C#

By controlling serialization, it is possible to ensure serialization compatibility, which is the ability to serialize and deserialize between versions of a type without breaking the core functionality of the type.

public class FormSender
{
    FormListView formListView;

    // ...

    void MethodThatInstanciatesFormListView()
    {
        formListView = new FormListView();
        formListView.Show();
    }

    void ReadData()
    {
        List<Data> data = formListView.Read();
    }
    void AddData(Data data)
    {
        formListView.Add(data);
    }
}

public class FormListView
{
    public List<Data> Read()
    {
        // ...
    }
    public void Add(Data data)
    {
        // ...
    }
}
