Assembly:  mscorlib (in mscorlib.dll)

public enum TaskCreationOptions

Member nameDescription
NoneSpecifies that the default behavior should be used.
PreferFairnessA hint to a TaskScheduler to schedule a task in as fair a manner as possible, meaning that tasks scheduled sooner will be more likely to be run sooner, and tasks scheduled later will be more likely to be run later.
LongRunningSpecifies that a task will be a long-running, coarse-grained operation involving fewer, larger components than fine-grained systems. It provides a hint to the TaskScheduler that oversubscription may be warranted. Oversubscription lets you create more threads than the available number of hardware threads.
AttachedToParentSpecifies that a task is attached to a parent in the task hierarchy. For more information, see Nested Tasks and Child Tasks.
