Siverlight I want to exit application or brower

Question

How to exit application or webrowser


Review Code below:


   private void Service_OpenCompleted(object sender, System.ComponentModel.AsyncCompletedEventArgs e)
    {
        if (e.Error != null)
        {
            ShowServiceWindow("EDAD SERVICE: Service Un-Available",e.Error.Message);

            // I want to close the application below. In windows forms. we normally do this.close or application.close

        }
    }
