Question

Hi sujeet Though List is known type WCF you don't need to declare it as service known type. So in that case [ServiceKnownType( typeOf ( someUserDefinedType))] is appropriate. Hope this will help you out. Feel free to write if more information is required. Don't forget to mark as answer if this helps.
