title: How to add <soap:Header> tag? WSDL not appearing with these info
body: <p>I need to add to my message something like this:</p>
  
  <pre><code>  &lt;soap:Header&gt;
      &lt;wsse:Security xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd" soap:mustUnderstand="1"&gt;

          &lt;wsu:Expires&gt;2012-04-22T11:58:30Z&lt;/wsu:Expires&gt;
        &lt;/wsu:Timestamp&gt;
      &lt;/wsse:Security&gt;
    &lt;/soap:Header&gt;

  <p>I'm calling a web service which return a 500 error response which basically means it cannot authenticate I guess cause I'm missing these information from the message, even I have an authentication header on the message. Can this be happening?</p>
  
  <p>How can I add the WS-Security header in the message and add all these info in code?
  I added the service using Add Web Reference in Visual Studio.</p>
  
  <p>Thank you.</p>
