Clean Architecture with .NET

Learn Clean Architecture as a set of organizing principles, not just code templates. This book shows how to design scalable, testable .NET apps using modern patterns, DDD, CQRS, and secure Azure integration. Free with your book: DRM-free PDF version + access to Packt's next-gen Reader* Key FeaturesArchitect robust .NET apps with domain-driven, testable Clean ArchitectureIntegrate Azure External ID and Key Vault with real-world casesApply MediatR, CQRS, and modern .NET practices to streamline architectureImplement persistence with EF Core using a code-first approach and Clean Architecture boundariesPurchase of the print or Kindle book includes a free PDF eBookBook DescriptionLearn how to apply Clean Architecture in real-world .NET applications with Azure in this guide. Designed around an e-commerce project - Project Odyssey, you'll design and build every architectural layer, from core domain logic and application orchestration to infrastructure and presentation. This book equips you to apply DDD, CQRS, MediatR, and dependency injection, enabling loosely coupled, testable systems. You'll build reusable and modular code structures that scale with your application's complexity and learn how to persist data using EF Core with a code-first approach, managing schema evolution with migrations while keeping infrastructure concerns isolated from your domain logic. Learn how to develop secure systems by integrating Azure External ID, Azure Key Vault, and application-level authentication and authorization. Gain practical experience with Blazor Server, Razor components, and MudBlazor UI, all integrated within a layered architecture. Learn to enforce business logic boundaries, reduce boilerplate with generic request handlers, and use real-world use cases like payment processing and shopping cart management. Whether you're new to Clean Architecture or scaling up enterprise solutions, this book provides the patterns, tools, and mindset to succeed. *Email sign-up and proof of purchase required What you will learnDesign scalable .NET applications with Clean Architecture principlesStructure core logic using use cases, CQRS, and domain modelingIntegrate Azure External ID, Key Vault, and secure service configurationsUse EF Core with a code-first approach to manage database schemas and persistenceApply MediatR and FluentValidation for streamlined workflowsBuild rich UIs using Blazor Server and MudBlazorBuild scalable multi-host applications with structured, transparent service compositionReduce architectural boilerplate while maintaining structureWho this book is for.NET developers, software engineers, and solution architects who want to build applications that are easier to understand, test, and evolve over time. This book is a good fit if you're already familiar with C# and .NET, and want a clearer, more practical way to structure real-world applications using Clean Architecture. Basic knowledge of web development and Azure will help you follow along.
