Design Patterns in C# 15 (Paperback)

Paperback. Write C# software that is easier to extend, test, and maintain-without adding patterns your application does not need.Knowing a pattern's name is not the same as knowing when to use it. Mastering Design Patterns: Practical architecture with C# 14 and .NET 10 connects the classic patterns to the decisions developers face as requirements change: how to create objects, separate responsibilities, manage behavior, and preserve clear contracts.Across 29 chapters, you will explore all 23 Gang of Four design patterns, plus Object Pool. C# implementations, application examples, diagrams with Mermaid source, practical exercises, and tradeoff discussions help you understand both the structure of a pattern and the problem it is meant to solve.Inside, you will learn to: Apply object-oriented and SOLID principles to define clearer responsibilities and more useful abstractions.Choose among creational, structural, and behavioral patterns instead of treating every design problem alike.Follow a recurring fictional commerce application through checkout, pricing, export, and fulfillment scenarios.Evaluate lifetimes, mutable state, ownership, and failure cases before adapting an example.Connect patterns with generics, LINQ, concurrency, thread safety, and reflection.Bring several patterns together in an integrated checkout workshop.Recognize when a constructor, a delegate, or a small switch is simpler than another abstraction.Who this book is forDevelopers who already understand basic C# methods, collections, and control flow and want to strengthen their software-design skills. The opening chapters refresh the object-oriented foundations needed for the examples; this is not a first introduction to programming.The examples distinguish teaching implementations from production infrastructure, making their limits part of the lesson rather than hiding them.Go beyond memorizing a catalog. Learn to choose, implement, and question design patterns with confidence. This item is printed on demand.
