Remarks

RegisterExtenderProviderUnk is used by an IUnknown-based Extender Provider to dynamically register itself with the ObjectExtenders object under a particular CATID and name. An Extender Provider can register more than one Extender under one or more CATIDs.

There are two ways to register Extender Providers:

Statically, under the appropriate Extender CATID subkey in the registry key, HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\<version number>\Extenders, during the installation of your extension.
Note

Dynamically-registered Extender Providers must unregister themselves by calling UnregisterExtenderProvider during shutdown. Statically-registered providers should not do so.
