Object-oriented programming (OOP) is a programming paradigm organized around objects rather than actions, and data rather than logic. With the newest release of C#, there are a number of new additions that improve OOP. This book aims to teach OOP in C# in an engaging and interactive way. After going through the book, y ou will have an understanding of the four pillars of OOP, which are encapsulation, inheritance, abstraction, and polymorphism, and be able to leverage the latest features of C# 8.0, such as Nullable Reference Types and Asynchronous Streams. You will then explore various design patterns, principles, and best practices in OOP.

This book is intended for people who are new to OOP. It assumes that you already have basic C# skills. No knowledge of OOP in any other language is expected.

, Overview of C# as a Language, covers a basic overview of the C# programming language to enable the beginner to understand the language constructs. The chapter will also explain why .NET exists as a framework and how to utilize the .NET framework in programs. The chapter will conclude by introducing Visual Studio as an editor for developing C# projects.

, Hello OOP - Classes and Objects , explains the most basic concepts of object-oriented programming. We start by explaining what a class is and how to write a class.
