how to make OrderBy() available to domain model

[Kit]

Dear all,

I am developing a model similar to the "Emloyee" and "Territories" in
the most update trunk.

I generated my models using ScaffoldingGeneratorCommand.tt.

However I find some difference between my model and northwind.

in EmployeesController.cs, Line 160


viewModel.AvailableTerritories =
territoriesRepository.GetAll().OrderBy(territory
=> territory.Description).ToList();

There is OrderBy() in the IList returned by
territoriesRepository.GetAll().

May I know how I can have the OrderBy() ? I believe I must have
missing some interface in my model or something else.

Thanks a lot for any help.
Regards,
Kit

The OrderBy method is a LINQ extension for collections.
