Overview of this book

This latest edition of the bestselling Packt series will give you a solid foundation to start building projects using modern C# and .NET with confidence. You'll learn about object-oriented programming; writing, testing, and debugging functions; and implementing interfaces. You'll take on .NET APIs for managing and querying data, working with the fi lesystem, and serialization. As you progress, you'll explore examples of cross-platform projects you can build and deploy, such as websites and services using ASP.NET Core. This latest edition integrates .NET 8 enhancements into its examples: type aliasing and primary constructors for concise and expressive code. You'll handle errors robustly through the new built-in guard clauses and explore a simplified implementation of caching in ASP.NET Core 8. If that's not enough, you'll also see how native ahead-of-time (AOT) compiler publish lets web services reduce memory use and run faster.

This chapter is about deriving new types from existing ones using object-oriented programming (OOP). You will learn how to use operators as an alternative method to implement simple functionality, and you will learn how to use generics to make your code safer and more performant. You will learn about delegates and events to exchange 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. Finally, you will learn how to create extension methods and cast between classes in an inheritance hierarchy.This chapter covers the following topics:

  • Setting up a class library and console application
  • Static methods and overloading operators
  • Making types safely...
