Building Microservices with .NET Core 2.0 - Second Edition

Adding a repository

In our monolithic application, we have a common repository throughout the project. In ProductService, by virtue of following all the principals learned up until now, we will create microcomponents, which means separate repositories encapsulating the data layer.

A repository is nothing but a simple C# class that contains the logic to retrieve data from the database and maps it to the model.

Adding a repository is as simple as following these steps:

1. Create a new folder and name it Persistence.
2. Add the IProductRepository interface and a ProductRepository class that will implement the IProductRepository interface.
3. Again, we name the folder Persistence in an effort to follow the general principal for easy identification.
