Dependency Inversion Principle VS Dependency Injection

Understanding the difference between the Dependency inversion principle and the Dependency injection using ASP.NET Core

Dependency Inversion Principle VS Dependency Injection

In the realm of object-oriented programming, the principles of Dependency Inversion (DI) and Dependency Injection (DI) play pivotal roles in achieving maintainable, scalable, and loosely coupled code. In C#, these principles are fundamental for writing robust and testable applications. Let’s delve into these concepts, understand their significance, and explore practical examples in C#.

Dependency Inversion Principle (DIP)

Dependency Inversion is a principle proposed by Robert C. Martin (Uncle Bob) as part of the SOLID principles. It suggests that high-level modules should not depend on low-level modules; both should depend on abstractions. Abstractions should not depend on details; details should depend on abstractions.

In simpler terms, this principle emphasizes:

• Abstraction over concrete implementations: It promotes defining interfaces or abstract classes to decouple high-level modules from low-level implementation details.
• Inverting the direction of dependency: Instead of classes depending directly on…
