Gets a value that specifies whether unknown data is ignored on deserialization and whether the IExtensibleDataObject interface is ignored on serialization.
Assembly: System.Runtime.Serialization (in System.Runtime.Serialization.dll)
The property affects types to which a DataContractAttribute attribute has been applied and that also implement the IExtensibleDataObject interface. In this case when IExtensibleDataObject is true, data added in future versions of the contract is ignored on read and write. For more information, see Forward-Compatible Data Contracts.
