Extending Office with Webpages

We have so far focused on writing extensions to the Office client applications through the traditional “add-in” notion: you use the usercontrol/Office project Item approach to design a user interface and code logic that is hosted within the target Office client app. In this last section, we cover a final project type—“App for Office”—that follows the same solution pattern but instead of using client technology allows you to write webpages that are then hosted within Office.
