    Hi Alessandro, Any Json its throwing the above exception, the sample code is like below

                var response = "{\"id\": 0, \"name\": \"sinol\"}";
                Model.SampleJson result = JsonConvert.DeserializeObject<Model.SampleJson>(response);
                Debug.WriteLine("Response String is >> " + result.ToString());
