TaskFactory.StartNew Method

Creates and starts a Task.

This member is overloaded. For complete information about this member, including syntax, usage, and examples, click a name in the overload list.

Starting with the .NET Framework 4.5, the Task.Run method is the recommended way to launch a compute-bound task. Use the StartNew method only when you require fine-grained control for a long-running, compute-bound task. This includes scenarios in which you want to control the following:

  • Task creation options. Tasks created by the Task.Run method by default are created with the TaskCreationOptions.DenyChildAttach option. To override this behavior, or to provide other TaskCreationOptions options, call a StartNew overload.

  • Parameter passing. The overloads of the Task.Run method do not allow you to pass a parameter to the task delegate. Overloads of the StartNew method do.

  • The task scheduler. The overloads of the Task.Run method use the default task scheduler. To control the task scheduler, call a StartNew overload with a scheduler parameter. For more information, see Task Schedulers.
