Hosting Code Exhibit:
ServiceHost host = new ServiceHost(typeof(CounterService));
NetTcpBinding bind1 =
new NetTcpBinding(SecurityMode None);
host.AddServiceEndpoint(”PassGuideApp.ICounterService”,
bind1, “net.tcp://localhost: 98765”);
host.Open0;
Bind2 exhibit:
host.AddServiceEndpoint(”PassGuideApp.ICounterService”,
bind2, “http:Illocalhost: 98765”);

There is a WCF (Windows Communication Foundation) self-hosted service PassGuideService.
PassGuideService provides a session-based counter.
PassGuideService is exposed over TCP.
The PassGuideService hosting code is being displayed in the exhibit.
PassGuideService must also be exposed over HTTP for external clients.
The session-counter must be able to perform over HTTP at it does over TCP.
How should bind2 be defined and configured?

Exhibit:
[ServiceContract]
[ServiceBehavior(ConcurrencyMode =
ConcurrencyMode.Multiple)]
public class DataAccessService
{
[OperationContract]
public void PutMessage(string message)
{
MessageDatabase.PutMessage(message);
}
[OperationContract]
public string SeachMessages(string search)
{
return MessageDatabase.SearchMessages(search);
}
}
There is a WCF (Windows Communication Foundation) service PassGuideService.
PassGuideService is specified in the exhibit.
PassGuideService is used over a TCP binding.
At the moment MessageDatabase only support a small finite number of concurrent executions of
the methods belonging to it.
While not preventing users to connecting to PassGuideService you need to tweak the
performance of PassGuideService so it allows the maximum number calls the methods.
What should be done?

DRAG DROP
Exhibit:
[ServiceContract]
public interface ITeamMessageService
{

[OperationContract]
string GetMessage0;
[OperationContract]
void PutMessage(string message);
}
There is a WCF (Windows Communication Foundation) service PassGuideService.
PassGuideService uses the contract being displayed in the exhibit.
PassGuideService is used to share messages between the clients.
You need to ensure that all the clients receive the same message from the GetMessage method,
even if the PutMessage method is used by another client.
Which code should be used?

There is a WCF (Windows Communication Foundation) service IPassGuideService in class
PassGuideService.
PassGuideService intermittently throws an exception and then fails.
Now you need to handle the unhandled exceptions to clients by sending the stack trace of these to
the clients as a fault message.
How can this be achieved?

Soap envelope exhibit:

<PassGuideStock xmlns=http://www.PassGuide.com”>
<ParticularID>1234 </ ParticularID >

The SOAP envelope in the exhibit must be generated.
How should this be achieved?

DRAG DROP
PassGuideService exhibit:
[OperationContract]
void PassGuideService(Order data);
There is a client PassGuideClient.
PassGuideClient sends multiple SOAP message to a WCF (Windows Communication Foundation)
service method PassGuideService.
PassGuideService must be tweaked so that any SOAP message can be received.
Which code should you use?

PassGuideService Exhibit:
[ServiceContract]
public interface PassGuideService
{
[OperationContract]
DateTime GetPassGuideServiceTime;
}
There is a class PassGuideService.
PassGuideService is hosted within an ASP.NET application PassGuideApp.
PassGuideService implements the interface being displayed in the exhibit.
PassGuideApp must be tweaked so that the GetPassGuideServiceTime method returns the result
formatted as JSON when request url ends in /PassGuide.
How can this be achieved?

Exhibit:
string void PassGuideDelete(string PassGuideId);
There is a WCF service PassGuideService.
PassGuideService implements restful manner operations.
The PassGuideDelete method is implemented as displayed in the exhibit.
When a client calls PassGuideService with the HTTP DELETE operation PassGuideService must
use this method.
How can this be achieved? Select two or three.

DRAG DROP
Exhibit:
[ServiceContract(CallbackContract = typeof(INameService))]
public interface IGreetingService
{
[OperationContract]
string PassGuideMessage();
}
[ServiceContract]
public intetface INameService
{
[OperationContract]
string PassGuideName();
}

There is a WCF (Windows Communication Foundation) solution PassGuideSol, which is using
some contracts being displayed in the exhibit.
Whenever the client uses PassGuideMessage on the service interface, the service uses the client
callback to call PassGuideName. Within the client the callback contract is implemented by the
NameService class.
The service callback must processed by an instance of NameService.
How should the client channed be implemented?

DRAG DROP
Exhibit:
[ServiceContract]
public interface IDataService
[OperationContract]
string PassGuideData();
There is a WCF (Windows Communication Foundation) solution PassGuideSol, which is exposing
the contract being displayed in the exhibit.
At the moment calls to PassGuideData has a 10 seconds completion time.
Current client calls makes blocking calls to PassGuideData.
New clients must be allowed to make non-blocking calls to obtain data from PassGuideData.
At the same time the existing clients must not break.
How can this be achieved?
