📚 SOLID Principles in C# – Correct vs Incorrect Implementations

This project demonstrates the five SOLID principles of object-oriented design in C# through clear, side-by-side examples. Each principle is organized into its own folder, containing both Incorrect (violating the principle) and Correct (properly applying the principle) implementations.

🎯 What are SOLID Principles?

SOLID is an acronym for five design principles that make software designs more understandable, flexible, and maintainable:

• S - Single Responsibility Principle
• O - Open/Closed Principle
• L - Liskov Substitution Principle
• I - Interface Segregation Principle
• D - Dependency Inversion Principle
