struct AppExtensionIdentity

A type that uniquely identifies an app extension on the system. Use this type to identify an app extension on the system and connect to it. You don’t create this type directly. Instead, you use the ``AppExtensionPoint/Monitor`` type to retrieve instances of this type for the available app extensions.
