# Domain Events - Accumulation Pattern (C#)

## Purpose
Enable clean domain models by accumulating events within aggregates and delegating publishing to infrastructure components.

## Rules and Guidelines
- ✅ **DO**: Collect events in aggregates, publish via infrastructure after persistence
- ✅ **DO**: Ensure transactional consistency between state changes and events
- ✅ **DO**: Clear events after successful publishing
- ❌ **DON'T**: Publish events before persistence
- ❌ **DON'T**: Let domain models depend on infrastructure
