dotnet-domain-modeling

Domain-Driven Design tactical patterns in C#. Covers aggregate roots, entities, value objects, domain events, integration events, domain services, repository contract design, and the distinction between rich and anemic domain models. These patterns apply to the domain layer itself -- the pure C# model that encapsulates business rules -- independent of any persistence technology.

Scope

• Aggregate roots, entities, and value objects
• Domain events and integration events
• Domain services and rich vs anemic model design
