Hi! The Xafari Server interacts with the client via the Message Queue. A single Message Queue is stored in a database of a client application. Clients generate new Messages to the Queue, and the Xafari Server process these Messages. ![null](https://galaktika-soft.com/wp-content/uploads/2018/01/xafari_server_1.png) To learn more about Xafari Server and Message Queue, refer to documentation. We do not have a working example of using Xafari with DevExpress XAF WCF. If you need any further assistance on this subject, please feel free to reactivate this ticket.
