Hello,

After testing, you could follow the steps below to open the Winforms program in MAUI.

For WinForms application, this example implements a WinForms program that accepts parameters and displays them in a label.

Step 1. Add parameters to the Forms main function:

static void Main(string[] args)
{
    // To customize application configuration such as set high DPI settings or default font,
    // see https://aka.ms/applicationconfiguration.
    string str = "";
    if (args.Length != 0)
    {
        foreach (string arg in args)
        {
            str += arg;
        }
    }
    ApplicationConfiguration.Initialize();
    Application.Run(new Form1(str));
}

Step 2. Implement a constructor for the Forms form that receives parameters.

public Form1(string str)
{
    InitializeComponent();
    label1.Text = str;
}

Step 3. Release the WinForms application.

For MAUI application:

Step 4. Pass the parameters via ProcessInfo and launch this WinForms application.

private void CounterBtn_Clicked(object sender, EventArgs e)
{
    var path = "C:\\wpf1_test\\WinFormsApp3.exe"; //WinForms program path
    if (File.Exists(path))
    {
        ProcessStartInfo startInfo = new ProcessStartInfo(path, "hello world")
        {
            CreateNoWindow = true,
            UseShellExecute = true,
        };
        Process.Start(startInfo);
    }
}
