account.Account_Name,
City = account.Address1_City,
Phone = account.Address1_Telephone
var serializedObject = JsonConvert.SerializeObject(result);
Hope this will help you to implement serialization very quickly.
