Hello,

After testing, this can be implemented in MAUI, you can refer to the steps below.

In WPF part:

Step 1.Add the Startup event to the App.xaml of your WPF program to receive parameters.

//in xaml
<Application 
    ...
    Startup="Application_Startup">

// in code-behind
private void Application_Startup(object sender, StartupEventArgs e)
{
    foreach (var item in e.Args)
    {
        //Operate on incoming parameters
    }
}

Step 2. Implement the ability to start WPF programs via ProcessStartInfo in MAUI.

private void StartWPFApp(object sender, EventArgs e)
{
    var path = "C:\\wpf1_test\\WpfApp1.exe"; //WPF program path
    if (File.Exists(path))
    {
        ProcessStartInfo startInfo = new ProcessStartInfo(path, "hello world")
        {
            CreateNoWindow = true,
            UseShellExecute = true,
        };
        Process.Start(startInfo);
    }
}
