The started task.
Calling TaskFactory.StartNew(Action) is functionally equivalent to creating a task by using one of its constructors, and then calling the Task.Start method to schedule the task for execution. Starting with the net_v45, you can use the erload:System.Threading.Tasks.Task.Run method with an stem.Action object as a quick way to call erload:System.Threading.Tasks.TaskFactory.StartNew with default parameters.
