I have a SignalR hub, the goal is to monitor the progress of a long running job (several hours) and as it progresses everyone monitoring the progress gets updates.
What I'm trying to do is figure out the best way to send a message to a SignalR without being 'connected' to it as a client.
I've been trying to search docs to see if there's a way to inject SignalR into another controller or class just to send messages without being 'connected'... but I'm not seeing anything.
Just inject typed hubcontext.
Details see here: Call SignalR Core Hub method from Controller
