title: How to get HttpContent from Request object?
body: <p>If a caller adds HttpContent:</p>
  
  <pre><code>using (var content = new MultipartFormDataContent()) 
  {
    HttpContent additionalContent = StringContent("just a test");
    content.Add(additionalContent);
  </code></pre>
  
  <p>Which is then POST'ed, how does the receiver retrieve this additional content? </p>
  
  <p>I've seen examples where people call Request.Content. However, HttpContent.Current.Request doesn't have a Content object.</p>
  
  <p>The receiver is an <code>[HttpPost]</code> WebAPI.</p>
