How to add an operation in callback?

[dantz]

HI Everyone,

I am very new in WCF. My current task now is to create additional functions in the callback contract so my Server side can execute it in the Client side.

My problem now is after I have added some new functions in my server callback, I am now updating the service refence in the client side. But then it just says

"Metadata contains a reference that cannot be resolved..."

But if I remove those functions that I just added in the callback contract, the client service reference can then easily update it.

Is there anything I am missing?

TIA

Sorry about this silly question.

It just needed to map all the functions in the service and client side. Must take note the use of IsOneWay = true for void functions.

Thanks
