title: What are WCF Proxies and what are they good for?
body: <p>I have recently been educating myself about WCF and I have even written some production services using WCF. But I have never really looked too much into WCF until recently.</p>
  
  <p>I am aware of the idea of the "proxy" design pattern. I am also aware of the use of a proxy with ASMX web services. But I am having a hard time understanding what a WCF proxy is and how it is used. I have looked thoroughly over the MSDN documentation about WCF, but I am still not grasping the big picture of the use of proxies with WCF services.</p>
