What is Entity Framework Code?
It’s an Entity Framework feature. Code First adds a model builder that inspects your classes that the context is managing, and then uses a set of rules or conventions to determine how those classes and the relationships describe a model, and how that model should map to your database. All of this happens at runtime.
What is Entity Framework used for?

Why are you all doing Entity Framework wrong?
Features pop into existence seemingly at random depending which minor version you’re working on.
Is the Entity Framework an abstraction for the storage mechanism?
It’s not and neither is EF an abstraction for the storage mechanism it relies upon. It is instead a set of common APIs that let us access data in a uniform way. This is not an abstraction for the very reasons I just stated in that we can not deny or mitigate the behavior of the underlying implementation in any way.
