Show running instance in single instance application

Question

I am building an application with C#.

I managed to turn this into a single instance application by checking if the same process is already running.

Process[] pname = Process.GetProcessesByName("SwapCardDesktop");
        if (pname.Length < 2)
        {
            // Launch Application
        }

I intend to have another functionality in here which brings up the running instance when tried to launch again.

I tried calling ShowWindowAsync() if application is already running,

ShowWindowAsync(hWnd, 9);

But this fails to bring up the application when minimized to tray.

Any suggestions on this?
