title: Why does MultipartFormDataContent not work when MVC is hosted in Azure?
body: <p>I am having issues with post a form to MVC, but only when the site is hosted inside of azure. When it is hosted locally inside of IIS OR inside of the compute emulator it works fine.</p>
  
  <p>The request is posted, however the fields in the form are not being mapped to the action's parameters.</p>
  
  <p>Is there something funky I need to do with the azure deployment?</p>
  
  <pre><code>MultipartFormDataContent data = new MultipartFormDataContent();
  if (!String.IsNullOrEmpty(about))
  {
      data.Add(new StringContent(about), "about");
  }
  data.Add(new StringContent(displayName), "displayName");
  data.Add(new StringContent(name), "name");
  data.Add(new StringContent(email), "email");
  data.Add(new StringContent(phone), "phone");
  data.Add(new StringContent(isPublic ? "true": "false"), "isPublic");
  data.Add(new StringContent(isPrimary ? "true" : "false"), "isPrimaryProfile");
  if (picture != null)
  {
      byte[] imageBytes = await picture.GetBtyeFromFile();
      string imageString = Convert.ToBase64String(imageBytes);
      data.Add(new StringContent(imageString), "picture");
  }
  
  Uri uri = new Uri(url, UriKind.Absolute);
  HttpResponseMessage responseMessage = await client.PostAsync(uri, data);

  <p>On the server side everything seems to be arriving correctly. Here is the body that I pulled out of the InputStream:</p>
