Provides types that simplify the work of writing concurrent and asynchronous code. The main types are Task, which represents an asynchronous operation that can be waited on and cancelled, and Task, which is a task that can return a value. The TaskFactory class provides static methods for creating and starting tasks, and the TaskScheduler class provides the default thread scheduling infrastructure.
Classes
| ConcurrentExclusiveSchedulerPair | Provides task schedulers that coordinate to execute tasks while ensuring that concurrent tasks may run concurrently and exclusive tasks never do. |
|---|---|
| Parallel | Provides support for parallel loops and regions. |
| ParallelLoopState | Enables iterations of parallel loops to interact with other iterations. An instance of this class is provided by the Parallel class to each loop; you can not create instances in your code. |
| ParallelOptions | Stores options that configure the operation of methods on the Parallel class. |
| Task | Represents an asynchronous operation. |
| Task | Represents an asynchronous operation that can return a value. |
| TaskAsyncEnumerableExtensions | Provides a set of static methods for configuring Task-related behaviors on asynchronous enumerables and disposables. |
| TaskCanceledException | Represents an exception used to communicate task cancellation. |
| TaskCompletionSource | Represents the producer side of a Task unbound to a delegate, providing access to the consumer side through the Task property. |
| TaskCompletionSource | Represents the producer side of a Task unbound to a delegate, providing access to the consumer side through the Task property. |
| TaskExtensions | Provides a set of static methods for Task. |
| TaskFactory | Provides support for creating and scheduling Task objects. |
| TaskFactory | Provides support for creating and scheduling Task objects. |
| TaskScheduler | Represents an object that handles the low-level work of queuing tasks onto threads. |
| TaskSchedulerException | Represents an exception used to communicate an invalid operation by a TaskScheduler. |
| TaskToAsyncResult | Provides methods for using Task to implement the Asynchronous Programming Model pattern based on "Begin" and "End" methods. |
| TimeProviderTaskExtensions | Provide extensions methods for Task operations with TimeProvider. |
| UnobservedTaskExceptionEventArgs | Provides data for the event that is raised when a faulted Task's exception goes unobserved. |
