title: Invoking a WCF service using claims based authentication
body: <p>I have a WCF service deployed in a server machine. We are using claims based authentication to authenticate the WCF service caller. The WCF service is restricted by using IIS Authorization rules.</p>
  
  <p>How do I programmatically invoke the WCF service using .NET? The client app uses a proxy generated using SVCUtil.   calling the service reads the credentials from a configuration file (not the app.config file, in fact the client application does not have a *.config file).</p>
