// Use the enumeration flags to indicate that this method exposes  
// shared state and self-affecting process management. 
// Either of the following attribute statements can be used to set the 
// resource flags.
[HostProtectionAttribute(SharedState = true, 
    SelfAffectingProcessMgmt = true)]
[HostProtectionAttribute(Resources = HostProtectionResource.SharedState |
private static void Exit(string Message, int Code)
    // Exit the sample when an exception is thrown.
    Console.WriteLine("\nFAILED: " + Message + " " + Code.ToString());
    Environment.ExitCode = Code;
