Domain-Driven Design (DDD) helps you model complex business rules by defining clear consistency boundaries, expressing domain concepts as validated value objects, and using domain events to decouple side effects from core invariants.
Load the ddd skill when implementing DDD for a .NET domain and design an aggregate root with validated value objects and domain events to represent your business workflow.

Aggregate roots in .NET serve as single entry points enforcing invariants. You raise domain events inside aggregates and dispatch them after persistence, decoupling side effects from core domain logic.
You need bounded contexts and aggregate consistency boundaries when complex business rules require strict transactional invariants within a single aggregate while allowing eventual consistency across multiple aggregates.
Implement value objects with strongly-typed IDs in C# using immutable records with built-in validation. This replaces primitive obsession and ensures correct equality and behavior for domain concepts.
The best way to persist aggregates is using a repository-per-aggregate-root pattern. This boundary saves the entire aggregate as a whole, preventing invalid states from external code directly modifying child entities.
Domain-driven design works for decoupling side effects by raising domain events inside aggregates. Side effects are handled after persistence or transaction completion, keeping the domain model focused on invariants.
External code should only interact through the aggregate root to maintain business rules and prevent invalid states. Directly accessing child entities bypasses the consistency boundaries and breaks invariants.
