You should not use TaskCreationOptions.LongRunning in your case. I would use Parallel.For.

The LongRunning option is not to be used if you're going to create a lot of tasks, just like in your case. It is to be used for creating couple of tasks that will be running for a Long Time.

By the way, i never used this option in any similar scenario.
