Could you do it in VBA? Generally it's much simpler.

Hi,
I need to write an add-in for Excel 2007, but I'm a total noob to VSTO so
please forgive the dumb question. Unfortunately I can't find any demos
showing how to do what I want.
I started a new Excel 2007 add-in project and added a public function to
the
base class, so I would expect to be able to call that function from an
Excel
cell (e.g. =MyFunction(1,2,3) ).
Obviously this is an incorrect expectation because it doesn't appear in
the
function list, so what exacly am I doing wrong?

Really appreciate all your help.
