For more information, see Features Available by Application and Project Type.

You can use add-ins to automate Microsoft Office applications, extend features of the application, and customize the user interface (UI) of the application. For information about how add-ins compare to other types of solutions you can create by using Visual Studio Tools for Office, see Office Solutions Development Overview.

Creating Add-in Projects

Create add-in projects by using one of the project templates in the New Project dialog box. These templates include required assembly references and project files. Visual Studio Tools for Office provides add-in project templates for most applications in Microsoft Office 2003 and the 2007 Microsoft Office system. For a complete list of the supported applications, see Features Available by Application and Project Type.

For more information about how to create an add-in project, see How to: Create Visual Studio Tools for Office Projects. For more information about the project templates, see Visual Studio Tools for Office Project Templates Overview.

Developing Add-in Projects

When you create an add-in project, Visual Studio Tools for Office automatically creates a ThisAddIn.vb (in Visual Basic) or ThisAddIn.cs (in C#) code file. This file contains the ThisAddIn class, which provides the foundation for your add-in. You can use members of this class to run code when the add-in is loaded or unloaded, to access the object model of the host application, and to extend features of the application. For more information, see Programming Application-Level Add-Ins.

Automating Applications by Using the Object Models

The object models of Microsoft Office applications expose many types that you can program against in an add-in. You can use these types to automate the application. For example, you can programmatically create and send an e-mail message in Outlook, or you can open a document and add content in Word. For more information about how to access the object model of the host application in code, see Programming Application-Level Add-Ins.

For more information about the object models of specific Microsoft Office applications, see the following topics:

Customizing the User Interface of Applications

There are several different ways to customize the UI of the host application by using an add-in:
