How to retreive command line arguments

I’m working on an application right now where I’d like the user to be able to launch the application via a terminal, but also be able to specify a default file to load. e.g. myApp image.png I’m wondering if there is an easy way for my application to retrieve the command line argument that were passed into it at this part:

BuildAvaloniaApp().StartWithClassicDesktopLifetime(args);    // `args` comes from `Program.cs`'s `Main()`

E.g. In my App’s code, I’d like to be able to retreive those args and parse them to find an initial file:

        public override void OnFrameworkInitializationCompleted()
        {
            if (ApplicationLifetime is IClassicDesktopStyleApplicationLifetime desktop)
            {
                desktop.MainWindow = new MainWindow
                {
                    DataContext = new MainWindowViewModel(),
                };
                // Get those `args` somewhere around here and then pass them into a function in the `DataContext`

            }

            base.OnFrameworkInitializationCompleted();
        }

I saw that there was this entry on the wiki: https://github.com/AvaloniaUI/Avalonia/wiki/Application-lifetimes#manual-lifetime-management

AFAICT, it seems like the only way to pass those command line args off to my app’s code. Unless there is another way?

@Nikhilsp I put this in App.axaml.cs:

public override void OnFrameworkInitializationCompleted()
{
    var desktopLifetime = ApplicationLifetime as IClassicDesktopStyleApplicationLifetime;
    desktopLifetime!.Startup += (sender, args) =>
    {
        // Do stuff with args
        // Create your window
    };
}

@out4blood88 Your code works but the designer previewer of the .axaml files stops working. It just remains stuck on “The designer is loading”.
