	Func<Task<TAntecedentResult>[], TResult> continuationFunction,
	CancellationToken cancellationToken,
	TaskContinuationOptions continuationOptions,
	TaskScheduler scheduler
)

Parameters

tasks
Type: System.Threading.Tasks.Task<TAntecedentResult>[]

The array of tasks from which to continue.

continuationFunction
Type: System.Func<Task<TAntecedentResult>[], TResult>

cancellationToken
Type: System.Threading.CancellationToken

The cancellation token that will be assigned to the new continuation task.

continuationOptions
