Overview of this book

Extensively revised to accommodate the latest features that come with C# 11 and .NET 7, this latest edition of our guide will get you coding in C# with confidence. You’ll learn object-oriented programming, writing, testing, and debugging functions, implementing interfaces, and inheriting classes. Next, you’ll take on .NET APIs for performing tasks like managing and querying data, working with the filesystem, and serialization. As you progress, you’ll also explore examples of cross-platform projects you can build and deploy, such as websites and services using ASP.NET Core. Instead of distracting you with unnecessary graphical user interface code, the first eleven chapters will teach you about C# language constructs and many of the .NET libraries through simple console applications. Having mastered the basics, you’ll then start building websites, web services, and browser apps. By the end of this book, you’ll be able to create rich web experiences and have a solid grasp of object-oriented programming that you can build upon.
