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 .NET components

.NET is made up of several pieces, which are as follows:

  • Language compilers: These turn your source code written with languages such as C#, F#, and Visual Basic into intermediate language (IL) code stored in assemblies. With C# 6.0 and later, Microsoft switched to an open source rewritten compiler known as Roslyn that is also used by Visual Basic.

    More Information: You can read more about Roslyn at the following link:

  • Common Language Runtime (CoreCLR): This runtime loads assemblies, compiles the IL code stored in them into native code instructions for your computer's CPU, and executes the code within an environment that manages resources such as threads and memory.
  • Base Class Libraries (BCLs) of assemblies in NuGet packages (CoreFX): These are prebuilt assemblies of types packaged and distributed using NuGet for performing common tasks when building applications...
