Answer: A
QUESTION 2
You are creating a Windows Communication Foundation service by using Microsoft .NET Framework 3.5. The
service will be hosted in a managed Console application.
You want to add endpoints to the service. You need to ensure that all endpoints use the same base address.
Which code fragment should you use?
A. [ServiceContract]
public interface IMortgageService {}
public class MortgageService : IMortgageService {}
Uri baseAddress=new Uri("http://localhost:8888/MortgageService");
ServiceHost serviceHost= new ServiceHost(typeof(MortgageService), new Uri[] {baseAddress});
serviceHost.AddServiceEndpoint(typeof(IMortgageService), new BasicHttpBinding(),"");
serviceHost.Open();
B. [ServiceContract]
public interface IMortgageService {}
public class MortgageService : IMortgageService {}
Uri baseAddress=new Uri("http://localhost:8888/MortgageService");
ServiceHost serviceHost= new ServiceHost(typeof(MortgageService), new Uri[]{});
serviceHost.AddServiceEndpoint(typeof(IMortgageService), new BasicHttpBinding(), baseAddress);
serviceHost.Open();
C. [ServiceContract]
public interface IMortgageService {}
public class MortgageService : IMortgageService {}
string baseAddress="http://localhost:8888/MortgageService";
