title: debugger is looking for executioncontext.cs, how to fix?
body: <p>I am debugging this code and getting a strange "source not found" page that is looking for this class called ExecutionContext.cs when the debugger lands on the Jtoken line.</p>
  
  <blockquote>
    <p><code>ExecutionContext.cs</code> not found.<br>
    You need to find the <code>ExecutionContext.cs</code> to view the source for the current call stack frame.</p>
  </blockquote>
  
  <p>(see below for additional info)</p>
  
  <pre><code>using Newtonsoft.Json;
  using Newtonsoft.Json.Linq;
  using RestSharp;
  
  IRestResponse content = myApi.GetSomething();
  JToken token = JObject.Parse(content.ToString()); 
  MyClass myclass = token.ToObject&lt;Myclass&gt;();
  </code></pre>
  
  <p>I've also tried replacing Jtoken with dynamic or var and same result.
  I've googled it and there is nothing but the MS documentation which was not helpful in fixing.</p>
  
  <p>Any suggestions on how to get this to execute or at least throw a normal exception I can fix? </p>
  
  <p>Thanks</p>
