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.

Summarizing custom type choices

Now that we have covered OOP and the C# features that enable you to define your own types, let's summarize what you've learned.

Categories of custom type and their capabilities

Categories of custom type and their capabilities are summarized in the following table:

Type Instantiation Inheritance Equality Memory
class Yes Single Reference Heap
sealed class Yes None Reference Heap
abstract class No Single Reference Heap
record or record class Yes Single Value Heap
struct or record struct Yes None Value Stack
interface No Multiple Reference Heap

It is best to think about these differences by starting with the "normal" case and then spotting the differences in other cases. For example, a "normal" class can be instantiated with new, it supports single inheritance, it uses memory reference equality, and its state is stored in heap memory.Now let's highlight what is different about the more specialized types...
