Applied to business class properties. Indicates that a property or field references other aggregated persistent objects.
An aggregated object is a dependent object that is linked to its owner and cannot exist without its owner.
In XAF applications, apply DC.AggregatedAttribute only to business class properties of non-persistent objects or if you use Entity Framework. For more information on how to use the attribute, see One-to-Many (Aggregated).
In case of XPO, use the Xpo.AggregatedAttribute.
