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.

Understanding Blazor

In Chapter 14, Introducing Practical Applications of C# and .NET, I introduced you to Blazor (and SignalR that is used by Blazor Server). Blazor is supported on all modern browsers.

Understanding Blazor hosting models

As a reminder, Blazor is a single app model with two main hosting models:

  • Blazor Server runs on the server side, so the C# code that you write has full access to all resources that your business logic might need without needing to authenticate. It then uses SignalR to communicate user interface updates to the client side. The server must keep a live SignalR connection to each client and track the current state of every client, so Blazor Server does not scale well if you need to support lots of clients. It first shipped as part of .NET Core 3...
