  // Setup a handler to be called when data is returned.
 orders.PendingEntityListResolved += PendingOrdersResolvedHandler;
}

private void PendingOrdersResolvedHandler(object sender, PendingEntityListResolvedEventArgs<OrderSummary> args) {
  // The original RelatedEntityList will now contain the returned entities, as will the
