In Visual Basic and C#, you can call this method as an instance method on any object of type
TaskTSource. When you use instance method syntax to call this method, omit the first parameter. For more information, see
Extension Methods (Visual Basic) or
Extension Methods (C# Programming Guide).
Exceptions Remarks If the antecedent task is cancelled, or faulted with supportsErrors
set to , the status of the antecedent is directly applied to the task
