PassGuideService Exhibit:
<ServiceContract>
Public Interface PassGuideService
<OperationContract>
Function GetPassGuideServiceTime() As DateTime
End Interface
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?

ServiceContract Exhibit:
<ServiceContract>
Public Class PassGuideService

Public Function PassGuideConfirm(ByVal PhoneNumber As String,ByVal wage As Double,ByVal
EmployeeNumber Integer) As Boolean ‘…

There is a WCF (Windows Communication Foundation) service PassGuideService.
PassGuideService exists within SOA (Service Oriented Architecture) within an enterprise.
The serviceContact of PassGuideService is displayed in the exhibit.
Method PassGuideConfirm, when executed, must be participate transperentally in existing
transactions.Furthermore, when there is no existing transaction, a new transaction must be
created.
How should the ServiceContract be tweaked to achieve is?

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.

DRAG DROP
There is a WCF (Windows Communication Foundation) service PassGuideService.
The clients and the service that uses PassGuideService use NetTcpBinding (transaction flow
enabled).
Assuming that the operations PassGuideOP1 and PassGuideOP2 are called within the same
client session, you need to enforce that they are executed within the same transaction context.
Which contract should PassGuideService have?

DRAG DROP
There is a WCF (Windows Communication Foundation) service application PassGuideApp.
PassGuideApp is required to provide service to a heavy client request load, even simulatanous
requests. Stateful conversation must be provided for each ensure subsequent individual client request.
