Hi.
I've created a simple tray application. I tried to add icon to some menu item, but it fails.

  public class Desktoper
  {
    private readonly MenuItem[] _menuItems = new[]
    {
      new MenuItem
      {
        Label = "RunStop"
      },
      new MenuItem
      {
        Type = MenuType.separator
      }, 
      new MenuItem
      {
        Label = "Exit",
        Click = ()=> Electron.App.Exit(),
        Icon = "Desktop/icons/tray-stop-icon.png"  // <-- here fails
      }
    };


    public void Desktopize()
    {
      Electron.Tray.Show("Desktop/icons/tray-stop-icon.png", _menuItems);  // <-- here works fine
    }
  }

Here is the exception popup

May be it supports only some specific image formats? Help me pls to understand or figure it out.
Thanks!

This is a native electron problem. You need a complete path to the picture.

Solution for Electron.NET:

new MenuItem
{
    Label = "Exit",
    Click = ()=> Electron.App.Exit(),
    Icon = env.ContentRootPath + "/Desktop/icons/tray-stop-icon.png"
}
