title: how to use protobuf-net in the xamarin ios pcl
body: <p>I am trying to use protobuf-net with the new xamarin ios pcl, and it's nuget packet doesn't appear to support the framework. Is there a way to import protobuf-net into the pcl?</p>
  
  <p>Update:
  I just found recompiling the PCL with the new Xamarin PCL definitions allowed the resulting library to be references. Nice work! Let me know when a new version is posted to Nuget.</p>
