static void UpdateAppointment() {
DBAppointment[] insertedAppt = SchedulerExtension.GetAppointmentsToInsert<DBAppointment>(SchedulerSettingsHelper.CommonSchedulerSettings,
SchedulerDataHelper.FetchAppointmentsHelperMethod,
SchedulerDataHelper.GetResources());
foreach (var appt in insertedAppt) {
SchedulerDataHelper.InsertAppointment(appt);
}
DBAppointment[] updatedAppt = SchedulerExtension.GetAppointmentsToUpdate<DBAppointment>(SchedulerSettingsHelper.CommonSchedulerSettings,
SchedulerDataHelper.FetchAppointmentsHelperMethod,
SchedulerDataHelper.GetResources());
foreach (var appt in updatedAppt) {
