When to use repository and unit of work?

When to use repository and unit of work?

When the controller runs under a unit test class, it receives a repository that works with data stored in a way that you can easily manipulate for testing, such as an in-memory collection. Later in the tutorial you’ll use multiple repositories and a unit of work class for the Course and Department entity types in the Course controller.

Is the Rep / UOW pattern useful with Entity Framework?

EF Core already implements a Rep/UoW pattern, so layering another Rep/UoW pattern on top of EF Core isn’t helpful. A better solution is to use EF Core directly, which allows you to use all of EF Core’s feature to produce high-performing database accesses. What people are saying about the Rep/UoW pattern with EF.

How to include business logic in a repository?

You can include business logic in your repository or restrict it to data access logic. You can also build an abstraction layer into your database context class by using IDbSet interfaces there instead of DbSet types for your entity sets.

Which is the best tool for UOW implementation?

Using tools like EFCore gives us DBContext which already represents repository and UoW (Unit Of Work) implementation with very minimal effort. The best thing is you can use DBContext anywhere from your code.

What’s the difference between Rep / UOW and EF Core?

For instance, a Rep/UoW would update an entity using the EF Core’ Update method, which save every property in the entity. Whereas, using EF Core’s built-in change tracking features it will only update the properties that have changed. Too generic: “The more reusable the code is, the less usable it is.”

Why do you need a repository for infrastructure?

The Repository pattern allows you to easily test your application with unit tests. Remember that unit tests only test your code, not infrastructure, so the repository abstractions make it easier to achieve that goal.

How are repository patterns used in infrastructure persistence layer?

The Repository pattern 1 Define one repository per aggregate. 2 Enforce one aggregate root per repository. 3 The Repository pattern makes it easier to test your application logic. 4 The difference between the Repository pattern and the legacy Data Access class (DAL class) pattern. 5 Repositories shouldn’t be mandatory.

When to instantiate a repository in a controller?

When you instantiate the repository in your controller, you’ll use the interface so that the controller will accept a reference to any object that implements the repository interface. When the controller runs under a web server, it receives a repository that works with the Entity Framework.
