Remarks
The class is treated as a media link entry, which is an AtomPub protocol for handling binary data and metadata about that binary data.
A type marked with this attribute has altered behavior when SaveChanges is called. The media property is also called 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>).
