Exposing the not-so-secret practices of the cult of DDD
summary
Practical DDD tactics that can be applied today: using value objects as C# records with immutability, value equality and constructor validation to collapse multiple fields into one safer API (example: PersonalDetails and Color records), hiding DB integers in private fields because Entity Framework private field mapping supports it, mapping external models behind an anti‑corruption layer to avoid leaking remote schemas, using aggregate roots as consistency boundaries and the outbox pattern to guarantee events are published reliably — these changes simplify code and reduce bugs in real projects.
