Overview of this book

Extensively revised to accommodate all the latest features that come with C# 10 and .NET 6, this latest edition of our comprehensive 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. The book covers the .NET APIs for performing tasks like managing and querying data, monitoring and improving performance, and working with the filesystem, async streams, and serialization. You’ll build and deploy cross-platform apps, such as websites and services using ASP.NET Core. Instead of distracting you with unnecessary application code, the first twelve chapters will teach you about C# language constructs and many of the .NET libraries through simple console applications. In later chapters, having mastered the basics, you’ll then build practical applications and services using ASP.NET Core, the Model-View-Controller (MVC) pattern, and Blazor.

Talking about OOP

An object in the real world is a thing, such as a car or a person, whereas an object in programming often represents something in the real world, such as a product or bank account, but this can also be something more abstract.

In C#, we use the class (mostly) or struct (sometimes) C# keywords to define a type of object. You will learn about the difference between classes and structs in Chapter 6, Implementing Interfaces and Inheriting Classes. You can think of a type as being a blueprint or template for an object.

The concepts of OOP are briefly described here:

  • Encapsulation is the combination of the data and actions that are related to an object. For example, a BankAccount type might have data, such as Balance and AccountName, as well as actions, such as Deposit and Withdraw. When encapsulating, you often want to control what can access those actions and the data, for example, restricting how the internal state of an object can be accessed or...
