How does it work?

Who knows :)

Xamarin.iOS vs Xamarin.Android

➔ Ahead-of-Time (AOT) compilation in iOS. The program code must be pre-compiled into machine. For this purpose, AOT compiler Mono is used.

➔ Just-in-Time compilation in Android. Code is compiled into some intermediate byte code that is interpreted in CPU instructions at the time of program execution

Xamarin.Android Work

➔ Virtual machine Mono is added to the packaged application

➔ Mono and Dalvik are written on C and are running under the Linux kernel

➔ When starting Android application, both virtual machines start running side by side and they are exchanging data via a special wrapper`s mechanism.

PCL – cross-platform base

➔ PCL code can run on any platform

➔ A small functional

MvvmCross

➔ MVVM template for Xamarin projects

➔ IoC/DI from the box

➔ Wide default functional

➔ Easy to expansion
