title: How can work WinForm client with WCF session?
body: <p>I have a distribuited application with WinForm client connected to WCF services.
  Currently I don't use the session.
  I want tu use session, because application have a login, operations and logout.</p>
  
  <p>In WCF side  I have this code</p>
  
  <pre><code>[ServiceContract]
  public interface IOperationsUser
  {
  
      [OperationContract]
      User login(User loginUsers);
  
      *****
  }
  </code></pre>
  
  <p>In client side I use this  way </p>
  
  <pre><code>private OperationsUser WCF_OPERATIONS_USER =  new OperationsUser ();
  </code></pre>
  
  <p>and so call methods</p>
  
  <pre><code>User userLogin = WCF_OPERATIONS_USER.login(myUser)
  </code></pre>
  
  <p>How can I use session for each user ?</p>
