I have a Blazor Server application (net 7) where a long running background task can be triggered by any user, but once the task has been started everyone must wait until that task is completed.
The users visit a Razor page then leave the page and maybe log-off, but the background task should keep running.
So I need some kind of static background task which updates the UI (via IProgress or something) when someone visits the page and also is only allowed to be triggered once. Sounds like a classic singleton Task, but is that right here?
I know of IHostedService but I don't need a queue of Jobs to be consumed infinitely, only one single task static task running in background and showing each user who visits a Razor page what the current status of the task is.
[Update 1] Just for clarification, it is not a very long running task, still the behavior should be as described.
