Public Property IgnoreExtensionDataObject As Boolean
Property Value
true
if unknown serialization data is never sent; otherwise, false
. The default is false
.
Remarks
If a type implements the IExtensibleDataObject interface, it stores any extra data it does not know about that comes over the wire when deserializing into that type. For example, if a type Person
has members FirstName
and LastName
, and an element called PhoneNumber
comes in, it is stored. When later serializing the type, PhoneNumber
is re-emitted. The problem is that the schema for Person
exported by that service only has FirstName
and LastName
, so Windows Communication Foundation (WCF) generates a schema-invalid instance. If strict schema compliance is important, you can set IgnoreExtensionDataObject to true
to turn this re-emitting behavior off.
Regardless of the IgnoreExtensionDataObject setting, WCF always processes known data (both in and out) and does not throw exceptions when extra data comes in.
You can use the <callbackDebug> element to set this property in a client application configuration file.
