There is a WCF (Windows Communication Foundation) service PassGuideService.
PassGuideService is self-hosted.
The implementations of contracts, the IGreetingService interface, the hosting code, and the
INameService interface are all being displayed in the exhibits.

At the moment the above code fails at line “return String.Format(“Hi there {0}, clientName);”.
You need to tweak the code in order to make it work.
What should you do? (select three)

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?

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?

DRAG DROP
There is WCF (Windows Communication Foundation) service which is being implemented.
The error information that is being sent to the user should not include stack trace information.

There is WCF (Windows Communication Foundation) service which is being implemented.

You use the class displayed in the exhibit.
The class must be exposed as a service named PassGuideA and operation OperationX.
The internal implementation at the service layer should not be exposed.
Which code should be used?

DRAG DROP
There is WCF (Windows Communication Foundation) service PassGuideService.
A data contract PassGuideContract for PassGuideService is being implemented.
PassGuideContract must be forward-compatible.
The round trips must include the information in PassGuideContract.
It should be able to add ew data members to PassGuideContract.
You do have to follow a strict schema validitiy.
Which interface should be used for PassGuideContract class?
