title: What PCL Profiles does Autofac 4 support?
body: <p>We're using Autofac 3.5.2 in a PCL of ours (Profile259) and Nuget tells us that version 4.1 is available, but when we attempt to update it Nuget fails with the message:</p>
  
  <p>"You are trying to install this package into a project that targets 'portable-net45+win+wpa81+wp80+MonoTouch10+MonoAndroid10+xamarinmac20+xamarintvos10+xamarinwatchos10+xamarinios10', but the package does not contain any assembly references or content files that are compatible with that framework. For more information, contact the package author." </p>
  
  <p>Has anyone been able to get Autofac 4.1 working in any PCL profile?</p>
  
  <p>Thanks!
