Why do we use the repository service pattern?
The Repository-Service Pattern is a great way to architect a real-world, complex application. Each of the layers (Repository and Service) have a well defined set of concerns and abilities, and by keeping the layers separate we can create an easily-modified, maintainable program architecture.
How are unit of work and repository patterns implemented?
The Unit of Work and Repository patterns are intended to encapsulate the infrastructure persistence layer so it is decoupled from the application and domain-model layers. Implementing these patterns can facilitate the use of mock repositories simulating access to the database.
Which is the upper layer of the repository pattern?
The upper layer is the Services. These classes will have Repositories injected to them and can query multiple Repository classes and combine their data to form new, more complex business objects. Further, they introduce a layer of abstraction between the web application and the Repositories so that they can change more independently.
Why should I not use the repository pattern with Entity Framework?
The single best reason to not use the repository pattern with Entity Framework? Entity Framework already implements a repository pattern. DbContext is your UoW (Unit of Work) and each DbSet is the repository. Implementing another layer on top of this is not only redundant, but makes maintenance harder.
What is the difference between a repository and a service layer?
Repository, because it is a typical specified get operation on a single entity set. Service layer, because it orchestrates several operations on several entities. Separate assemblies, so you can add interface implementations from other assemblies without having to reference an assembly that already contains an implementation.
