What is repository pattern C# with example?
Repository pattern is one of the preferred patterns to apply in an application because it allows programmers to integrate all of the fundamental data operations related to an entity in one main class. Without this pattern, developers would need to create multiple classes for each entity with the same logic.
What is generic repository pattern in Entity Framework?

What is the right way to include a repository into a controller?
