- FAQ -

What if bots are red? Ignore this CL. A human will look at errors shortly.

What if the task priority is not set explicitly (no .WithTaskPriority)?
When there is no explicit priority, the priority is inherited from the
calling context (e.g. a task posted from a BACKGROUND task without an
explicit priority will have a BACKGROUND priority).

What if the shutdown behavior is not set explicitly (no .WithShutdownBehavior)?
If shutdown behavior is important for a task, it should be set explicitly.
It's not necessary to specify it if you're fine with either BLOCK_SHUTDOWN
or SKIP_ON_SHUTDOWN.
