s&box

Creates a TaskSource whose entire lifetime is linked to the provided token.
If the token is canceled, all async operations using that TaskSource are canceled.

Example on how this differs from CreateLinkedTokenSource()

var cts = new CancellationTokenSource();
TaskSource ts = TaskSource.Create(cts.Token);

await ts.DelaySeconds(5); // if cts.Token is canceled, ts becomes invalid

var cts = TaskSource.CreateLinkedTokenSource();
TaskSource ts = new TaskSource();

await ts.DelaySeconds(5, cts.Token); // if cts.Token is cancelled only this delay is canceled
await ts.DelaySeconds(5) // Still Valid
