Implementing Interfaces and Inheriting Classes

This chapter is about deriving new types from existing ones using object-oriented programming (OOP). You will learn about generics and how they make your code safer and more performant. You will learn about delegates and events for exchanging messages between types. You will see the differences between reference and value types. You will implement interfaces for common functionality. You will create a derived class to inherit from a base class to reuse functionality, override an inherited type member, and use polymorphism. You will learn how to create extension methods and how to cast between classes in an inheritance hierarchy. Finally, you will learn how to write better code with the help of static code analyzers.

This chapter covers the following topics:

• Setting up a class library and console application
• Making types safely reusable with generics
• Raising and handling events
• Implementing interfaces
