[多选] You create a Visual Studio 2010 solution that includes a WCF service project and an ASP.NET project. The service includes a method named GetPeople that takes no arguments and returns an array of Person objects. The ASP.NET application uses a proxy class to access the service. You use the Add Service Reference wizard to generate the class. After you create the proxy, you move the service endpoint to a different port. You need to configure the client to use the new service address. In addition, you must change the implementation so that calls to the client proxy will return a List instead of an array. Which two actions should you perform?()
A . In the context menu for the service reference in the ASP.NET project, select the Configure Service Reference commSystem.Collections.Generic.List
B . In the context menu for the service reference in the ASP.NET project, select the Update Service Reference comma
C . Change the service interface and implementation to return a List
D . Edit the address property of the endpoint element in the web.config file to use the new service address
