Cancelling Parallel.For(Each)

[VladiStep]

Is it necessary to call po.CancellationToken.ThrowIfCancellationRequested() if it throws (and then catches) the same OperationCanceledException anyway?

Hi @VladiStep - thank you for posting this issue. This is code is intentional. It shows the reader what exception results from the invocation to ThrowIfCancellationRequested.

Okay, I got it.
I just think there should be some note about the fact that it would work without ThrowIfCancellationRequested(), because For()/ForEach() already does that.
