Nice to see an alternative nuget package for dependancy injection thanks, personally I use MVVMLight, but I can see this as an alternative.

However why on earth is your example using PCL shared project ?

Xamarin has moved on from PCL shared projects years ago — using .netstandard is the way to do it since then, and the templates in both Visual Studio on Windows and Mac provide ample options for this ?

PCL is dead — long live .netstandard
