We want to develop addins for outlook, word and excel. As of now I am aware of 2 types of solutions. One to go for Shared Add-in (COM based) and other to build VSTO based Add-in.
As I am new to this, which would be the better option? (Or if there is 3rd way,please let me know) We are targeting Office 2003 and 2007 both. And I would prefer developing this addins in C#.
