The key entity is interesting, in this way i can use typed key and not a simply object, but c# does not support member aliasing so i cant find a simply way to achieve it
what I do not like very much is having to introduce this concept in my items, I do not know if it fits with the DDD logic

yes, it was only an example of some specific method, i edit the method name to explicit it

perhaps i have not explained well myself but i'm doing it as i wrote above and i come here to compare with community to see if there are better roads to do it.

I put the example just to explain better but we can very well be only on a theoretical:
-) there are best practices on how to map entities that refer each other?
-) lookup object that must be maintained can be modeled as Value Object?
