System.InvalidOperationException: 'Property 'Expedit.Bokning' is not virtual. 'UseChangeTrackingProxies' requires all entity types to be public, unsealed, have virtual properties, and have a public or protected constructor. 'UseLazyLoadingProxies' requires only the navigation properties be virtual.'
I am using 'UseLazyLoadingProxies' and the navigation properties are set to virtual but it still does not work.

In C#/.Net is there a way to reflect from an object, which is a member of a collection up to the collection itself so we can (a) iterate over the other members of the collection, and (b) assuming the collection is itself a member of a collection follow the tree back up to the root?
A typical example would be if there is a common attribute which can be set at multiple levels the collection tree and when an object is changed, find the nearest trunk entry.
The only way to do it is if the type you are working with explicitly has things in it to handle this, in winforms this is handled via the IComponent.Site property. Other libraries may use other standards.

I am using a list in class Register:
Judging by the image your property O is a list of type List<Order> but the three items you are adding are of type Shop.
So either O needs to become a List<Shop> or the Order1, Order2, Order3 variables need to be type Order.
