You are developing a Windows Communication Foundation (WCF) service. One of the
service operations contains the following code. You need to set a service behavior that
prevents two or more threads from incrementing the counter variable at the same time.
Which code segment should you use to set the service behavior?

Windows Communication Foundation (WCF) application uses a data contract that has
several data members. You need the application to throw a Serialization Exception if any of
the data members are not present when a serialized instance of the data contract is
deserialized. What should you do?

The following is an example of a SOAP envelope. <s:Enelope

that generates the SOAP envelope. 1 which code segment should you use?

You are developing a client that sends several types of SOP? messages to a Windows
Communication Foundation (WCF) service method named PostData PostData is currently
defined as follows: [OperationContract? void PostData(Order data); You need to modify
PostData so that it can receive any SO6P message which code segment should you use

A Windows Communication Foundation (WCF) service uses the following service contract.
[ServiceContract] public interface IService { [OperationContract] string Operation 1 (string
s); } You need to ensure that the operation contract Operationi responds to HTTP POST
requests. Which code segment should you use?

A Windows Communication Foundation (WCF) service uses the following service contract.
<ServiceContract> Public Interface IService <OperationContract0>? Function Operation 1
(RyVal s As String) As String End Interface You need to ensure that the operation contract
Operation 1 responds to HTTP POST requests. Which code segment should you use?

A Windows Communication Foundation (WCF) service implements a contract with one-way
and requestreply operations. The service is exposed over a TCP transport. Clients use a
router to communicate with the service. The router is implemented as follows. (Line
numbers are included for reference only.) 01 ServiceHost host = new
ServiceHost(typeof(RoutingService)); 02 host AddServiceEndpoint( 03
typeof(lSimplexDatagramRouter), 04 new NetTcpBinding0, “net.tcp:/flocalhostlRouter” 05);
06 List <ServiceEndpoints lep new List <ServiceEndpoint>0;t 07 lep.Add( 08 new
ServiceEndpoint( 09 ContractDescription.GetContract( 10 typeof(lSimplexDatagramRouter)
11), 12 new NetTcpBinding0, 13 new EndpointAddress|’nettcp://localhost: 8080/Logger”)
14) 15); 16 RoutingConfiguration rc new RoutingConfigurationO; 17 rC. FilterTable.Add(new
MatchAilMessageFilterO, lep); 18 host. Description. Behaviors. Add(new
RoutingBehavior(rc)); Request-reply operations are failing. You need to ensure that the
router can handle one-way and request-reply operations. What should you do?

A Windows Communication Foundation (WC9 service implements a contract with one-way
and requestreply operations. The service is exposed over a TCP transport Clients use a
router to communicate with the service. The router is impemented as follows. (Line numbers
are included for reference only.) 01 Dim host As ServiceHost = 02 New
ServiceHost(GetType(RoutingService)) 03 hostAddServiceEndpoint( 04

A Windows Communication Foundation (WCF) service listens for messages at net
tcpilwwwcontoso.comMMyService. It has a logical address at
http/Iwwwcontosocorn)MyService The configuration for the WCF client is as follows
<endpoint addressrhTttpllwwwcontosocom/MyService” bindinge”netTc pBinding”
bindingConfiguraton-NetTc pBinding_lMyService contract=”ServiceReference 1. IMyServce’
name=’NetTcpBinding_lllyService”/>v 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
