// script "Tray icon region.cs"
using (var tir_ = new trayIconRegion()) {
    dialog.show("test", "with tray icon");
}
dialog.show("test", "without tray icon");


/// <summary>
/// Adds tray icon like <see cref="script.trayIcon"/>.
/// Removes it when disposing the variable.
/// </summary>
/// <remarks>
/// Use this in a script instead of <see cref="script.setup"/> if you want to remove the icon earlier than when the script process ends. If you need <c>script.setup</c> for other purposes, make sure its first argument is omitted or <c>false</c>.

}

In next LA will not need this class. Instead:

Code:

using (script.trayIcon()) {
    dialog.show("test", "with tray icon");
}
dialog.show("test", "without tray icon");
