Design-Patterns

TL;DR DIP means depend on abstractions, not concrete implementations. Use interfaces and dependency injection to decouple business logic from details. DIP improves testability, flexibility, and maintainability in C# code. Avoid leaky abstractions, unnecessary interfaces, and service locator anti-patterns. Use C# 12 primary constructors and .NET 8 DI features for clean, modern architecture. The Dependency Inversion Principle helps you turn rigid, tightly-coupled code into flexible, testable systems. Rather than depending on concrete implementations, your high-level modules rely on abstractions. This goes beyond dependency injection, it’s about changing the direction of control flow. ...

Learn why experienced C# developers choose interfaces over abstract classes 95% of the time. Real-world examples, team benefits, and clean architecture tips.

Polymorphism isn’t just a language feature, it’s a way to build systems that are easier to extend, change, and maintain. Learn how polymorphism powers design patterns like Template Method, Strategy, and Visitor in C#.

Discover how composition helps you follow the SOLID principles in C#. See practical examples for each principle, learn why composition is more flexible than inheritance, and get actionable tips for writing robust, testable, and maintainable code.

Discover why composition is often a better choice than inheritance in C#. This article explains the drawbacks of deep inheritance, demonstrates how to use composition for flexible and maintainable code, and provides practical tips for applying these principles in real-world projects. Includes code examples and guidance for testable, scalable software design.
