C) (OperationContract(1sOneWay = true, Action "v', ReplyAction = ".') addPostData(BodyWriterdata);
D) [OperaionContract0sOneWay true, Action = 'v', ReplyAction void PostData(Order data);

2. You are developing a Windows Communication Foundation (WCF) service that contains the following service contract.
<ServiceContract() > Public Interface IPaymentService <OperationContract() > Sub RecordPayments(ByVal person As Person) End Interface Public Class Person End Class Public Class Employee Inherits Person End Class Public Class Customer Inherits Person End Class
You need to ensure that RecordPayments can correctly deserialize into an Employee or a Customer object.
What should you do?

A) Add the following KnownType attribute to the Employee class and to the Customer class. <KnownType(GetType(Person))>
B) Implement the IExtension(Of T) interface in the Person class.
C) Add the following KnownType attributes to the Person class. <KnownType(GetType(Employee))> <KnownType(GetType(Customer))>
D) Implement the IExtensibleDataObject interface in the Person class.

3. A class named TestService implements the following interface.
[ServiceContract]
public interface lTestService {
[OperationContract]
DateTime GetServiceTime;
}
TestService is hosted in an ASP.NET application.
You need to modify the application to allow the GetServiceTime method to return the data formatted as JSON.
It must do this only when the request URL ends in /ServiceTime.
What should you do?

A) Add this attribute to the GetServiceTime method
[WebGet(
ResponseFormat= WebMessageFormat.Json,
UriTemplatee="/ServiceTime")]
Create a new svc file named JsonVersion.svc with the following content.
<%@ ServiceHost Service"TestService'
Factorye="System.ServiceMode.ActivationWebServiceHostFactory" %>
B) Add this attribute to the GetServiceTime method.
[WebGet(UriTemplate = (Uson)/ServiceTime")]
Create a new .svc file named Jsonversion svc with the following content
<%@ ServiceHost Servicee"TestService"
Factory="System ServiceModel.ActivationWebServiceHostFactory" %>
C) Add this attribute to the GetServiceTime method.
[Weblnvoke(MetMode"POST")]
In the web.config file, add this element to
system.serviceModel/behaviors/endpointBehaviors.
<behavior namee"Json">
<enableWebScript />
</behavior>
In the web.config file, configure TestService in the system.serviceModel/services collection
as follows
<service namez"TestService">
<endpoint address"/ServiceTime"
contracts"TestService"
behaviorConfiguration="Json"
bindingz"webHttpBinding" />
</service>
D) Add this attribute to the GetServiceTime method.
[WebInvoke(Method = "GET',
UriTemplate "/ServiceTime",
ResponseFormat = WebMessageFormat.Json)]
In the web.config file, configure TestService in the system.serviceModel/services collection
as follows.
<service namez"TestService">
<endpoint address="/ServiceTime"
contract="TestService"
bindinge"webHttpBinding" />
</service>

4. You develop a Windows Communication Foundation (WCF) service. You enable all

B) ASP.NET State Service\State Server Sessions Total
C) ServiceModelService 4.0.0.0\Calls
D) ASP.NET State Service\State Server Sessions Active

5. You are developing a Windows Communication Foundation (WCF) service. The service needs to access out-of-process resources.
