To get the most out of this book

The majority of the chapters can be read independently of each other and in any order. But to get the most out of this book, I recommend that you read the chapters in the order presented. As you work through the chapters, follow the instructions, and carry out the tasks presented. Then, when you reach the end of a chapter, answer the questions and carry out the recommended further reading to reinforce what you have learned. For maximum benefit when working through the contents of this book, it is recommended that you meet the following requirements:

Software/hardware covered in the book	Requirements

It will be useful if you have these in place before you start reading and working your way through the chapters.

If you are using the digital version of this book, we advise you to type the code yourself or access the code via the GitHub repository (link available in the next section). Doing so will help you avoid any potential errors related tothe copying and pasting of code.

You should have basic experience of using Visual Studio 2019 Community Edition or higher, and basic C# programming skills, including writing console applications. Many examples will be in the form of C# console applications. The main project will be using ASP.NET. It will help if you are capable of writing ASP.NET websites using the framework and core. But don't worry – you will be guided through the steps that you need to go through.
