Extensibility Projects 

The Extensibility projects templates in the New Project dialog box enable you to create Add-ins, which are extensions of the Visual Studio integrated development environment (IDE).

Add-In Types

You can create two types of add-ins:

  • Visual Studio Add-ins — A Visual Studio add-in works only in the Visual Studio and Visual Studio Macros environments.

  • Shared Add-Ins — In addition to working in the Visual Studio and Visual Studio Macros environments, a shared Add-in also works in Microsoft Office applications, such as Microsoft Word, Microsoft Visio, and Microsoft Excel.

To open the New Project dialog box:

  1. On the File menu, point to New, and then click Project.

  2. Expand Other Project Types and click Extensibility.

    The Add-in project templates appear in the Templates pane.

Selecting either project starts the Add-In Wizard where you can select:

  • The programming language in which to create the Add-in.

  • The application hosts, such as Visual Studio or Microsoft Access.

  • Other Add-in options.

The Extensibility project templates create a project in the solution and a setup project for distributing the Add-in.
