How to automatically set the 'inserted Id' of the parent to the collection of referencing childs ?

[youssefbennour]

Hello,
I have a scenario similar to the below :

public class Parent {
        [PrimaryKey, AutoIncrement]
        public int Id { get; set; }
        [Reference]
        public HashSet<Child> Children { get; set; }
}
public class Child {
        [AutoIncrement, PrimaryKey]
        public int Id { get; set; }
        public int ParentId { get; set;}
        [Reference]
        public required Parent Parent { get; set; }
}

I want to insert an instance of the 'Parent' with it's 'Child' elements at once using Save(parentInstance, references: true)
but I get an error saying "Cant find 'ParentId' Property on Type Hashset.....
I thought that on Save(parentInstance, references: true) the 'ParentId' property in 'Child' elements will be set automatically, but as it appears to me that's not what's happening.
Am I missing somehting ?

Please read the docs for the feature you're using, if what you're trying to use doesn't exist in the docs (or anywhere else, e.g. Forums / StackOverflow / Source Code, etc) it's not supported.

Poco References need to use either Type for 1:1 relationships or List<Type> for 1:M relationships.
