Xamarin has unfortunately muddled their branding.

Xamarin Forms is not Xamarin, it is a DSL. You do not need to use it. At its core Xamarin is c# with pinvoke to the underlying native platform implementation. You'll still need that platform knowledge but now you can share the core business logic between platforms.

To get maximum code share you'll need a MVVM framework such as ReactiveUI which is based on the Reactive Extensions and modeled on functional reactive principals check out https://github.com/reactiveui/ReactiveUI/releases/tag/7.0.0 or http://reactiveui.net

Agreed, people seem to think Xamarin == Xamarin Forms, while the real power lies in shared business logic with native UIs, in my opinion.

Xamarin Forms may be useful for internal super-CRUD LOB apps that really are just a collection of input fields, but as soon as you do anything customer facing, you should be using the standard native UI approach.

Also +1 for ReactiveUI, it completely changed the way I build apps for the better.
