Remarks

The EntityPropertyMappingAttribute is applied to generated client data service classes when the metadata used to generate the classes indicates that custom feed mappings are defined in the data model. This information is necessary to make sure that the client can create and consume messages that support custom feeds. For more information, see Atom Feed Customization (WCF Data Services).
