Deregisters the specified task definition by family and revision. Upon deregistration,
the task definition is marked as INACTIVE. Existing tasks and services that
reference an INACTIVE task definition continue to run without disruption. Existing
services that reference an INACTIVE task definition can still scale up or down
by modifying the service's desired count. If you want to delete a task definition
revision, you must first deregister the task definition revision.
You can't use an INACTIVE task definition to run new tasks or create new services,
and you can't update an existing service to reference an INACTIVE task definition.
However, there may be up to a 10-minute window following deregistration where these
restrictions have not yet taken effect.
At this time, INACTIVE task definitions remain discoverable in your account
indefinitely. However, this behavior is subject to change in the future. We don't
recommend that you rely on INACTIVE task definitions persisting beyond the
lifecycle of any associated tasks and services.
You must deregister a task definition revision before you delete it. For more information, see DeleteTaskDefinitions.
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 BeginDeregisterTaskDefinition and EndDeregisterTaskDefinition.
