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.

Internationalizing your code

Internationalization is the process of enabling your code to run correctly all over the world. It has two parts: globalization and localization.

Globalization is about writing your code to accommodate multiple languages and region combinations. The combination of a language and a region is known as a culture. It is important for your code to know both the language and region because the date and currency formats are different in Quebec and Paris, despite them both using the French language.

There are International Organization for Standardization (ISO) codes for all culture combinations. For example, in the code da-DK, da indicates the Danish language and DK indicates the Denmark region, and in the code fr-CA, fr indicates the French language and CA indicates the Canadian region.

ISO is not an acronym. ISO is a reference to the Greek word isos (which means equal).

Localization is about customizing the user interface to support a language...
