System.Threading.Tasks Namespace

[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]

The System.Threading.Tasks namespace provides types that simplify the work of writing concurrent and asynchronous code. The main types are System.Threading.Tasks.Task which represents an asynchronous operation that can be waited on and cancelled, and System.Threading.Tasks.Task<TResult>, which is a task that can return a value. The Factory class provides static methods for creating and starting tasks, and the System.Threading.Tasks.TaskScheduler class provides the default thread scheduling infrastructure.

Public classConcurrentExclusiveSchedulerPairProvides task schedulers that coordinate to execute tasks while ensuring that concurrent tasks may run concurrently and exclusive tasks never do.
Public classTaskRepresents an asynchronous operation.
Public classTask<TResult>Represents an asynchronous operation that can return a value.
Public classTaskCanceledExceptionRepresents an exception used to communicate task cancellation.
Public classTaskCompletionSource<TResult>Represents the producer side of a Task<TResult> unbound to a delegate, providing access to the consumer side through the Task property.
Public classTaskExtensionsProvides a set of static (Shared in Visual Basic) methods for working with specific kinds of Task instances.
Public classTaskFactoryProvides support for creating and scheduling Task objects.
Public classTaskFactory<TResult>Provides support for creating and scheduling Task<TResult> objects.
Public classTaskSchedulerRepresents an object that handles the low-level work of queuing tasks onto threads.
Public classTaskSchedulerExceptionRepresents an exception used to communicate an invalid operation by a TaskScheduler.
Public classUnobservedTaskExceptionEventArgsProvides data for the event that is raised when a faulted Task's exception goes unobserved.

Public enumerationTaskContinuationOptionsSpecifies the behavior for a task that is created by using the ContinueWith() or ContinueWith() method.
Public enumerationTaskCreationOptionsSpecifies flags that control optional behavior for the creation and execution of tasks.
Public enumerationTaskStatusRepresents the current stage in the lifecycle of a Task.
