Microsoft Visual Studio PartnerIf you're developing Office add-ins, you're simply crazy to do so without Add-in Express

We've been using Add-in Express since 2004. It allows us to concentrate 100% on the features that set our products apart from the competition, rather than the very complicated plumbing that goes into the add-ins themselves. The product pays for itself during every coding session.
