Assembly: System.Runtime.Serialization (in System.Runtime.Serialization.dll)
When implementing the IExtensibleDataObject, data from a future version of a type can be stored by the ExtensionDataObject. During a round trip (where an object is deserialized, altered, and serialized again), the extra data is stored and serialized again. For more information, see Serialization and Deserialization.
