You should also try my ServiceStack JsonSerializer - it s the fastest  NET JSON serializer at the moment based on the benchmarks of the leading JSON serializers and supports serializing any POCO Type  DataContracts  Lists Dictionaries  Interfaces  Inheritance  Late-bound objects including anonymous types  etc   Basic Example  var customer   new Customer   Name  Joe Bloggs   Age 31    var json   customer ToJson    var fromJson   json FromJson lt Customer gt        Note  Only use Microsofts JavaScriptSerializer if performance is not important to you as I ve had to leave it out of my benchmarks since its up to 40x-100x slower than the other JSON serializers
