New Post: Performance issue

Hi,

Thanks for your prompt reply.

For functions in data layer, the function ToList() is called before return. For example,

public IEnumerable<Reminder> GetOverdueReminders(int vehicleId, DateTime forDate, int odometer)
        {
            return this.GetDbSet<Reminder>()
                    .Where( r => (r.VehicleId == vehicleId) && (r.DueDate < forDate || r.DueDistance < odometer) && !r.IsFulfilled)
                    .ToList();
        }

Executing ToList() would cause the query to execute immediately.

In VehicleController.JsonDetails, Take(3) would be carried out against the data in memory. i.e. more than enough data would be retrieved from DB

            var overdue = Using<GetOverdueRemindersForVehicle>()
                .Execute(id, DateTime.UtcNow, vehicle.Odometer ?? 0)
                .Take(3);

Thanks!
