Shell_NotifyIcon: Acess denied and Capabilities generally

[avsteele]

I wanted to write an app which periodically reminded the user to do something and lived in the system tray otherwise.

However I see that Shell_NotifyIcon cannot be accessed in a partialTrust app. (#519)

The only related discussion is from 2021 but appears to indicate I need fullTrust to use this.

1. Is that still true?
2. The documentation for capabilities is not easy to browse. How can I figure out what Win32 calls are allowed with what permissions?
3. For an app like this which is long-running but tries to stay out of the way the system tray is ideal. If I cannot access it under partialTrust what are some recommended alternatives?

Thank you.
