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.

Fixing bugs in code is expensive. The earlier that a bug is discovered in the development process, the less expensive it will be to fix.

Unit testing is a good way to find bugs early in the development process because they test a small unit before they are integrated together or are seen by user acceptance testers. Some developers even follow the principle that programmers should create unit tests before they write code, and this is called Test-Driven Development (TDD).

Microsoft has a proprietary unit testing framework known as MSTest. There is also a framework named NUnit. However, we will use the free and open-source third-party framework xUnit.net. All three do basically the same thing. xUnit was created by the same team that built NUnit, but they fixed the mistakes they felt they made previously. xUnit is more extensible and has better community support.
