title: CefSharp 3 set proxy at Runtime
body: <p>I downloaded CEF (chromuim embedded framework) binary distributation that comes with (cefclient &amp; cefsimple) c++ examples, And Realized that cefclient can change proxy settings on run-time.</p>
  
  <p>And the key to do that is to Grab the RequestContext and call the function SetPreference.</p>
  
  <p>on CefClient all works just nice.</p>
  
  <p>but on CefSharp calling SetPreference always returns false, and also HasPreference returns false for the preference name "proxy".</p>
