When I try to install AutoMapper 5.0.2 in a PCL Profile 111 which is using package.config I get the error below:
Could not install package 'System.Runtime.InteropServices.RuntimeInformation 4.0.0'. You are trying to install this package into a project that targets '.NETPortable,Version=v4.5,Profile=Profile111', 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.

In order to install AutoMapper I'm forced to use the new project.json in my PCL
But I can't because it is not yet supported by Xamarin Studio (and I need Xamarin Studio to compile for iOS)
