A Windows Communication Foundation (WCF) service is self-hosted in a console application. The service implements the IDataAccess contract, which is defined in the MyApplication namespace. The service is implemented in a class named DataAccessService which implements the IDataAccess interface and also is defined in the MyApplication namespace. The hosting code is as follows. (Line numbers are included for reference only.) 01 static void Main(string[] args) 02 { 03 ServiceHost host; 04 ... 05 host.Open(); 06 Console.ReadLine(); 07 host.Close(); 08 } You need to create a ServiceHost instance and assign it to the host variable. You also need to instantiate the service host.Which line of code should you insert at line 04?（）
A. host = new ServiceHost("MyApplication.DataAccessService");
B. host = new ServiceHost("MyApplication.DataAccess");
C. host = new ServiceHost(typeof(IDataAccess));
D. host = new ServiceHost(typeof(DataAccessService)); -

A Windows Communication Foundation (WCF) service listens for messages at net.tcp://www.contoso.com/MyService.It has a logical address at http://www.contoso.com/MyService. The configuration for the WCF client is as follows:The generated configuration does not provide enough information for the client to communicate with the server.You need to update the client so that it can communicate with the server. What should you do?（）
A. In the client configuration, change the value of the address attribute to net.tcp://www.contoso.com/MyService
B. In the client configuration, change the value of the address attribute to net.tcp://www.contoso.com/MyService listen=http://www.contoso.com/MyService.
C. After instantiating the client and before invoking any service operation, add this line of code. EndpointBehaviors.Add(new EndpointDiscoveryBehavior(){ Enabled = true });
D. After instantiating the client and before invoking any service operation, add this line of code. client.Endpoint.Behaviors.Add(new ClientViaBehavior(new Uri("net.tcp://www.contoso.com/IMyService"))); -

You are modifying an existing Windows Communication Foundation (WCF) service that is defined as follows:[ServiceContract]public interface IMessageProcessor { [OperationContract] void ProcessMessages();}public class MessageProcessor: IMessageProcessor { public void ProcessMessage(); SubmitOrder();}SubmitOrder makes a call to another service. The ProcessMessage method does not perform as expected under a heavy load.You need to enable processing of multiple messages. New messages must only be processed when the ProcessMessage method is not processing requests,or when it is waiting for calls to SubmitOrder to return.Which attribute should you apply to the MessageProcessor class?（）
A. CallbackBehavior(ConcurrencyMode=ConcurencyMode.Reentrant)
B. CallbackBehavior(ConcurrencyMode=ConcurrencyMode.Multiple)
C. ServiceBehavior(ConcurrencyMode=ConcurrencyMode.Reentrant)
D. ServiceBehavior(ConcurrencyMode=ConcurrencyMode.Multiple)
