The NorthwindController.Customer partial class.

Partial Public Class NorthwindController
  Inherits LinqToEntitiesDataController(Of NorthwindEntities)

  Public Function GetCustomers() As IQueryable(Of Customer)
    Return ObjectContext.Customers.OrderBy(Function(c) c.CustomerID)
  End Function

  Public Sub InsertCustomer(entity As Customer)
    InsertEntity(entity)
  End Sub

  Public Sub UpdateCustomer(entity As Customer)
    UpdateEntity(entity)
  End Sub

  Public Sub DeleteCustomer(entity As Customer)
    DeleteEntity(entity)
  End Sub
End Class
