You are implementing a WCF service library. You add a new code file that contains the following
code segment.

You build the service library and deploy its assembly to an IIS application. You need to ensure that
the GetCurrentRate method can be called from JavaScript. What should you do?

A.
Add a file named Service.svc to the IIS application.
Add the following code segment to the file.
<%@ ServiceHost Service=”ContosoWCF.IRateService”
Factory=”System.ServiceModel.Activation.WebScriptServiceHostFactory”
%>

B.
Add a file named Service.svc to the IIS application.
Add the following code segment to the file.
<%@ ServiceHost Service=”ContosoWCF.RateService”
Factory=”System.ServiceModel.Activation.WebScriptServiceHostFactory”
%>

C.
Apply the ScriptService attribute to the RateService class. Rebuild the WCF service library, and
redeploy the assembly to the IIS application.

D.
Apply the WebGet attribute to the GetCurrentRate interface method. Rebuild the WCF service
library, and redeploy the assembly to the IIS application.
