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\8.0\Extenders, during the installation of your add-in.
Dynamically, by calling this method in an add-in's OnConnection method.
NoteDynamically-registered Extender Providers must unregister themselves by calling UnregisterExtenderProvider during shutdown. Statically-registered providers should not do so.
- Full trust for the immediate caller. This member cannot be used by partially trusted code. For more information, see Using Libraries from Partially Trusted Code.
