In my project I have two png icons that I want to use as an icon depending on the same. I use this code to set the Icon but it throws this error:

string iconPath = isDarkMode
    ? "pack://application:,,,/dark.png"
    : "pack://application:,,,/light.png";

TrayIcon.IconSource = new BitmapImage(new(iconPath));

System.ArgumentException: Argument 'picture' must be a picture that can be used as a Icon.

As a workaround, I use the following code: TrayIcon.IconSource = new GeneratedIconSource {BackgroundSource = new BitmapImage(new (iconPath))};

I see that there is PngToIcoConverter class (but it is internal) that is used by the ImageExtensions.ToStream method but not by the async overload. Can you either make those classes public or should we use this workaround for setting png as an Icon?
