C# 9 and .NET 5 – Modern Cross-Platform Development - Fifth Edition

By: Mark J. Price

Overview of this book

In C# 9 and .NET 5 – Modern Cross-Platform Development, Fifth Edition, expert teacher Mark J. Price gives you everything you need to start programming C# applications. This latest edition uses the popular Visual Studio Code editor to work across all major operating systems. It is fully updated and expanded with a new chapter on the Microsoft Blazor framework. The book’s first part teaches the fundamentals of C#, including object-oriented programming and new C# 9 features such as top-level programs, target-typed new object instantiation, and immutable types using the record keyword. Part 2 covers the .NET APIs, for performing tasks like managing and querying data, monitoring and improving performance, and working with the file system, async streams, serialization, and encryption. Part 3 provides examples of cross-platform apps you can build and deploy, such as websites and services using ASP.NET Core or mobile apps using Xamarin.Forms. The best type of application for learning the C# language constructs and many of the .NET libraries is one that does not distract with unnecessary application code. For that reason, the C# and .NET topics covered in Chapters 1 to 13 feature console applications. In Chapters 14 to 20, having mastered the basics of the language and libraries, you will build practical applications using ASP.NET Core, Model-View-Controller (MVC), and Blazor. By the end of the book, you will have acquired the understanding and skills you need to use C# 9 and .NET 5 to create websites, services, and mobile apps.
Table of Contents (23 chapters)


There are programming books that are thousands of pages long that aim to be comprehensive references to the C# language and the .NET platform.

This book is different. It is concise and aims to be a brisk, fun read that is packed with practical hands-on walkthroughs of each subject. The breadth of the overarching narrative comes at the cost of some depth, but you will find many signposts to explore further if you wish.

This book is simultaneously a step-by-step guide to learning modern C# proven practices using cross-platform .NET and a brief introduction to the main types of applications that can be built with them. This book is best for beginners to C# and .NET, or programmers who have worked with C# in the past but feel left behind by the changes in the past few years.

If you already have experience with older versions of C#, then in the first topic of Chapter 2, Speaking C#, you can review tables of the new language features and jump straight to them. If you already have experience with older versions of .NET, then in the first topic of Chapter 7, Understanding and Packaging .NET Types, you can review tables of the new platform features and jump straight to them.

I will point out the cool corners and gotchas of C# and .NET, so you can impress colleagues and get productive fast. Rather than slowing down and boring some readers by explaining every little thing, I will assume that you are smart enough to Google an explanation for topics that are related but not necessary to include in a beginner-to-intermediate guide.

If you don't know how, then I provide instructions on how to do this using Visual Studio Code at the end of Chapter 1, Hello, C#! Welcome, .NET!.
