DataFilter
Filter Entity Framework IQueryable without extra code.
The demo states that it showcases using filter over an IQueryable , however in the code we can observe that an entire IQueryable is materialized in memory on initialization:
orders = dbContext.Orders.Include("OrderDetails.Product").Include("Customer").Include("Employee").ToList()
So eventually we observe filter operations over an in-memory IEnumerable, not over an IQueryable. At that a real IQueryable that showcases dynamic filtering over a child collection would have been very helpful.
