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.

Decompiling assemblies

One of the best ways to learn how to code for .NET is to see how professionals do it.

For learning purposes, you can decompile any .NET assembly with a tool like ILSpy. If you have not already installed the ILSpy .NET Decompiler extension for Visual Studio Code, then search for it and install it now:

Good Practice: You could decompile someone else's assemblies for non-learning purposes but remember that you are viewing their intellectual property so please respect that.

  1. In Visual Studio Code, navigate to View | Command Palette… or press Cmd + Shift + P.
  2. Type ilspy and then select ILSpy: Decompile IL Assembly (pick file).
  3. Navigate to the Code/Chapter07/DotNetCodeEverywhere/bin/Release/net5.0/osx-x64 folder.
  4. Select the System.IO.FileSystem.dll assembly and click Select assembly.
  5. In the EXPLORER window, expand ILSPY DECOMPILED MEMBERS, select the assembly, and note the two edit windows that open...
