Hello,

When I use writeWml with an specific entity, i have an error :

                    Dim s As String = Nothing
                    Dim entity As New Entity()
                    entity.WriteXml(s)
            

ERROR MESSAGE --> "Object reference not set to an instance of an object."

Also, When i use WriteXml with an another entity, i don't have problem. It is only with my specific entity that i encountered an error

what's the runtime library version you're using? (rightmousebutton on ormsupportclasses dll -> properties -> version tab)
