Hi,
I'm trying to write an addin to restrict an specific type of file to be added only once in a project. And to restrict the deletion of it after one is added.
How can I do this?
The ProjectService.ProjectItemAdded and ProjectService.ProjectItemRemoved look like the right events to hook but they fire to late, I was looking something like ProjectItemAdding and ProjectItemRemoving but those does not exist.
Are there any other events that I can use?
thanks,
sean
