如何从自托管wcf服务抛出FaultException？

static class Program
{
    [STAThread]
    static void Main()
    {
        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);
        Application.Run(new Form1());

        // Hook to this event below
        Application.ThreadException += new System.Threading.ThreadExceptionEventHandler(Application_ThreadException);
    }

    static void Application_ThreadException(object sender, System.Threading.ThreadExceptionEventArgs e)
    {
        if (e.Exception is FaultException)
            return; // Bypass FaultExceptions;
        else
            throw e.Exception; // Throw otherwise
    }
}
