H.NotifyIcon: Creating a TaskbarIcon in-code causes windows to treat each instance as unique
Describe the bug
I may be doing something incorrectly, if so feel free to correct me.
I’m creating a new TaskbarIcon in-code by using
taskbarIcon = new TaskbarIcon();
taskbarIcon.Icon = new System.Drawing.Icon("Assets/(The icon)");
taskbarIcon.ToolTipText = "(tooltip name)";
But this creates a new “unique” icon every time, which floods settings and doesn’t let the user choose if the icon should be in the overflow menu or not.
Steps to reproduce the bug
- Create a
TaskbarIconmanually, using the code described above - Launch the app multiple times
- Check “Other system tray icons” in settings
Expected behavior
Only one entry for the application

Additional context
I may be doing something wrong, or creating a TaskbarIcon in-code may be fully unsupported.
It is quite possible there’s simply some ID property or something I’m not aware I need to set.

This may also be a Windows 11 bug which Microsoft needs to fix.
I recommend making another issue to track this if you would like; you may feel free to use my recording in it if you do so.
Yes of course. The main problem I want to solve is so that the user does not have to set a fixed GUID on a permanent basis (but with such an option if necessary). I need to check if
Assembly.GetEntryAssembly()returns the same Guid for the same application and different for different applications so that I can use this as the default behavior.
