Thanks for the reply. My queue names depend on the current system configuration, which can change from time to time, so can’t be constants. Specifically the queues represent which tenants that server is responsible for, and that’s stored in a database. I’ve considered making an IOptions to represent that configuration, and define it’s source from a database. But it feels quite difficult to do all that inside ConfigureServices and ensure it’s available before the call to AddHangfireServer.
