Implements IPassGuideService. OperationOne
…
End Sub
Public Sub PassGuideTwo(ByVal value As String) —
Impements IPassGuideService. PassGuideTwo

Contract exhibit:
<ServiceContract(SessionMode s SessionMode.Required)>
Publc Interface IPassGuideService
<OperationContract(IsOneWay=True, IsInitiating=True)>
Sub PassGuideOne(ByVal value As String)
<OperationContract(IsOneWay=True, IsInitiating=False)>
Sub PassGuideTwo(ByVal value As String)
End Interface
