Service Contract: Callback property

I have a couple of newbie questions:
1. The Create Service Contract wizard seems not to have the option for specifying the Callback property for the service contract for a Duplex connection, where can I set this particular property ( and other properties of the Service Contract).
2. Is it possible to specify a type 'out' parameter in a Service Operation.

  1. You should do that manually. WSSF V2 does not have that feature.
  2. Technically yes but WSSF does not allows you to do that since is not included in the guidelines that WSSF try to give (aka, not a recommended practice from a service oriented design standpoint).

Hi, charlyfriend, can you specify how to do that in FSME? I tried to add Callback attributes in ServiceContract partial class, but couldn't.
