ISystemMediaTransportControls::add_PropertyChanged method

[The feature associated with this page, Media Transport Controls, is a legacy feature. It has been superseded by System Media Transport Controls. System Media Transport Controls has been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use System Media Transport Controls instead of Media Transport Controls, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
