IEnumerable, IQueryable, or List? The technologies I'm considering using are Azure App Fabric Caching Entity Framework 4.1 Possibly Windows Server AppFabric 回答1: I would say build your DAL using IQueryable, and pass it around, make sure your object contects lifetime is the request.

Note : I can't bountify this question yet (it's too new), but I will reward a good answer with 50 points, and a great answer with 100 (when possible).

But nothing whatsoever about EF6. Let's say I have these entities: public DbSet<Person> Persons { get; set; } public DbSet<Order> Orders { get; set; } public DbSet<Invoice> Invoices { get; set; } Do I still need to create repositories for each entity? Or would a class suffice with some methods to do some custom
