Domain-Driven Refactoring
summary
Shows how to refactor a realistic .NET loyalty app step‑by‑step: break a giant handler into named methods, extract an IOfferValueCalculator and inject it, replace a primitive enum with Steve Smith’s SmartEnum to host expiration logic, and push assignment behavior into the Member entity so the model gains methods instead of just data. Uses Mediator-style handlers, ReSharper refactorings, constructor DI, and inner strategy classes to untangle anemic models and make the domain testable and encapsulated. extract methods into named steps OfferValueCalculator via interface replace enum with SmartEnum-based strategy move assign logic into Member entity
