So, I got the following

{StatusCode: 200, ReasonPhrase: 'OK', Version: 1.1, Content: System.Net.Http.StreamContent, Headers:
{
  Pragma: no-cache
  Cache-Control: no-cache
  Date: Mon, 21 Nov 2016 13:50:34 GMT
  Server: Microsoft-IIS/8.5
  X-AspNet-Version: 4.0.30319
  X-Powered-By: ASP.NET
  Content-Length: 792
  Content-Type: application/json; charset=utf-8
  Expires: -1
}}

In the fiddler I do not see what I got - may be I filtered too much? I see my request but don't see the response.
