Important: New name for apps for Office - Office Add-ins. We are currently updating our products, documentation, samples, and other resources to reflect the platform name change from "apps for Office and SharePoint" to "Office and SharePoint Add-ins".

While these changes are taking place, the dialogs and messages you see in your application might be different than what you see in this article.
