This seems to still be an issue with UE 5.1 - I’ve noticed this for some time but ignored as it wasn’t affecting my workflow but when I wanted to delete a C++ class recently read about the blueprint references on this blog from 2/13/23: Unreal Engine Integrations Now Available in Visual Studio 2022 - C++ Team Blog and was intrigued and then popped over here after saw it wasn’t working. I went to the marketplace and re-installed it for UE 5.1 with no luck.
