Book Description

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.

Who this book is for

This book is for beginners as well as intermediate-level C# and .NET programmers who have worked with C# in the past and want to catch up with the changes made in the last few years.

Prior exposure to C# or .NET is not a prerequisite. A general understanding of programming will help you to work through the book more comfortably, though the content is suitable for those completely new to programming.

If you already have some C# and .NET skills and want to focus on developing practical apps, you can pick up Mark's other .NET book, Apps and Services with .NET 8, instead.
