GetActivityTask API action and respond using SendTask*
API actions. This function lets Step Functions know the existence of your activity
and returns an identifier for use in a state machine and when polling from the activity.
CreateActivity is an idempotent API. Subsequent requests won’t create a duplicate
resource if it was already created. CreateActivity's idempotency check is based
on the activity name. If a following request has different tags values,
Step Functions will ignore these differences and treat it as an idempotent request
of the previous. In this case, tags will not be updated, even if they are different.
This is an asynchronous operation using the standard naming convention for .NET 4.5 or higher. For .NET 3.5 the operation is implemented as a pair of methods using the standard naming convention of BeginCreateActivity and EndCreateActivity.
