<AttributeUsageAttribute(AttributeTargets.Class, AllowMultiple := False,
	Inherited := True)>
Public NotInheritable Class MediaEntryAttribute
	Inherits Attribute
Name Description
System_CAPS_pubmethod MediaEntryAttribute(String)

Creates a new instance of MediaEntryAttribute.

Name Description
System_CAPS_pubproperty MediaMemberName

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

System_CAPS_pubproperty TypeId

When implemented in a derived class, gets a unique identifier for this Attribute.(Inherited from Attribute.)

Name Description
System_CAPS_pubmethod Equals(Object)

This API supports the product infrastructure and is not intended to be used directly from your code. Returns a value that indicates whether this instance is equal to a specified object.(Inherited from Attribute.)

System_CAPS_pubmethod GetHashCode()

Returns the hash code for this instance.(Inherited from Attribute.)

System_CAPS_pubmethod GetType()

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

System_CAPS_pubmethod IsDefaultAttribute()

When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.(Inherited from Attribute.)

System_CAPS_pubmethod Match(Object)

When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.(Inherited from Attribute.)

System_CAPS_pubmethod ToString()

Returns a string that represents the current object.(Inherited from Object.)

Name Description
System_CAPS_pubinterface System_CAPS_privmethod _Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr)

Maps a set of names to a corresponding set of dispatch identifiers.(Inherited from Attribute.)

System_CAPS_pubinterface System_CAPS_privmethod _Attribute.GetTypeInfo(UInt32, UInt32, IntPtr)

Retrieves the type information for an object, which can be used to get the type information for an interface.(Inherited from Attribute.)

System_CAPS_pubinterface System_CAPS_privmethod _Attribute.GetTypeInfoCount(UInt32)

Retrieves the number of type information interfaces that an object provides (either 0 or 1).(Inherited from Attribute.)

System_CAPS_pubinterface System_CAPS_privmethod _Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)

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>).
