How do I abort/cancel TPL Tasks?

Question

In a thread, I create some System.Threading.Task and start each task.

When I do a .Abort() to kill the thread, the tasks are not aborted.

Answer 1

Like this post suggests, this can be done in the following way:

int Foo(CancellationToken token)
{
    Thread t = Thread.CurrentThread;
    using (token.Register(t.Abort))
    {
        // compute-bound work here
    }
}

Although it works, it's not recommended to use such approach. If you can control the code that executes in task, you'd better go with proper handling of cancellation.
