Properties

	Name	Description
	KeepInContent	Gets a Boolean value that indicates whether a property value should be repeated both in the content section of the feed and in the mapped location.
	SourcePath	Gets the name of the property of the syndication item that will be mapped to the specified element of the feed.
	TargetNamespacePrefix	Gets a string value that, together with TargetNamespaceUri, specifies the namespace in which the TargetPathelement exists.

	GetType	Gets the Type of the current instance. (Inherited from Object.)
	Match	When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.)

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).
