You should only apply the DataServiceKeyAttribute attribute to a property that can be used to uniquely identify an instance of the entity type. This attribute is ignored when applied to a navigation property. For more information, see Reflection Provider (WCF Data Services).

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
