Hi all
I have a database with no constreains and no relations. This is just a converted flat-file database and must not be touched.

I nead to create entities with relations and tryed this:

[Table("Customers")]
public class customer
{
    [Key, Column("CustoemrID")]
    public int Id{get;set;}

    [Column("CustomerName")]
    public string Name{get;set;}

    [Column("Zip")]
    public int Zip{get;set;}

    [ForeignKey("Zip")]
    public ZipCode{get;set;}
}
[Table("ZipCodes")]
public class ZipCode
{
    [Key, Column("ZipCode")]
    public int ZipCode{get;set;}
    
    [Column("Name")]
    public string Name{get;set;}
}

I get errors on this and wander if there are some other ways to do this
