What is Repository pattern and how it will be implemented?
The Repository pattern implements separation of concerns by abstracting the data persistence logic in your applications. This data store can be a database, an xml file, etc. You can apply this design pattern to even hide how data that is exposed by a web service or an ORM is accessed.
When should you use Repository pattern?
The Repository pattern makes it easier to test your application logic. 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.
Why does Entity Framework use the repository pattern?
The Primary reason, being that as of Entity Framework Core, entity Framework is already an implementation of the Repository Pattern.
Which is an example of the repository pattern?
In this example, we are going to implement a very simple repository pattern based as an abstraction over Entity Framework core, primarily because historically this has been the most popular use of the Repository pattern. This serves to highlight the constituent parts of the repository pattern.
How to implement repository pattern in ASP.NET Core?
Create IRepository interface under the Data folder with the following code: This interface is planned to be an abstraction layer over different ORMs. Now, we will create an abstract class for EF Core which implements this interface. Create EFCore folder in the Data folder and add EfCoreRepository class here with the following code:
Is the repository and unit of work pattern the same?
Taking a high-level view of an ORM, such as Entity Framework (EF), one might conclude that it is nothing more than an implementation of the Repository Pattern and a Unit of Work Pattern, and you would be right, It is, and it does provide an abstraction for interacting with the database.
