The WCF service contains two operations named ProcessSimpleOrder and ProcessComplexOrder.
You need to expose the ProcessSimpleOrder operation to all the client applications. You also need to
expose the ProcessComplexOrder operation only to specific client applications.
Which code segment should you use?
A. <ServiceContract()> _
Public Interface IOrderManager
<OperationContract(Action:="*")> _
Sub ProcessSimpleOrder()
<OperationContract()> _
Sub ProcessComplexOrder()
End Interface
B. <ServiceContract()> _
Public Interface IOrderManager
<OperationContract(Name:="http: //contoso.com/Simple")> _
Sub ProcessSimpleOrder()
<OperationContract(Name:="http: //contoso.com/Complex")> _
Sub ProcessComplexOrder()
End Interface
C. <ServiceContract()> _
Public Interface ISimpleOrderManager
<OperationContract()> _
Sub ProcessSimpleOrder()
End Interface
<ServiceContract()> _
Public Interface IComplexOrderManager
Inherits ISimpleOrderManager
<OperationContract()> _
Sub ProcessComplexOrder()
End Interface
D. <ServiceContract()> _
Public Interface ISimpleOrderManager
<OperationContract(Name:="http: //contoso.com/Simple")> _
Sub ProcessSimpleOrder()
End Interface
Public Interface IComplexOrderManager
Inherits ISimpleOrderManager
<OperationContract(Name:="http: //contoso.com/Complex")> _
Sub ProcessComplexOrder()
End Interface
Correct Answer: C
