AddIn Interface

Defines the core functionality of add-ins that you create by using the Office development tools in Visual Studio.

Namespace: Microsoft.Office.Tools
Assembly: Microsoft.Office.Tools.Common (in Microsoft.Office.Tools.Common.dll)

Syntax

C++

[GuidAttribute("122bc42d-92fe-47f4-9f66-d7b282a1325b")]
public interface class AddIn : IBindableComponent, IComponent, 
	IDisposable

Properties

	Name	Description
	BindingContext	(Inherited from IBindableComponent.)
	DataBindings	(Inherited from IBindableComponent.)
	DataHost	This API supports the product infrastructure and is not intended to be used directly from your code.
	DefaultExtension	Gets the default extension for this AddIn object.
	Extension	Gets a custom extension for this AddIn object.
	HostContext	This API supports the product infrastructure and is not intended to be used directly from your code.
	ItemProvider	This API supports the product infrastructure and is not intended to be used directly from your code.
	Site	(Inherited from IComponent.)
	Tag	This API supports the product infrastructure and is not intended to be used directly from your code.

Methods

	Name	Description
	Dispose()	(Inherited from IDisposable.)

Events

	Name	Description
	BindingContextChanged	This API supports the product infrastructure and is not intended to be used directly from your code.
	Disposed	(Inherited from IComponent.)
	Shutdown	Occurs when the add-in is about to be unloaded.
	Startup	Occurs when the add-in is loaded, after all the initialization code in the assembly has run.

When you create an application-level add-in by using the Office development tools in Visual Studio, you typically do not use the AddIn interface directly. Instead, use the generated ThisAddIn class in your project. The ThisAddIn class derives most of its members from the AddInBase class. This base class redirects all calls to its members to an internal implementation of the AddIn interface in the Visual Studio Tools for Office runtime.

For more information, see Programming VSTO Add-Ins.

Note
This interface is implemented by the Visual Studio Tools for Office runtime. It is not intended to be implemented in your code. For more information, see Visual Studio Tools for Office Runtime Overview.

Usage

This documentation describes the version of this type that is used in Office projects that target the .NET Framework 4 or later. In projects that target the .NET Framework 3.5, this type might have different members and the code examples provided for this type might not work. For documentation about this type in projects that target the .NET Framework 3.5, see the following reference section in the Visual Studio 2008 documentation: http://go.microsoft.com/fwlink/?LinkId=160658.
