How Xamarin works across platforms

Xamarin and unity should be my next recent development, ready to start researching how Xamarin works across platforms.

Xamarin has been popular for a while, looking at a lot of information, but most of it is about building the environment, the relationship between Mono and Xamarin.

This is how it is described today on Xamarin's official website, where share speaks its true meaning. There are also some comments on the Internet as to what level of share can be reached. Most of the ideas are support for business logic layer sharing.

Interface layer can not be shared, perhaps because the interface is implemented in different ways, after all, the interface in addition to the code there are many definition files and resource files. Now at least you can use C # to implement functionality, very much!
