  D. Public Sub AfterCall( ByVal operationName As String, ByVal outputs() As Object, ByVal returnValue As Object, ByVal correlationState As Object) _ Implements IParameterInspector.AfterCall Return End Sub Public Function BeforeCall( ByVal operationName As String, ByVal inputs() As Object) As Object _ Implements IParameterInspector.BeforeCall Dim accountNumber As String = GetAccountNumber(inputs) Dim validator As AccountNumberValidator = New AccountNumberValidator() If (Not validator.Validate(accountNumber)) Then Return New FaultException() End If End Function
  C. Public Sub AfterCall( ByVal operationName As String, ByVal outputs() As Object, ByVal returnValue As Object, ByVal correlationState As Object) _ Implements IParameterInspector.AfterCall Dim accountNumber As String = GetAccountNumber(outputs) Dim validator As AccountNumberValidator = New AccountNumberValidator() If (Not validator.Validate(accountNumber)) Then returnValue = New FaultException() End If End Sub Public Function BeforeCall( ByVal operationName As String, ByVal inputs() As Object) As Object _ Implements IParameterInspector.BeforeCall Return Nothing End Function

• Question 277:

  A Windows Communication Foundation (WCF) service implements the following contract.

  [ServiceContract| public interface IHelloService { [OperationContract] [VVebGet(UriTemplate =

  "hello?namee{name}")] string SayHello(string name);

  }

  The implementation is as follows.

  public class HelloService: IHelloService { public string SayHello(string name)

  { return "Hello ".+ name;

  } }

  The senvice is self-hosted, and the hosting code is as follows.

  WebServiceHost svcHost = CreateHoseO;

  svcHost.OpenO;

  Console. ReadLineO;

  SrvHost.CloseO;

  You need to implement CreateHost so that the senvice has a single endpoint hosted at

  http://localhost:8000/HelloService which code segment should you use?

  A. WebServiceHost svcHost new WebServiceHost(typeof(HelloService)); svcHost.AddServiceEndpoint(typeof(lHelloService), new WebHttpBinding(WebHttpSecurityMode None), "http://localhost:8000/HelloService"); return svcHost;
  B. Ur baseAddress = new Urit'http:I/localhost:800O1");r WebServiceHost svc Host new WebServiceHost(typeof(HelloService), baseAddress); svcHostAddServiceEndpoint(typeof(lHelloService), new WebHttpBinding(WebHttpSecurityMode. None), "HelloService"); return svc Host;
  C. WebServiceHost svcHost = new Web Service Host(new HelloServiceO); svcHost AddServiceEndpoint(typeof(lHelloService), new WebHttpBinding(WebHttpSecurityMode. None), "http://Iocalhost: 8000/HelloService"); return svcHost
  D. Ur baseAddress new Uri('http //Iocalhost 8000/"); WebServiceHost svc Host = new WebServiceHost(new HelloService0, baseAddress), svc Host.AddServiceEndpoint(typeof(IHelloService), new WebHttpBinding(WebHttpSec urityMode None), "HelloService"); retumn svc Host;
  A. WebServiceHost svcHost new WebServiceHost(typeof(HelloService)); svcHost.AddServiceEndpoint(typeof(lHelloService), new WebHttpBinding(WebHttpSecurityMode None), "http://localhost:8000/HelloService"); return svcHost;

• Question 278:

  The service metadata is no longer available.

  You need to modify the previously generated proxy to include asynchronous calls to the service.

  What should you do?

  A. Update the service reference with the Generate asynchronous operations option.
  B. Create a partial class for the previously generated proxy and include the new asynchronous methods.
  C. Create a class with the same name as the previously generated proxy and add the new asynchronous methods. Add the new class to a namespace that is different from the original proxy.
  D. Create a class with the same name as the previously generated proxy and add the new asynchronous methods as partial methods. Add the new class to a namespace that is different from the original proxy.
  B. Create a partial class for the previously generated proxy and include the new asynchronous methods.

• Question 279:

  You are creating a client application and configuring it to call a Windows Communication Foundation (WCF) service. When the application is deployed, it will be configured to send all messages to a WCF routing service.

  You need to ensure that the application can consume the target service after the application is deployed.

  What should you do?

  A. In the client application, add a service reference to the router service. In the client binding configuration, specify the address of the router service.
  B. In the client application, add a service reference to the target service. In the client binding configuration, specify the address of the target service.
  C. In the client application, add a service reference to the router service. In the client binding configuration, specify the address of the target service.
  D. In the client application, add a service reference to the target service. In the client binding configuration, specify the address of the router service.
  D. In the client application, add a service reference to the target service. In the client binding configuration, specify the address of the router service.

• Question 280:

  You develop a Windows Communication Foundation (WCF) service to generate reports. Client applications call the service to initiate report generation but do not wait for the reports to be generated. The service does not provide any status to the client applications.

  The service class is defined as follows. (Line numbers are included for reference only.)

  01 02 Public Class ReportGeneratorService 03 04 Private Function GenerateReports(ByVal clientID As Integer) As Integer 05 and 06 Return 0 07 End Function 08 09 End Class

  Which two actions should you perform (Each correct answer presents part of the solution. Choose two.)

  A. Insert the following code at line 03.
  B. Insert the following code at line 03.
  C. At line 04, change the GenerateReports method from Private to Public.
  D. Remove line 06. At line 04, change the type of GenerateReports method to Sub. Remove the code As Integer from the method definition.
  A. Insert the following code at line 03.
  D. Remove line 06. At line 04, change the type of GenerateReports method to Sub. Remove the code As Integer from the method definition.
