Did this work in a previous version of Visual Studio and/or previous .NET release?

No, it doesn't work on previous NetCore versions.

Issue description

In my NetCore project ,

1. I'm trying to use the CustomSelectedBarEditor class. In that class i've inherit this ObjectSelectorEditor.
2. In the Overridden FillTreeWithData function i've used the Selector as an argument and use the SelectorNode type of prop inside t my private FillTreeNodes function.

Issue:
I can be able to achieve this in my Framework project. but due to the unavailability of these three types I can't be able to achieve in NetCore projects.
