Hi @Thanga Perumal Ramasamy (SX/ETM12-EM) ，

You can use the ShowWindowAsync function and the SetForegroundWindow function to activate and bring your app window to the foreground.

    [DllImport("user32.dll")]
    private static extern bool ShowWindowAsync(IntPtr hWnd, int nCmdShow);

    [DllImport("user32.dll")]
    private static extern bool SetForegroundWindow(IntPtr hWnd);

    static void Main(string[] args)
    {
        string processName = "YourApplicationName";

        Process[] processes = Process.GetProcessesByName(processName);

        if (processes.Length > 0)
        {
            IntPtr mainWindowHandle = processes[0].MainWindowHandle;

            ShowWindowAsync(mainWindowHandle, 3);

            SetForegroundWindow(mainWindowHandle);
        }
        else
        {
            Console.WriteLine("Application not found.");
        }
    }
}

Best Regards.
