Introduction: Implementing Interfaces and Inheriting Classes

This section focuses on creating new types from existing ones using object-oriented programming (OOP). You will learn about generics, which help make your code safer and more performant. You will explore delegates and events for exchanging messages between types. You will understand the differences between reference types and value types, implement interfaces to provide common functionality, and create derived classes that inherit from base classes to reuse functionality. You'll also learn how to override inherited members and apply polymorphism. In addition, you will learn how to create extension methods, cast between classes in an inheritance hierarchy, and improve your code quality using static code analyzers.

This section covers the following topics:
