title: Adding PCL library project as a Reference to xamarin project
body: <p>I've created a core PCL library which can be used in both the xamarin.android,xamarin.iOS projects. I've been creating a xamarin package by using that PCL  ,which I am going to upload into the xamarin component store as a library component.How should I add that PCL library for my xamarin.android/iOS sample projects to compile.Either as a DLL Reference or as a whole PCL project,so xamarin.component.exe can make the proper reference in xamarin package?</p>
