├── EnterpriseAgent.Infrastructure/  # External concerns
├── EnterpriseAgent.API/            # Web API presentation
└── EnterpriseAgent.Tests/          # Comprehensive test suites

CQRS Pattern

  • Commands: Modify state through well-defined operations
  • Queries: Read state without side effects
  • Events: Communicate changes across boundaries

Domain-Driven Design

  • Aggregates: Consistency boundaries
  • Value Objects: Immutable domain concepts
  • Domain Events: Business-meaningful occurrences
  • Repositories: Abstract data persistence
