I believe that static is a requirement, but I'm not positive. Try it without
and see if it works. If it doesn't that still lets you set the externally
visible interfaces as static and still work with non-static methods and
properties.

Thanks, that is exactly what I have asked for.

One final question: As I can see, using this technique, only static
methods
and properties can be invoked on add-in class?
