To implement aggregate roots and entities in C#, design entities with unique identity and build aggregate roots that manage domain events and enforce invariants within the domain layer.

A rich domain model encapsulates business logic within entities and aggregate roots, while an anemic model uses data structures with logic in external services, and choosing between them involves understanding these architectural trade-offs.

To create immutable value objects in C#, define objects strictly by their attributes rather than identity, ensuring data integrity and expressiveness without leaking persistence concerns into the domain layer.

To decouple domain logic in .NET, define and dispatch domain events within aggregate roots to trigger side effects, keeping business rules encapsulated independently from persistence technologies.

Define repository contracts by creating clear interfaces for data access within the domain layer, ensuring the domain remains independent of underlying persistence technologies and database implementations.

Use Domain-Driven Design tactical patterns when building complex .NET applications like e-commerce platforms, to correctly model aggregates, value objects, and events so business rules are strictly enforced.
