Hey
At first set your id to assigned, use guid or something like that.
Second overload your Equals, gethashcode, (use id as equalifier) ,
also overload operators
Then create a static class countries
public static class Countries
{
public readonly static Country Australia = new Country
("EF989B65-1714-4e51-BAC2-D1766CA15A2C", "Australia");
// Optional
public static IEnumerable<Country> All
{
get
{
yield return Australia;
// ...
}
}
}
Kind Regards , remember assigned id's cannot be used with
saveorupdate, only save !!!
