[AttributeUsageAttribute(AttributeTargets.Class, AllowMultiple = false, Inherited = true)]
public sealed class MediaEntryAttribute : Attribute

The MediaEntryAttribute type exposes the following members.

Public methodMediaEntryAttributeCreates a new instance of MediaEntryAttribute.

Public propertyMediaMemberNameThe name of the property on the class that holds the media, usually binary data.

Public methodEqualsInfrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeReturns the hash code for this instance. (Inherited from Attribute.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodMatchWhen overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

The class is treated as a media link entry, which is an AtomPub protocol for handling binary data and metadata about that binary data. The use of this attribute to define a media link entry is replaced by a new attribute that supports the streaming of binary media resource data. For more information, see WCF Data Services (Silverlight).

A type marked with this attribute has altered behavior when BeginSaveChanges is called. The media property is also known as a Media resource. On saving, the media property of the type denoted by the MediaMemberName property, is inserted by a POST request to the URI /<EntitySet>/$value.

After the POST, a PUT request with all the properties on the type other than the MediaMemberName property, which is binary content, are sent to the URI /<EntitySet>(<key>).
