7 Composition and Object Collaboration

A practical guide to using composition, collaboration, and delegation in object-oriented design, including how to choose between composition and inheritance.
Study guide · Updated

4 Inheritance

A practical guide to modeling inheritance hierarchies, reusing and overriding behavior, applying polymorphism, and choosing composition when it produces a safer design.
Study guide · Updated

6 Interfaces and Abstract Types

Learn how interfaces and abstract classes define contracts, support polymorphism, invert dependencies, and enable replaceable implementations in object-oriented design.
Study guide · Updated

8 Object-Oriented Design

A practical guide to designing object-oriented systems by assigning responsibilities, controlling dependencies, applying abstractions thoughtfully, and balancing flexibility with simplicity.
Study guide · Updated

5 Polymorphism

A practical guide to using polymorphism in C#, including dynamic dispatch, type relationships, substitutability, abstraction-based design, and composition.
Study guide · Updated

2 Classes and Objects

A clear introduction to how object-oriented programs use classes, objects, state, methods, initialization, identity, and lifecycles to model systems.
Study guide · Updated

3 Encapsulation and Abstraction
