Create a service class to handle business logic and interact with the database. Here is an example defining both the interface and the class for it (we’ll use these interfaces in a second): using MyMicroservice.DBContext; namespace MyMicroservice.Services; public interface IProductService {...
Let us understand how to create an interface of type T. A blank interface will look like this. publicinterfaceITest<T>{} An interface with one member function definition publicinterfaceITest<T>{List<T>GetList();} The syntax for multiple generic values for an interface publicinterfaceITest<T,U...
