## Next Steps for Integration

The implementation is complete and ready for middleware integration:

1. **Middleware Integration** - Update `WireMock.Net.AspNetCore.Middleware` to handle WebSocket upgrade requests
2. **Admin API** - Add endpoints to manage WebSocket mappings
3. **Provider Factory** - Implement response provider factory to create WebSocketResponseProvider when IsWebSocketConfigured is true
4. **Route Handlers** - Add middleware handlers to process WebSocket connections
5. **Testing** - Integration tests with middleware stack
