Database

public class Customer
{
    public int CustomerId { get; set; }
    public string Name { get; set; }
    public string Email { get; set; }
}

public class DiveShopContext:DbContext
{
  public DbSet<Customer> Customers { get; set; }
}

I want to be able to save Customers to my DB, i do it as follow:
<pre lang="cs">class Program
{
    static void Main(string[] args)
    {
       using (var db = new DiveShopContext())
       {

           var customer = new Customer();
           customer.CustomerId = 3045;
           customer.Name = &quot;Alex&quot;;

           db.Customers.Add(customer);
           db.SaveChanges();
       }
    }
}</pre>

Every thing is saved fine but the CustomerId is changed from 3045 to 1 and saved.
