MessageBase and the [NonNonSerializeable] Possible?

Hey guys!

I’ve been trying to stop one of my Struct variables from getting Serialized so it could be only sent as null.

Using [System.NonSerialized] attribute on the variable dosnt seems to work, how could i stop the MessageBase serialization on that variable?

What do u guys think?
