The book "Programming C# 12" by Ian Griffiths is considered one of the most comprehensive and detailed guides to modern C# and the .NET 8 platform. The author explains the language not superficially but with regard to real-world industrial development scenarios, including cloud services, web applications, and desktop systems.
The main feature of this manual is its systematic approach. Griffiths thoroughly explains all the key capabilities of C#: from types and collections to asynchronous programming, LINQ, Rx, memory management, and efficient multithreading. At the same time, he does not limit himself to theory - he provides practical code examples and explains when to use new features and when to rely on proven solutions.
What New and Useful Knowledge Will You Gain From This Book?
Reading it provides not only a review of C# syntax but also an understanding of the philosophy behind its evolution. The author emphasizes how to properly use the innovations of the latest versions (C# 11 and 12), including generics math, new pattern matching and polymorphism features, improvements in memory handling, and asynchronous programming.
- New language features: primary constructors, collection expressions, extended patterns.
- Practical applications of generics, including generics math and operator interfaces.
- A modern approach to asynchronous programming and working with threads.
- Using LINQ and Rx to process sequences and events.
- Detailed guidance on memory management, including
Span<T>,Memory<T>, andReadOnlySequence<T>. - Multithreading analysis: Task, Parallel LINQ, TPL Dataflow.
- Architectural approaches for cloud-native applications.
- Tools for diagnostics, testing, and code optimization.
Who Should Definitely Study This Book?
The book is aimed at developers who already have programming experience and want to master C# at a deep level.
- Experienced developers from other languages - will quickly adapt to the .NET ecosystem, master CLR features, and use its rich libraries.
- Enterprise engineers - will learn to design large-scale cloud and distributed systems with performance and security requirements in mind.
- Desktop and web application developers - will gain ready-to-use practices for building flexible architectures in ASP.NET Core and .NET MAUI.
- Those working with high-load systems - the book provides in-depth explanations of memory management, asynchrony, and parallel computations.
Thus, the book is not a beginner’s manual but a practical reference for professionals seeking to advance to a new level of working with C#.
Where and How Are the Book’s Insights Applied in Practice?
The knowledge gained can be applied across all areas of C# development. Developers will be able to build cloud services on .NET 8 using ASP.NET Core, create web APIs, integrate databases, and scale solutions in containers. For desktop applications, the book teaches the use of Windows Presentation Foundation and .NET MAUI.
In high-performance applications, insights into generics math and memory management help optimize algorithms for processing large datasets. For financial and analytical systems, the chapters on LINQ, Rx, and parallel computations are especially valuable. In short, the book prepares developers for tasks of any complexity: from writing small tools to designing enterprise-level cloud systems.
More About the Author of the Book
The Developer's Opinion About the Book
Unlike short reference books, this one covers not only syntax but also the language’s philosophy, strengths, and best practices. I found the chapters on generics and LINQ especially useful, as these mechanisms enable writing more expressive and flexible code in real projects. The author carefully explains how to use the new features of C# 12, such as generics math, and when it’s better to stick to older constructs for stability and compatibility.
The book’s strengths are its systematic approach and level of detail. It is not a beginner’s manual but a working tool for professionals. The drawback is its density: some chapters require thoughtful reading and revisiting. Nonetheless, it is truly considered a desk reference for engineers who want to build industrial-grade applications - from cloud services to desktop solutions.

FAQ for "Programming C# 12"
1. How does "Programming C# 12" differ from previous editions?
The new edition incorporates the features of C# 12 and .NET 8. It covers generics math, updated pattern matching, new polymorphism mechanisms, as well as CLR optimizations for cloud and containerized scenarios. The book has been significantly revised, with many examples rewritten to reflect modern practices.
2. Can beginners in C# use this manual?
The author assumes the reader already has a grasp of basic programming concepts. For absolute beginners, the book may be too difficult. However, for developers coming from Java, C++, or Python, it serves as an excellent transitional guide: comparisons and explanations allow for quick adaptation.
3. Is the book suitable for learning ASP.NET Core and .NET MAUI?
Yes, it explains the modern capabilities of .NET for web and client applications in detail. While it is not a dedicated ASP.NET Core textbook, it provides the fundamental language and library knowledge necessary for confident use of these frameworks.
4. How does the book assist in cloud application development?
Special attention is given to performance, asynchrony, threading, and memory management - essential for cloud applications where scalability and resource efficiency are critical. It also describes .NET 8 features for containerization and distributed environments.
5. Does the book cover testing and debugging tools?
Yes. The author explores unit testing, the use of Visual Studio, Rider, and VS Code, working with the .NET SDK, as well as built-in diagnostics and profiling tools. This makes the book a practical guide for the entire development lifecycle.
6. How relevant is the knowledge described in the book?
It is fully up-to-date with the latest versions of the language and platform: C# 12 and .NET 8. These versions are LTS releases, ensuring relevance for years to come. Thus, the knowledge in the book is applicable in today’s real-world projects and will remain so at least until the end of .NET 8’s support period.
