Parameters

task

Type: System.Threading.TasksTaskTSource
The antecedent task.

continuationFunction

Type: SystemFuncTaskTSource, Task
The continuation function to execute when task completes. The continuation function returns a Task which provides the final result of the continuation.

supportsErrors

Type: SystemBoolean
if the continuationFunction properly handles a faulted antecedent task; otherwise, .

Type Parameters

TSource

The type of the result produced by the antecedent TaskTResult.

Return Value

Usage Note

If the antecedent task is cancelled, or faulted with supportsErrors set to , the status of the antecedent is directly applied to the task returned by this method; it is not wrapped in an additional AggregateException.

Notes to Callers
Since the continuationFunction is executed synchronously, this method should only be used for lightweight continuation functions. This restriction applies only to continuationFunction itself, not to the Task returned by it.
