[09:47:59 WRN] The same entity is being tracked as different entity types 'Item.Price#Price' and 'OrderPosition.Price#Price' with defining navigations. If a property value changes, it will result in two store changes, which might not be the desired outcome.

Instances of owned entity types cannot be shared by multiple owners (this is a well-known scenario for value objects that cannot be implemented using owned entity types).
