C# 12 and .NET 8 – Modern Cross-Platform Development Fundamentals - Eighth Edition

4.6 (14)
By: Mark J. Price

Overview of this book

This latest edition of the bestselling Packt series will give you a solid foundation to start building projects using modern C# and .NET with confidence. You'll learn about object-oriented programming; writing, testing, and debugging functions; and implementing interfaces. You'll take on .NET APIs for managing and querying data, working with the fi lesystem, and serialization. As you progress, you'll explore examples of cross-platform projects you can build and deploy, such as websites and services using ASP.NET Core. This latest edition integrates .NET 8 enhancements into its examples: type aliasing and primary constructors for concise and expressive code. You'll handle errors robustly through the new built-in guard clauses and explore a simplified implementation of caching in ASP.NET Core 8. If that's not enough, you'll also see how native ahead-of-time (AOT) compiler publish lets web services reduce memory use and run faster. You'll work with the seamless new HTTP editor in Visual Studio 2022 to enhance the testing and debugging process. You'll even get introduced to Blazor Full Stack with its new unified hosting model for unparalleled web development flexibility.

Introducing the C# language

This part of the book is about the C# language—the grammar and vocabulary that you will use every day to write the source code for your applications.

Programming languages have many similarities to human languages, except that in programming languages, you can make up your own words, just like Dr. Seuss!

In a book written by Dr. Seuss in 1950, If I Ran the Zoo, he states this:

“And then, just to show them, I’ll sail to Ka-Troo And Bring Back an It-Kutch, a Preep, and a Proo, A Nerkle, a Nerd, and a Seersucker, too!”

C# language versions and features

This part of the book covers the C# programming language and is written primarily for beginners, so it covers the fundamental topics that all developers need to know, including declaring variables, storing data, and how to define your own custom data types.

This book covers features of the C# language from version 1 up to the latest version, 12.

If you already have some familiarity with older versions of C# and are excited to find out about the new features in the most recent versions of C#, I have made it easier for you to jump around by listing language versions and their important new features below, along with the chapter number and topic title where you can learn about them.

Understanding C# standards

Over the years, Microsoft has submitted a few versions of C# to standards bodies, as shown in Table 2.1:

C# version

ECMA standard

ISO/IEC standard

1.0

ECMA-334:2003

ISO/IEC 23270:2003

2.0

ECMA-334:2006

ISO/IEC 23270:2006

5.0

ECMA-334:2017

ISO/IEC 23270:2018

6.0

ECMA-334:2022

ISO/IEC 23270:2022

Table 2.1: ECMA standards for C#

The ECMA standard for C# 7.3 is still a draft. So don’t even think about when C# versions 8 to 12 might be ECMA standards! Microsoft made C# open source in 2014. You can read the latest C# standard document at the following link: https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/specifications.

More practically useful than the ECMA standards are the public GitHub repositories for making the work on C# and related technologies as open as possible, as shown in Table 2.2:
