Stopping the task by a cancellation token

[poulad]

Is there a way to send a cancellation token to the task to stop it?

for example:

app.StartTask<SampleTask>(TimeSpan.FromSeconds(15), TimeSpan.FromSeconds(5), source.Token);

Currently - no.

As a fast workaround, you may try to use token.Register with Action that stops task.

In all my use cases I start/stop tasks (a) never (b) only from administration page (during some maintenance).

What is your use case from stopping Task (stopping "forever", because cancellation token is not "undoable") with cancellation token?

@justdmitry My use case is cancelling the task for ever only after some async method(DoSomething()) finishes its job. I'd like to pass the cancellation token from DoSomething method to the task (SampleTask) runner. Then, DoSomething decides on when to stop the task (for ever).
