Why can't you make a reference from a universal Windows 10 application to a classic class library? I know that you must use a universal Windows 10 class library for Windows 10 applications, but is there a class library that can have references to all types of applications or programs?
I need to do this because I have began with a WPF program (WishLister.Client.Wpf) and made references to WishLister.Client.Data and WishLister.Client.Models. But now I will made a reference from WishLister.Client.Uwa to the class libraries Data and Models, but Visual Studio is unable to do that.
Is there a way to solve it?
