To implement domain-driven design in C#, use base classes for aggregate roots, entities, and value objects to encapsulate business logic and enforce invariants. This approach separates your rich domain model from persistence concerns.

A value object in domain modeling represents a domain concept without identity. You can define it in C# using a record type to enforce constraints, such as ensuring a CustomerId contains a non-empty string.

Structure aggregate roots in .NET by encapsulating related entities and enforcing transactional consistency. Define domain events within these aggregates to signal state changes, like an OrderCreated event, ensuring business rules are accurately represented.

Separate your domain model from persistence concerns in .NET when building complex business domains to ensure robust and maintainable software. This separation allows your domain logic to remain independent of database implementation details.

No, domain modeling in C# does not require specific external dependencies. You can implement tactical Domain-Driven Design patterns like repository contracts and aggregates using pure C# code structures without relying on third-party libraries.

The best way to model business invariants within a domain aggregate is to encapsulate state changes within the aggregate root's methods. This ensures all business rules are enforced consistently before any domain events are published.
