The Liskov Substitution Principle (LSP) is a design principle that ensures substitutability of objects in a program. It emphasises that derived classes (subtypes) should be substitutable for their base classes…

The Interface Segregation Principle
Introduction The Interface Segregation Principle (ISP) is a design principle that promotes modularity and flexibility. It emphasises creating specific, focused interfaces that cater to the needs of different clients rather…
The State Pattern
Introduction The State Pattern allows an object to alter its behaviour when its internal state changes. This pattern promotes flexibility and adaptability in C# code by encapsulating behaviour within internal…
The Facade Pattern
Introduction The Facade Pattern is a tool for simplifying complex systems, promoting flexibility, and improving maintainability in C# code. This pattern provides a simplified interface to a complex system, hiding…
Design Patterns
Introduction Object-oriented programming (OOP) has revolutionized software development, providing a structured and modular approach to creating complex applications. Within OOP, design patterns are blueprints for solving everyday problems and achieving…
The Proxy Pattern
Introduction The Proxy Pattern controls access to objects, promoting flexibility and abstraction in C# code. This pattern introduces a surrogate object, known as a proxy, that acts as an intermediary…
The Memento Pattern
Introduction The Memento Pattern is a tool for preserving and restoring the state of an object, promoting flexibility and undo/redo operations. This pattern captures and externalises an object's internal state,…
The Flyweight Pattern
Introduction The Flyweight Pattern is a tool for efficiently creating and managing many similar objects, promoting resource utilisation and code reusability. This pattern encapsulates common attributes in a shared pool,…
The Decorator Pattern
Introduction The Decorator Pattern is a tool for dynamically modifying the behaviour of objects at runtime, promoting flexibility and reusability. This pattern allows for attaching additional responsibilities to objects without…
The Composite Pattern
Introduction The Composite Pattern is a tool for representing hierarchical structures of objects, promoting flexibility and maintainability. This pattern allows for treating individual objects and objects' compositions uniformly, enhancing code…
