TaskFactory Constructor (CancellationToken, TaskCreationOptions, TaskContinuationOptions, TaskScheduler)

Initializes a new instance of the TaskFactory class with the specified configuration.

Namespace:  System.Threading.Tasks
Assembly:  mscorlib (in mscorlib.dll)

public TaskFactory(
	CancellationToken cancellationToken,
	TaskCreationOptions creationOptions,
	TaskContinuationOptions continuationOptions,
	TaskScheduler scheduler


Type: System.Threading.CancellationToken
The default cancellation token that will be assigned to tasks created by this TaskFactory unless another cancellation token is explicitly specified while calling the factory methods.
Type: System.Threading.Tasks.TaskCreationOptions
The bitwise combination of the default enumeration values to use when creating tasks with this task factory.

Type: System.Threading.Tasks.TaskContinuationOptions
A bitwise combination of the default enumeration values to use when creating continuation tasks with this task factory.

Type: System.Threading.Tasks.TaskScheduler
The default scheduler to use for any tasks created with this task factory. A null value indicates that Current should be used.


The creationOptions argument specifies an invalid value.

With this constructor, the TaskCreationOptions property is initialized to creationOptions, the TaskContinuationOptions property is initialized to continuationOptions, and the TaskScheduler property is initialized to scheduler, unless it's null, in which case the property is initialized to the current scheduler (see Current).
