RuntimeClass Class

  • Article

Represents an instantiated class that inherits the specified number of interfaces, and provides the specified Windows Runtime, classic COM, and weak reference support.

You typically derive your WRL types from RuntimeClass because this class implements AddRef, Release, and QueryInterface, and helps manage the overall reference count of the module.
