When implemented in a derived class, runs logic to cause graceful early completion of the activity.
protected virtual void Cancel(
The execution context in which the activity executes.
The following code sample demonstrates using Cancel in a class that inherits from NativeActivity<TResult>. This example is from the Non-generic ParallelForEach sample.
protected override void Cancel(NativeActivityContext context)
// If we don't have a completion condition then we can just
// use default logic.
if (this.CompletionCondition == null)
