ABP Entity Patterns

Domain layer patterns for ABP Framework following DDD principles.

Architecture Layers

Domain.Shared    → Constants, enums, shared types
Domain           → Entities, repositories, domain services, domain events
Application.Contracts → DTOs, application service interfaces
Application      → Application services, mapper profiles
EntityFrameworkCore → DbContext, repository implementations
HttpApi          → Controllers
HttpApi.Host     → Startup, configuration

Key principle: Dependencies flow downward. Application depends on Domain, but Domain never depends on Application.
