title: Cannot Convert List to Json
body: <p>I have the following action method:</p>
  
  <pre><code>public class MyDeviceController : ApiController
  {
      // GET api/&lt;controller&gt;
      public JsonResult Get()
      {
          int userId = -1;
          List&lt;String&gt; myDevices1 = new List&lt;String&gt;();
          myDevices1.Add("1");
          &gt;&gt; return Json(myDevices1); &lt;&lt; Error here           
      }
  }
  </code></pre>
  
  <p>The return is underlined red with the following error:</p>
  
  <pre><code>cannot implicitly convert type (JsonResult to List&lt;string&gt;)
  </code></pre>
  
  <p>I am using Asp.net Web Api. I think its getting confused between the using System.web.http and System.mvc.http
