Task.ContinueWith Method (Action(Task))
Creates a continuation that executes asynchronously when the target Task completes.
Assemblies: System.Threading.Tasks (in System.Threading.Tasks.dll)
mscorlib (in mscorlib.dll)
The continuationAction argument is a null reference (Nothing in Visual Basic).
The returned Task will not be scheduled for execution until the current task has completed, whether it completes due to running to completion successfully, faulting due to an unhandled exception, or exiting out early due to being canceled.
The following example defines a task that populates an array with 100 random date and time values. It uses the method to select the earliest and the latest date values once the array is fully populated.
Because a console application may terminate before the continuation task executes, the Wait() method is called to ensure that the continuation finishes executing before the example ends.
For an additional example, see Chaining Tasks by Using Continuation Tasks.
