Question

I have an aggregate class that will contain a collection of another class, but that class will only ever exist in a collection on that aggregate, so I have no need for an ID on it in my code, or a need for a reference to the aggregate. For example:

public class SalesListing 
{
    public Guid Id { get; set; }
    public ICollection<LocalizedDescription> Descriptions { get; set; }
}

public class LocalizedDescription
{
    public string CultureCode { get; set; }
    public string Title { get; set; }
}

I’d like to just declare the key for the LocalizedDescription class as a combination of SalesListingId and CultureCode without creating a SalesListingId property or reference back to SalesListing. Any way to do this with EF 5.0 ?

For example, here’s an example how I’d imagine such an API would look like if it exists:

modelBuilder.Entity<LocalizedDescription>().BelongsTo<SalesListing>(s => s.Description)
            .WithKey((s, ld) => new { s.Id, ld.CultureCode })

No, you will still need to specify an ID
