Azure Websocket Timeouts on Long-Living Connections November 10, 2020 By Nick Proud

I’ve been recently working on a gateway service hosted in Azure that is primarily a TCP server. One of the key requirements of the project is that it allows clients running a desktop-based windows service to initiate a handshake over TCP when their respective service is started, and then keeps a connection open between the client and server for the receipt of messages at any given time. However, this presented a problem. Azure doesn’t like me doing this.
