Microsoft TS: Microsoft .NET Framework 3.5 C Windows Communication Foundation : 070-503

You are creating a client application that will call a Windows Communication Foundation service. The service was created by using Microsoft .NET Framework 3.5.
You write the following code segment.
[DataContract]
public class CreditCard {
private string cardNumber = 0; [DataMember] public string Name { get; set; } [DataMember] public string CardNumber { get { return cardNumber; } set { if (!IsValidCreditCardNumber(value)) { throw new ArgumentException("Invalid credit card number"); } cardNumber = value; } }
} You plan to share the validation logic between the client application and the WCF service.
You need to generate a client-side service proxy that includes the validation logic.
Which four tasks should you perform? (Each correct answer presents part of the solution. Choose four.)

• A. In the Client project, use the Add Reference dialog box to add a project reference to the Service project.
• B. In the Service project, add a reference to the Class Library project.
• C. In the Client project, add a reference to the Class Library project.
• D. Create a Class Library project for the DataContract classes.
• E. In the Client project, use the Add Service Reference dialog box to reference the service.
• F. In the Client project, use the Add Web Reference dialog box to reference the service.

You are creating a Windows Communication Foundation service by using Microsoft .NET Framework 3.5. The service will be hosted in a Console application.
You need to configure the service by using a configuration file other than the default app.config file. Which code segment should you use?

• A. Option D
• B. Option A
• C. Option C
• D. Option B

You are creating a Windows Communication Foundation service by using Microsoft .NET Framework 3.5. You create the following service contract.
[ServiceContract]
public interface IMyService
{
[OperationContract]
void DoSomething();
}
The service will not use any external resources.
You need to ensure that the calls to the DoSomething operation are thread-safe.
What are the two possible service implementations that you can use to achieve this goal?
(Each correct answer presents a complete solution. Choose two.)

• A. [ServiceBehavior(ConcurrencyMode=ConcurrencyMode.Multiple,
  InstanceContextMode=InstanceContextMode.PerSession)]
  public class serviceImpl : MyService
  {
  public void DoSomething(){ }
  }
• B. [ServiceBehavior(ConcurrencyMode=ConcurrencyMode.Single,
  InstanceContextMode=InstanceContextMode.Single)]
  public class serviceImpl : MyService
  {
  public void DoSomething(){ }
  }
• C. [ServiceBehavior(ConcurrencyMode=ConcurrencyMode.Multiple,
  InstanceContextMode=InstanceContextMode.PerCall)]
  public class serviceImpl : MyService
  {
  public void DoSomething(){ }
  }
• D. [ServiceBehavior(ConcurrencyMode=ConcurrencyMode.Multiple,
  InstanceContextMode=InstanceContextMode.Single)]
  public class serviceImpl : MyService
  {
  public void DoSomething(){ }
  }

You create a Windows Communication Foundation service by using Microsoft .NET Framework 3.5. The service contains the following code segment.

You need to create a service contract that meets the following requirements:
Which code segment should you use?

• A. Option D
• B. Option A
• C. Option C
• D. Option B

You are creating a Windows Communication Foundation (WCF) service by using Microsoft .NET Framework 3.5. You need to host the WCF service on the IIS Web server.
First, you create a new folder for your application files. Next, you use the IIS management tool to create a Web application in the new folder.
Which three actions should you perform next? (Each correct answer presents part of the solution. Choose three.)

• A. Create a service file that has the svc extension containing the @service directive information for the service. Move this file to the application folder.
• B. Create an App_Code sub-folder within the application folder for your code files. Place the code file that defines and implements the service contract in this folder.
• C. Create a web.config file that contains the appropriate configuration code. Place this file in the same folder as your service contract code.
• D. Create a vti_bin sub-folder within the application folder for your code files. Place the code file that defines and implements the service contract in this folder.
• E. Create a service file that has the .svc extension containing the @servicehost directive information for the service. Move this file to the application folder.
• F. Create a web.config file that contains the appropriate configuration code. Place this file in the application folder.
