title: WCF Client Connection Caching/Pooling
body: <p>Suppose you expose a WCF Service from one project and consume it in another project using 'Add Service Reference' (in this case a Framework 3.5 WPF Application).</p>
  
  <p>Will ClientBase perform any kind of connection pooling of the underlying channel when you re-instantiate a ClientBase derived proxy or will you incur the full overhead of establishing the connection with the service every time? I am especially concerned about this since we are using security mode="Message" with wsHttpBinding.</p>
