Answer 1

Refer to complete code from here

You can pass arguments from your winform app like

Process.Start(new ProcessStartInfo(@"C:\\repos\\WpfApp.exe", "Args from WinForms"));

and receive in WPF app like

public partial class App : Application
    {
        protected override void OnStartup(StartupEventArgs e)
        {
            base.OnStartup(e);
            if (e.Args.Length > 0)
            {
                MessageBox.Show($"You have passed:{e.Args.Length} arguments," +
                    $" value are {string.Join( ",",e.Args)}");
            }
        }
    }

Answer 2

You can use the same method with a few parameters. So in your case

var procStart = System.Diagnostics.Process.Start(@"C:\ABC\WPF.exe", params);
