Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
|
|
GetHashCode | Returns the hash code for this instance. (Inherited from Attribute.) |

GetType | Gets the Type of the current instance. (Inherited from Object.) |

_Attribute.GetIDsOfNames | Maps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.) |
|
|
_Attribute.GetTypeInfo | Retrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.) |
|
|
_Attribute.GetTypeInfoCount | Retrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.) |

_Attribute.Invoke | Provides access to properties and methods exposed by an object. (Inherited from Attribute.) |
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>).
