It’s not as simple as I’d have liked, but there is a great class call ShellLink.cs at
vbAccelerator
This code uses interop, but does not rely on WSH.
Using this class, the code to create the shortcut is:
private static void configStep_addShortcutToStartupGroup()
{
using (ShellLink shortcut = new ShellLink())
{
shortcut.Target = Application.ExecutablePath;
shortcut.WorkingDirectory = Path.GetDirectoryName(Application.ExecutablePath);
shortcut.Description = "My Shorcut Name Here";
shortcut.DisplayMode = ShellLink.LinkDisplayMode.edmNormal;
shortcut.Save(STARTUP_SHORTCUT_FILEPATH);
}
}
