                                            Question #1

                                            You create a client application by using Microsoft .NET Framework 3.5. The client application uses a Windows Communication Foundation (WCF) service.
                                            The WCF service analyzes incoming message headers to verify whether special processing of the message is required.
                                            The client application accompanies each call to the methods of the service with the address header. You write the following code segment. (Line numbers are included for reference only.)

                                            You need to ensure that the following requirements are met: Which code segment should you insert at line 08?

                                            You are creating a distributed application by using Microsoft .NET Framework 3.5. You use Windows Communication Foundation (WCF) to create the application.
                                            The distributed application contains client applications and a WCF service.
                                            The client applications send e-mail address claims to the WCF service. The custom authorization manager of the service examines whether the claims are of the type "http://contoso.com/ClaimTypes/UserStatus".
                                            You write the following code segment. (Line numbers are included for reference only.)

                                            You need to map the claim types that are provided by the client applications to the claim
                                            types that are expected by the custom authorization manager of the service. Which code segment should you insert at line 14?
