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.
