Unlike the other helpers, this one uses static class helpers to serialize and deserialize, hence it is a little bit easier than the others to use.

using Newtonsoft.Json;

var rawJSON      = "{\\"Name\\":\\"Fibonacci Sequence\\",\\"Numbers\\":[0, 1, 1, 2, 3, 5, 8, 13]}";
var fibo         = JsonConvert.DeserializeObject<Dictionary<string, object>>(rawJSON);
var rawJSON2     = JsonConvert.SerializeObject(fibo);
