Type: System.Threading.Tasks.TaskScheduler

The TaskScheduler to associate with the continuation task and to use for its execution.

Return Value

Type: System.Threading.Tasks.Task(Of TResult)
A new continuation Task(Of TResult).


The continuationFunction argument is Nothing.

The provided CancellationToken has already been disposed.

The returned Task(Of TResult) will not be scheduled for execution until the current task has completed. If the criteria specified through the continuationOptions parameter are not met, the continuation task will be canceled instead of scheduled.
