The SOLID principles are a set of five key design principles for building maintainable and flexible software architecture: Single Responsibility, Open/Closed, Liskov Substitution, Interface Segregation, and Dependency Inversion. The post details each principle with examples in C#, providing guidelines to help keep classes focused and testable, favoring abstraction and composition over inheritance, and ensuring extensibility without modifying existing code.
