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 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 service by using Microsoft .NET Framework 3.5. You write the following code fragment for the configuration setting. (Line numbers are included for reference only.)

01 <wsHttpBinding>
02 <binding name=”simple”>
04 </binding>
05 </wsHttpBinding>

You need to ensure that the service uses transport security and allows access to anonymous client applications. Which code fragment should you insert at line 03?

You create an application by using the Microsoft .NET Framework 3.5 and Microsoft
ADO.NET.The application contains a DataSet object that has a table. The DataSet object is
as shown in the following exhibit.
You need to ensure that the application meets the following requirements without creating another table:
The DataSet can be extended by using the designer.
The application displays all product records.
The product records can be filtered by ProductID.
