Your first application with Xamarin.Forms
![How the DependencyService Works ?
There are three parts to a DependencyService implementation:
Interface - An Interface in the shared code that defines the
functionality that requires platform-specific code.
Registration - An implementation of the Interface in each platform-
specific application project, along with an assembly attribute that
'registers' the class so that the DependencyService can create
instances of it.
[assembly:Dependency(typeof(className))]
Location - calling DependencyService.Get<>() in shared code to
get a platform-specific instance of the Interface at run time, thereby
allowing the shared code to access the underlying platform.](https://image.slidesharecdn.com/xamarinforms-150323075621-conversion-gate01/85/Your-first-application-with-Xamarin-Forms-8-320.jpg)
