Book Description
Learn 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.
