From God Service to Clean Domain: A Step-by-Step DDD Refactor in C#

Summary

The video discusses refactoring an overly complex application service by evolving an anemic domain model into a behavior-driven model that encapsulates business logic. The example focuses on an order service with multiple responsibilities like inventory checking, price calculation, and customer credit validation. The key takeaway is to simplify the application service by moving complex business logic into the domain layer, making the code more maintainable, testable, and focused on core orchestration responsibilities.
