  <p>by using classes generated from json2csharp like this</p>
  
  <pre><code>public class ObjPatientData
      {
          public class Device
          {
              public string serial { get; set; }
              public string manufacturer { get; set; }
              public string model { get; set; }
              public string first_value_at { get; set; }
              public string last_value_at { get; set; }
              public string supports_glucose { get; set; }
              public string supports_cgm { get; set; }
              public string supports_insulin { get; set; }
              public string supports_carb { get; set; }
          }
  
          public class PatientData
          {
              public Device device { get; set; }
              public List&lt;object&gt; data { get; set; }
          }
  
          public class RootObject
          {
              public List&lt;PatientData&gt; PatientData { get; set; }
          }
  
      }
  </code></pre>
  
  <p>and calling it like this:</p>
  
  <pre><code>LPatientData = new List&lt;ObjPatientData.RootObject&gt;();
  LPatientData = JsonConvert.DeserializeObject&lt;List&lt;ObjPatientData.RootObject&gt;&gt;(Json);
  </code></pre>
  
  <p>but I get a list of empty objects; any help will be appreciated.</p>
  
  <p>Thanks!
  please note that </p>
