DataAccessAdapterCoreUpdateEntitiesDirectlyAsync Method (IEntity2, IRelationPredicateBucket, CancellationToken)

Async variant of UpdateEntitiesDirectly(IEntity2, IRelationPredicateBucket). Updates all entities of the same type or subtype of the entity entityWithNewValues directly in the persistent storage if they match the filter supplied in filterBucket. Only the fields changed in entityWithNewValues are updated for these fields. Entities of a subtype of the type of entityWithNewValues which are affected by the filterBucket's filter will thus also be updated.
