We're implementing our business logic in a Xamarin.Forms PCL. There is no UI whatsoever, it's just a set of interfaces exposing async methods, with the implementation inside. We're effectively using Xamarin.Forms as the limiting envelope so our code and carefully selected libraries will run on Android, iOS, WinPhone, PC, etc.
What we want to do is take that PCL project, which currently appears to compile in the /Debug directory as a .dll, and produce native libraries from it, each one to be included in a corresponding native application where the UI will be developed. Obviously Xamarin already does this linking in some way when it generates the native binaries for the full solution. How can we do that linking ourselves?
