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 app models for C# and .NET

Since this book is about C# 9 and .NET 5, we will learn about app models that use them to build the practical applications that we will encounter in the remaining chapters of this book.

More Information: Microsoft has extensive guidance for implementing App Models such as ASP.NET web applications, Xamarin mobile apps, and UWP apps in its .NET Application Architecture Guidance documentation, which you can read at the following link: https://www.microsoft.com/net/learn/architecture

Building websites using ASP.NET Core

Websites are made up of multiple web pages loaded statically from the filesystem or generated dynamically by a server-side technology such as ASP.NET Core. A web browser makes GET requests using URLs that identify each page and can manipulate data stored on the server using POST, PUT, and DELETE requests.

With many websites, the web browser is treated as a presentation layer, with almost all of the processing...
