Domain-Driven Refactoring

on YouTube ↗01h 01m

" summary

Starts from a procedural “loyalty rewards” handler that loads data, calls an HTTP service, computes values, and saves via EF; applies concrete refactorings (compose/inline methods, extract class, extract interface, use base type, move method to type) with ReSharper and DI changes so the logic moves into OfferType and Member, constructors and private setters enforce invariants, and a domain double dispatch pattern handles async value lookup. Result: behavior lives in domain objects, easier testing and safer mutations.
