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.

Native ahead-of-time compilation

Native AOT produces assemblies that are:

  • Self-contained, meaning they can run on systems that do not have the .NET runtime installed.
  • Ahead-of-time (AOT) compiled to native code, meaning a faster startup time and a potentially smaller memory footprint.

Native AOT compiles IL code to native code at the time of publishing, rather than at runtime using the Just In Time (JIT) compiler. But native AOT assemblies must target a specific runtime environment like Windows x64 or Linux Arm.Since native AOT happens at publish time, you should remember that while you are debugging and live working on a project in your code editor, it is still using the runtime JIT compiler, not native AOT, even if you have AOT enabled in the project! However, some features that are incompatible with native AOT will be disabled or throw exceptions, and a source analyzer is enabled to show warnings about potential code incompatibilities.

Limitations of native AOT
