public void GetCustOrdersAsync() {

  DomainModelEntityManager mgr = = new DomainModelEntityManager();

  // Turn on async navigation.  This is a readonly property in Silverlight.
  mgr.UseAsyncNavigation = true;

  // Assume we already have a Customer instance. 
  // Navigate to customer orders.  
  // If UseAsyncNavigation is true and the orders aren't already in cache
  // the IsPendingEntityList flag will be on.

  var orders = _aCustomer.OrderSummaries;
  Assert.IsTrue(orders.IsPendingEntityList);

  // 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 
  // args.ResolvedEntities list.

  Assert.IsFalse(_customer.OrderSummaries.IsPendingEntityList);
  Assert.IsTrue(_customer.OrderSummaries.Count > 0);
}
