title: Use WebClient with socks proxy
body: <p>Is there any way to use a socks proxy with <code>WebClient</code>? Specifically with the <code>DownloadString</code> method that it provides?  </p>
  
  <p>I don't want to use any third party stuff like privoxy, freecap whatever and I can't use commercial libraries like those from Chilkat. I tried using stuff from <a href="http://www.mentalis.org/" rel="noreferrer">http://www.mentalis.org/</a> in fact I used their <code>WebRequest</code> implementation but they don't seem to have something similar for WebClient.</p>
