You work as a Web Developer at Certkiller.com. You are in the process of creating a mobile Webapplication. You use Microsoft ASP.NET 3.5 to create the Web application. In an assembly named MobileUser the following code exists： namespace Certkiller.MobileUser { public class Capabilities { public static bool IsEnhancedDevice（MobileCapabilities capabilities， string optional） { return （capabilities["AJAX"] == Boolean.TrueString && capabilities["Silverlight"] == Boolean.TrueString）； } } } The following code is contained on a page in the Web application： MobileCapabilities capabilities = （MobileCapabilities）Request.Browser； bool isEnhancedDevice = capabilities.HasCapability（"SilverlightAndAjax"， null） You have to make sure that the code calls the IsEnhancedDevice method of the Capabilities class.You configure the Web.config file to accomplish this. What should you do？（）
