Remarks

Completion releases the execution callback and cancellation resources. The handle keeps the result available for later waits.

Methods

Cancel()

Requests execution cancellation, or cancels pending work without invoking it. Completed work is unaffected.

public void Cancel()

Remarks

Await WaitAsync(CancellationToken) to observe completion, including asynchronous cleanup in the callback.

Exceptions

AggregateException

A callback registered with the work's cancellation token throws.

WaitAsync(CancellationToken)

Waits until the entire callback, including asynchronous finally blocks and code after InvokeAsync, has finished using screen resources.

public Task WaitAsync(CancellationToken waitCancellationToken = default)

Parameters

waitCancellationToken CancellationToken

Cancels only this wait, without canceling execution.

Returns

Task

A task carrying the callback's success, failure, or cancellation after its resource use has ended.

Exceptions

InvalidOperationException

A lifecycle callback or this work attempts to wait for the work.
