    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.
