Does .NET 4 have a built-in JSON serializer/deserializer?

Does .NET 4 come with any class that serializes/deserializes JSON data?

Use this generic class in order to serialize / deserialize JSON. You can easy serialize complex data structure like this:

Dictionary<string, Tuple<int, int[], bool, string>>

to JSON string and then to save it in application setting or else

public class JsonSerializer
{
    public string Serialize<T>(T Obj)
    {
        using (var ms = new MemoryStream())
        {
            DataContractJsonSerializer serialiser = new DataContractJsonSerializer(typeof(T));
            serialiser.WriteObject(ms, Obj);
            byte[] json = ms.ToArray();
            return Encoding.UTF8.GetString(json, 0, json.Length);
        }
    }

    public T Deserialize<T>(string Json)
    {
        using (var ms = new MemoryStream(Encoding.UTF8.GetBytes(Json)))
        {
            DataContractJsonSerializer serialiser = new DataContractJsonSerializer(typeof(T));
            var deserializedObj = (T)serialiser.ReadObject(ms);
            return deserializedObj;
        }
    }
}

.NET4 has a built-in JSON Class,such as DataContractJsonSerializer ,but it is very weak,it doesn't support multidimentional array. I suggest you use JSON.Net

You can use the DataContractJsonSerializer class anywhere you want, it is just a .net class and is not limited to WCF. More info on how to use it here and here.

There's the JavaScriptSerializer class (although you will need to reference the System.Web.Extensions assembly the class works perfectly fine in WinForms/WPF applications). Also even if the DataContractJsonSerializer class was designed for WCF it works fine in client applications.
