Domain-Driven Design with .NET

Domain-Driven Design (DDD) is a strategic and tactical approach to modeling complex business domains as code. In this series, you'll learn how to apply DDD principles directly in C# and .NET, from defining ubiquitous language across teams to architecting scalable enterprise systems with bounded contexts, aggregates, and repositories. Whether you're building microservices or monoliths, DDD helps you organize code around business logic, making systems easier to maintain, test, and evolve as requirements change.

This 10-article series progresses from foundational concepts (what DDD is and why it matters) through core tactical patterns (entities, value objects, aggregates, domain events) to advanced strategies (bounded contexts, anti-corruption layers, and real-world implementation). Each article includes runnable C# examples, design patterns, and practical guidance for .NET developers at all levels.
