title: How to convert List to observablecollection
body: <p>Hi all I have a Json class as shown below:</p>
  
  <pre><code>private class RootObject
  {
      public string flag { get; set; }
      public string message { get; set; }
      public Result result { get; set; }
  }
  
  public class Result
  {
      public List&lt;List&lt;string&gt;&gt; professions { get; set; }
  }
  </code></pre>
