C# 8.0 and .NET Core 3.0 – Modern Cross-Platform Development - Fourth Edition

By: Mark J. Price

Overview of this book

In C# 8.0 and .NET Core 3.0 – Modern Cross-Platform Development, Fourth 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 new chapters on Content Management Systems (CMS) and machine learning with ML.NET. The book covers all the topics you need. Part 1 teaches the fundamentals of C#, including object-oriented programming, and new C# 8.0 features such as nullable reference types, simplified switch pattern matching, and default interface methods. Part 2 covers the .NET Standard APIs, such as managing and querying data, monitoring and improving performance, working with the filesystem, async streams, serialization, and encryption. Part 3 provides examples of cross-platform applications you can build and deploy, such as web apps using ASP.NET Core or mobile apps using Xamarin.Forms. The book introduces three technologies for building Windows desktop applications including Windows Forms, Windows Presentation Foundation (WPF), and Universal Windows Platform (UWP) apps, as well as web applications, web services, and mobile apps.

Introducing .NET Core 3.0

This part of the book is about the functionality in the APIs provided by .NET Core 3.0, and how to reuse functionality across all the different .NET platforms using .NET Standard. .NET Core 2.0 and later's support for a minimum of .NET Standard 2.0 is important because it provides many of the APIs that were missing from the first version of .NET Core. The 15 years' worth of libraries and applications that .NET Framework developers had available to them that are relevant for modern development have now been migrated to .NET Core and can run cross-platform on macOS and Linux variants, as well as on Windows. For example, API support increased by 142% from .NET Core 1.1 to .NET Core 2.0.

.NET Standard 2.1 adds about 3,000 new APIs. Some of those APIs need runtime changes that would break backwards compatibility, so .NET Framework 4.8 only implements .NET Standard 2.0. .NET Core 3.0, Xamarin, Mono, and Unity implement .NET Standard 2.1.
