Is it possible to provide the sample of DataCotract class that you are using ?

No it is not working

DataContractSerializer is not intended for serializing delegates so if your DataContract class consists any delegate/event please exclude from serialization example [ field : NonSerialized ] public event SomeEventHandler SomeEvent ;
