How to use AutoHotkey.dll in c#

[Parama]

I am trying to make my program with .NET C#. I wanna use feature of several commands of Autohotkey. So I was going to refer to Autohotkey.dll
but In my project(Visual Studio 2015), Autohotkey.dll is not refered to. In other words, it is not added to the reference list. Error Message box(can not add a reference. Make sure the file is accessible, and that the assembly or COM component is correct.) is poped up.
So I tried to use Autohotkey Interop that is found in this web site. but i don't know how to use this
I wanna use commands that is ControlClick, ControlSend. help me please
