I need to create service that can handle clients connections and administrator connection.The clients that connects to service are handled by Durable duplex, so the service can send commands to clients in any time when client is connected. When some client
connects, the service should add its callback to clients collection. Then when administrator connects to service he should be able to send some commands to clients. I have created a workflow that is on the image below. In that workflow there is a problem because
any time when the new connection is initialized the client variable is reseted to its default value. How to create static/global variable, or solve a problem in some other way?
