title: How to put a file in the HttpResponseMessage Content?
body: <p>I want to return a file in an HttpResponseMessage Content something like this:</p>
  
  <pre><code>return Request.CreateResponse(HttpStatusCode.OK, {{a file here}});
  </code></pre>
  
  <p>Or this:</p>
  
  <pre><code>return new HttpResponseMessage() {
     StatusCode = HttpStatusCode.OK;
