You create a Windows Communication Foundation service by using Microsoft .NET Framework 3.5. You write the following code segment for the service implementation. (Line numbers are included for reference only.)

01 public void PutMessage(Message msg)
02 {
03 string value=null;
05 }

You need to retrieve the content from the received message body and store it in the variable named value. Which code segment should you insert at line 04?

You are creating a Windows Communication Foundation service by using Microsoft .NET Framework 3.5.
You need to ensure that data sent in a SOAP header is in the following XML format.

<Data>
<string>String 1</string>
<string>String 2</string>
<string>String 3</string>
</Data>

Which code segment should you use?

You create a Windows Communication Foundation service by using Microsoft .NET Framework 3.5. You create the following service contract.

[ServiceContract]
public interface IMath
{
[OperationContract]
int Add(int num1, int num2);
}

You need to add an operation contract to perform the Add operation asynchronously. Which operation contract should you use?

You are creating a distributed client application by using Microsoft .NET Framework 3.5. You use Windows Communication Foundation (WCF) to create the application. You specify the following configuration settings for the service application.

<serviceCredentials>
<userNameAuthentication
userNamePasswordValidationMode=”MembershipProvider” membershipProviderName=”SqlMembershipProvider”/>
</serviceCredentials>

You need to authenticate the client application by using the Microsoft ASP.NET membership provider. Which configuration settings should you use?

You are creating a Windows Communication Foundation (WCF) service by using Microsoft .NET Framework 3.5. The WCF service will validate certificates to authorize client applications. You write the following code segment.

class Store: IStore
{
public void RemoveOrder(int ordered)
{}
}

You need to ensure that only those client applications that meet the following criteria can access the RemoveOrder method:

“AdminUser” is the subject in the client certificate. “1bf47e90f00acf4c0089cda65e0aadcf1cedd592” is the thumbprint in the client certificate.

You need to retrieve the content from the received message body and store it in the variable named value. Which code segment should you insert at line 04?

You are creating a Windows Communication Foundation service by using Microsoft .NET Framework 3.5. You write the following code segment. (Line numbers are included for reference only.)

01 [ServiceContract(Namespace=”http://uri.contoso.com”)] 02 public interface IMyService
03 {
04 [OperationContract]
05 string ProcessDetails(string s);

06 [OperationContract(Action=”UpdateStatus”)]
07 void UpdateStatus();
09 }

If the existing operation contract is unable to process a request made to the service, a generic operation contract must attempt to process the request. You need to create the generic operation contract. Which code segment should you insert at line 08?

You create an application by using Microsoft Visual Studio .NET 2008 and the .NET Framework 3.5. The application will be used by multiple types of users. The application will also interact with external applications. You need to design the interaction among the application, the users of the application, and the external applications. What should you do?

You create an application by using Microsoft Visual Studio .NET 2008 and the .NET Framework 3.5. The component will return custom business objects. You plan to develop a design strategy that meets the following requirements:

The component can be accessed by the .NET Windows applications and JavaScript-based Web applications. The component can be consumed by the client applications by using the minimum amount of code. The least amount of network bandwidth is consumed. You need to implement the design strategy by using the minimum amount of development effort. What should you do?

You create an application by using Microsoft Visual Studio .NET 2008 and the .NET Framework 3.5. The application stores human resources data in a Microsoft SQL Server 2008 database. A partial database schema is as shown in the exhibit. (Refer to the Exhibit.) Each time a row is added, modified, or deleted from the Employee table, a corresponding entry must be recorded in the EmployeeChangeLog table. You need to implement the data change logging.
