I am not sure whether this applies to my problem, because it's not a WPF Client I am dealing with. Anyway it doesn't give us any hints on how to proceed in this case.
It applied. When you created the WCF service, you used a WPF DataWindow, because that's the version of the of DataWindow engine that the WPF service target uses.
Yakov Werde ran into this issue earlier and mentioned it to me. If he doesn't respond here, you might ping him to see what he might have done about it.
