I did a recording of the control then i open its filter properties and removed all information. then i open it search properties and try to add Taginstance in it search property and i got an Error "object reference not set to an instance on an object " and VS quits after this ?
- delete tag instance from filter properties
- save it
- add tag instance in search properties (it will throw exception and Exit VS that's fine
- re-open that file and go to search properties and Add Tag instance now it will add without exception
