Alternative to GetReferencedAssemblies in a PCL

I'm trying to use reflection inside a PCL to recursively find all assemblies referenced in an application.

This is relatively easy to do using the GetReferencedAssemblies() method but unfortunately this isn't available in a PCL.

Is there any alternative or workaround that will achieve the same thing in a PCL? I already have a solution that delegates this to the application using the PCL but it would be nice to have a solution that is self contained with the PCL.
