This guide offers .NET developers insights into creating robust, maintainable, and flexible web applications using C# 9 and .NET 5, focusing on effective application of design patterns. It begins with foundational design patterns and architectural principles, including dependency injection and ASP.NET Core mechanisms. The content is structured to progress from component-scale patterns to application-scale techniques, enabling a comprehensive understanding of software structure. Key design patterns from the GoF, such as strategy, singleton, decorator, facade, and composite, are explored. The chapters are organized by scale and topic, facilitating a gradual build-up of knowledge akin to program development. Use cases illustrate how to combine design patterns, enhancing comfort with various approaches. The book also covers essential concepts like the SOLID principles for flexible software, .NET 5 dependency injection, MVC patterns for web APIs, and clean architecture principles.
