I've written a simple auto clicker using MouseKeyHook.
The reason I use MouseKeyHook is to detect global left clicks throughout Windows OS.
Although, when I run the .exe, the software lags on the click and after a while I can't seem to hit the 'X' button anymore and the application crashed my windows or slows down everything.
I am making this software to test our game, but this is not really helping :P
The code for the software can be found below:

}
}

SendInput(1, ref m_input, Marshal.SizeOf(m_input));
m_input.mi.dwFlags = MOUSEEVENTF_LEFTUP;
SendInput(1, ref m_input, Marshal.SizeOf(m_input));
}

{

Fixed the script by doing it another way. Turns out I had to attach it to a left mouse button down event :D
Here the script is:
