Unloading add-ins with shared CommandBar menu

Hello Govert,

I'm creating multiple xll add-ins that display some of their commands exposed as `CommandBarControl` buttons in shared menus with `ExcelCommand` attribute.
Add-ins loading works as expected, however unloading "first" (first as in load order - the add-in responsible for initial command bar menu creation) add-in causes entire menu to disappear. Trying to unload any other add-in affected by this throws a `TargetInvocationException`.
This behavior is observed for any load/unload approach.

Is there a way to work around this without restarting the whole application? Are there any other ways to achieve something close to this modular UI?
