title: Empty content on the downloaded PDF using itextsharp in WebAPI 2 response
body: <pre><code>public IHttpActionResult DownloadPDF()

      return ResponseMessage(new HttpResponseMessage

  }
  Here is the CreatePdf method:
  
  private Stream CreatePdf()
  {
      using (var document = new Document(PageSize.A4, 50, 50, 25, 25))
      {
          var output = new MemoryStream();
  
          var writer = PdfWriter.GetInstance(document, output);
          writer.CloseStream = false;
  
          document.Open();
          document.Add(new Paragraph("Hello World"));
          document.Close();
  
          output.Seek(0, SeekOrigin.Begin);
  
          return output;
      }
  }
  </code></pre>
