I am currently working on a Visual Studio 2019 Extension and I am searching for a way to get notified when a project gets added or removed from the Solution Explorer. However I am trying to achieve this with native interfaces e.g. without the DTE.
I already tried using the IVsHierarchyEvents/IVsHierarchyEvents2, however it will only call the item added method, but not the item removed event. Is there any way you can achieve this?
