title: WCF 4 close client proxy
body: <p>In the old days (.net framework 3.5) we need to be careful to close the WCF client proxies.</p>
  
  <p>In WCF 4 the Close is not available from the client. But it is available inside the proxy.</p>
  
  <pre><code>public class ServiceProxy : System.ServiceModel.ClientBase&lt;IService&gt;, ILoginService
  {
  }
  </code></pre>
  
  <p>Is closing the client proxy no longer required? Or how do we do it?</p>
