Remarks

This attribute provides an extender (an object that implements IExtenderProvider) with Visual Studio. To use ProvideExtenderAttribute, place it on a class that inherits from Package or implements IVsPackage.

This attribute class is used only to provide data for external registration tools. It does not have any effect on the runtime behavior of the VSPackage.

Note

C# automatically appends the word "Attribute" to the name of any attribute class. In C# code, refer to this attribute as ProvideExtender.

Note

The GUIDs for the Visual C# and Visual Basic project types are {FAE04EC0-301F-11D3-BF4B-00C04F79EFBC} and {F184B08F-C81C-45F6-A57F-5ABD9991F28F}, respectively.

When to Call
