title: Problem with nullable types in .NET WS client
body: <p>I've WebService written in Java that has method </p>
  
  <pre><code>@WebMethod    
  public void createUser(Long id, String name)
  {
  
  }
  </code></pre>
  
  <p>Now I want to use this method in .NET client. I think I should be able to use this method with nullable long but I can't. Is there any annotation or maybe some other way to force .NET use nullable types?</p>
  
  <p>I think that if in java I use Long (not long) so it's natural that in .NET  I'll have method with nullable parameter</p>
