title: SignalR 2.0.0 beta2 IJsonSerializer extensibility
body: <p>I want to add some custom serialization logic so that the converted json contains camel case properties. </p>
  
  <p>For that reason i tried to replace the default IJsonSerializer with one the i found in this link:</p>
  
  <p><a href="https://github.com/SignalR/SignalR/issues/500" rel="noreferrer">https://github.com/SignalR/SignalR/issues/500</a></p>
  
  <p>However there seems to be a problem. More specifically, the <code>JsonNetSerializer</code> and <code>IJsonSerializer</code> classes do not exist in any of the signalR assemblies. Is there any change that happened to the recent version of signalR  in that respect?</p>
