title: Add Portable Class Library (in DLL form) to Xamarin Studio
body: <p>I have built a Portable Class Library with Visual Studio 2012 that will also build in Xamarin Studio. I would like to add the DLL built from that PCL (from the bin directory of the solution) to an existing (Android app) project in Xamarin Studio 5.3. </p>
  
  <p>I notice that according to documentation from Xamarin, this is generally possible. For example, from <a href="http://developer.xamarin.com/guides/cross-platform/application_fundamentals/pcl/introduction_to_portable_class_libraries/">this page</a>:</p>
  
  <blockquote>
    <p>The output from a PCL (ie. the resulting assembly DLL) can also be added as a reference to most projects. This makes PCL an ideal way to ship cross-platform components and libraries.</p>
  </blockquote>
  
  <p>If I simply right click in the solution tree and add the file, this does not seem to be usable by the project.</p>
  
  <p>What is the correct way to add this resulting DLL based on a PCL to my Xamarin project?</p>
