This is my first foray into EF. The following code persists the customer, but the customer.ID field is not updated with the new PK value.

Is there something I've missed.

public Customer AddCustomer(Customer customer)
{
            using (var entities = new HillStationEntities())
            {
                entities.Customers.Add(customer);
                entities.SaveChanges();
                return customer;
            }
}

namespace HillStationPOS.Model.Entities
{
    using System;
    using System.Collections.Generic;
    
    public partial class Customer
    {
        public int Id { get; set; }
        public string Details { get; set; }
    }
}

Still the same, note Kendall Miller (new customer) has been added to the collection of customers in the after image:

Before:

After:

Yes, new records are added with an incrementing PK

All I did was change the structure of the table and it works now, Cheers.
