What do you do when you want to create testable code or when you need to access native features? You need an interface to implement! Then you need a way to inject that implementation (dependency) to access it from your shared code (or anywhere). You will do this pretty often with mobile application development and luckily for us Xamarin.Forms has it all built in! Today' we take a look at Dependency Injection for Xamarin.Forms to create testable services and also access native features.
