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.

Setting up a class library and console application

We will start by defining a workspace with two projects like the one created in Chapter 5, Building Your Own Types with Object-Oriented Programming. If you completed all the exercises in that chapter, then you can open the Chapter05 workspace and continue working with its projects.

Otherwise, follow the instructions given in this section:

  1. In your existing Code folder, create a folder named Chapter06 with two subfolders named PacktLibrary and PeopleApp, as shown in the following hierarchy:
    • Chapter06
      • PacktLibrary
      • PeopleApp
  2. Start Visual Studio Code.
  3. Navigate to File | Save As Workspace…, enter the name Chapter06, and click Save.
  4. Navigate to File | Add Folder to Workspace…, select the PacktLibrary folder, and click Add.
