title: WebService RequestSoapContext property not found
body: <p>I have a asp.net website in visual studio 2013. I added a webservice. I need to send authentication parameter (username and password) as SOAP header. But it cannot find the property RequestSoapContext.</p>
  
  <p>I added using Microsoft.Web.Services3; in my code.</p>
  
  <pre><code>CCWS.Service proxy = new CCWS.Service();
  UsernameToken userToken = new UsernameToken("", "", PasswordOption.SendPlainText);
  proxy.RequestSoapContext.Security.Tokens.Add(token);
  </code></pre>
  
  <p>Some forum says to change reference type in reference.cs file. But I cannot find any such file in my solution.
  Can anyone please help?</p>
