DependencyService not needed for SQLite anymore?

Hello.

I was looking at the "ToDo" sample app (https://github.com/xamarin/xamarin-forms-samples/tree/master/Todo) and noticed that the SQLiteAsyncConnection is created in the "Core" application and does not use "DependencyService", nor is there an implementation for each platform (Android, iOS, UWP).

Is this the new way to implement SQLite, and when did it change?

Thanks in advance,

Mike
