Monotouch с Newtonsoft не работает

Question

Я очень новичок в разработке Monotouch/iOS. Я использую

========== 
MonoDevelop 2.8.8.4 
Installation UUID: 0d3db625-7df9-4282-9aa6-177c25a46d07 
Runtime: 
     Mono 2.10.9 (tarball Tue Mar 20 15:31:37 EDT 2012) 
     GTK 2.24.10 
     GTK# (2.12.0.0) 
Mono for Android not installed 
Apple Developer Tools: 
     Xcode 4.2.1 (834) 
     Build 4D502 
Monotouch: 5.2.10 (Evaluation) 
========== 

Я пытаюсь сериализовать объект в строку json, используя Newtonsoft 3.5 all.

Очень простой код, но не работает .. Может кто-нибудь может помочь мне ...

partial void Action_Clicked (MonoTouch.Foundation.NSObject sender) 
{ 
    myDTO test = new myDTO(); 
    string teststring = ObjToJSON(test); 
} 

public string ObjToJSON(myDTO oObject) //Old function name is ObjToJSON_WithWrapper 
{ 
    string sJSON = ""; 
    sJSON = Newtonsoft.Json.JsonConvert.SerializeObject(oObject); 
    return sJSON; 
} 

public myDTO JSONToObj(String JSONString) //Old function name is JSONToObjNew 
{ 
    myDTO deseri = JsonConvert.DeserializeObject<myDTO>(JSONString); 
    return deseri; 
} 

public class myDTO 
{ 
    public myDTO() 
    { 
    } 

    public string StringObject {get; set;} 
} 

Выше мой простой тестовый код, но это дает мне ошибку, когда он запущен Newtonsoft.Json.JsonConvert.SerializeObject (oObject);
