You are modifying a Windows Communication Foundation (WCF) service that issues
security tokens. The service is accessible through the named pipe protocol. No endpoints

are added in the service code. The configuration file for the service is as follows. (Line
numbers are included for reference only.) You need to ensure that new and existing client
applications can access the service through HTTP and named pipes. What should you do?

A.
Insert the following line at line 05. <endpoint address=”http://www.contoso.com”

B.
Insert the following line at line 08. <add baseAddress=”http://www.contoso.com” />

C.
Insert the following line at line 08. < add baseAddress=”net.tcp://www.contoso.com:8090″
