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.

Working with spans, indexes, and ranges

One of Microsoft's goals with .NET Core 2.1 was to improve performance and resource usage. A key .NET feature that enables this is the Span<T> type.

Using memory efficiently using spans

When manipulating arrays, you will often create new copies or subsets of existing ones so that you can process just the subset. This is not efficient because duplicate objects must be created in memory.If you need to work with a subset of an array, use a span because it is like a window into the original array. This is more efficient in terms of memory usage and improves performance. Spans only work with arrays, not collections, because the memory must be contiguous.Before we look at spans in more detail, we need to understand some related objects: indexes and ranges.

Identifying positions with the Index type

C# 8 introduced two features for identifying an item's index position within an array and a range of items using two indexes.You learned...
