# Tutorial 7: Shared Support Helpers

When building many workflows for the same domain (e.g., 50+ policy change workflows), extract reusable components into a support helper class.

## What to Extract

| Component | Example |
|-----------|---------|
| **Address constants** | `LegacyRabbitAddress`, `HttpAddress` — centralized routing |
| **Workflow references** | `WorkflowReference` — for SubWorkflow/ContinueWith targets |
| **Payload builders** | Static methods returning `WorkflowExpressionDefinition` |
| **State initializers** | Base state + override pattern |
| **Flow extensions** | Extension methods on `WorkflowFlowBuilder<T>` for common sequences |
