Word Application-Level Add-in Development

An application-level add-in for Microsoft Office Word consists of an assembly that is loaded by Word. The assembly typically extends Word by customizing the user interface (UI) and by automating Word. Unlike a document-level customization, which is associated with a specific document, functionality that you implement in an add-in is not restricted to any single document.

For general information about application-level add-ins, see Getting Started Programming Application-Level Add-Ins and Architecture of Application-Level Add-Ins.

Word Add-in Programming Model

When you create a Word add-in project, Visual Studio Tools for Office generates a class, called ThisAddIn, which is the foundation of your solution. This class provides a starting point for writing your code, and it also exposes the object model of Word to your add-in.

For more information about the ThisAddIn class and other Visual Studio Tools for Office features you can use in an add-in, see Programming Application-Level Add-Ins.
