How to cancel a CancellationToken

Question

I start a task, that start other tasks and so forth.
Given that tree, if any task fails the result of the whole operation is useless. I\'m considering using cancellation tok

Answer 1

A token it gives you the right to know someone is trying to cancel something. It does not give you the right to actually signal a cancellation. Only the cancellation token source gives you that. This is by design.
