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.

Publishing your applications for deployment

There are three ways to publish and deploy a .NET application. They are:

  1. Framework-dependent deployment (FDD).
  2. Framework-dependent executables (FDEs).
  3. Self-contained.

If you choose to deploy your application and its package dependencies, but not .NET itself, then you rely on .NET already being on the target computer. This works well for web applications deployed to a server because .NET and lots of other web applications are likely already on the server.

Sometimes, you want to be able to give someone a USB stick containing your application and know that it can execute on their computer. You want to perform a self-contained deployment. While the size of the deployment files will be larger, you'll know that it will work.

Creating a console application to publish

Let's explore how to publish a console application:

  1. Create a new console application project named DotNetCoreEverywhere...
