Getting ID of recently created entity - ADO Entity Framework

Question

Say you create an object and saving to database by using ADO Entity Framwork as in the code below.

private void CreateAddress(BizObjects.Address address)
{
    var entity = new EntityFramework.Address();

    entity.Line1 = address.Line1;
    entity.Line2 = address.Line2;
    entity.City = address.City;
    entity.State = address.State;
    entity.ZipCode = address.ZipCode;

    _entities.AddToAddress(entity);
    _entities.SaveChanges();
}

How can I retrieve the ID of the newly created object?

Thanks in advance.

Once you call "SaveChanges()" the entity object should have the ID field filled by the framework.

private void CreateAddress(BizObjects.Address address)
{
    var entity = new EntityFramework.Address();

    entity.Line1 = address.Line1;
    entity.Line2 = address.Line2;
    entity.City = address.City;
    entity.State = address.State;
    entity.ZipCode = address.ZipCode;

    _entities.AddToAddress(entity);
    _entities.SaveChanges();

    address.Id = entity.Id; // At this point the entity object will have the value of the Id field.
}

Hope this helps...
