Programming in C# 10

Introduction

The book "Programming C# 10" by Ian Griffiths was published in 2022 and immediately became one of the most authoritative guides to the latest version of the C# language and the .NET 6 platform. This is not just another textbook — it is a deep dive into the modern capabilities of C#, written by a recognized expert who participated in the development of the language itself. The book, 738 pages in length, covers all key aspects: from basic syntax to advanced topics such as asynchronous programming, LINQ, reflection, and native code interoperability.

What the book is about

Ian Griffiths consistently guides the reader from the fundamentals to complex concepts. The first part is devoted to the foundation: data types, control constructs, classes, and structures. The author then moves on to object-oriented programming, inheritance, interfaces, and generics. Special attention is paid to the innovations of C# 10: record struct, global using directives, file-scoped namespaces, and improvements in working with pattern matching. The second half of the book covers .NET 6: collections, LINQ, asynchrony, parallel programming, file handling, serialization, reflection, and COM interop. The book concludes with a chapter on Roslyn — the compiler as a service, giving the reader an understanding of the internal workings of C#.

Who this book is for

The book is intended for developers already familiar with the basics of C# (or another C-like language) who wish to deepen their knowledge. Beginners who are just starting to program will find it challenging — the author assumes the reader already understands basic concepts such as variables, loops, and functions. However, for those who want to transition from C# 8/9 to C# 10 or master .NET 6 at a professional level, this is an ideal choice.

What the reader will learn

• Modern C# 10 syntax: record struct, global usings, file-scoped namespaces, improved pattern matching.
• Deep understanding of types: value and reference types, nullable types, Span and Memory.
• Asynchronous programming: async/await, Task, ValueTask, IAsyncEnumerable, channels.
• LINQ and data manipulation: from simple queries to creating custom LINQ providers.
• Parallelism and multithreading: Task Parallel Library, Concurrent Collections, locks and synchronization.
• Reflection and metaprogramming: attributes, runtime code generation, expression trees.
• Roslyn: using the compiler as a service for code analysis and modification.
• Native code interoperability: P/Invoke, COM interop, unsafe code.

Strengths of the book

The first thing that stands out is the depth of exposition. Ian Griffiths does not simply list the language's features but explains why they are designed the way they are, what problems they solve, and how to use them correctly. For example, the chapter on asynchrony is one of the best I have encountered: the author thoroughly examines the memory model, task schedulers, and pitfalls. Second is relevance: the book was published almost simultaneously with the release of .NET 6, so all examples work on the latest version of the platform. Third is practical orientation: each chapter contains numerous code examples that can be tried out immediately. Finally, writing style: Griffiths writes in a lively, clear language, avoiding excessive academicism while not sacrificing precision.

Who it is recommended for

The book will be useful for:

• C# developers who want to update their knowledge to version 10 and .NET 6.
• Java or C++ programmers transitioning to C# — the book will help quickly master the idioms and features
