How to Execute C# code in UiPath

@abdel, probably the first thing you’ll want to do is install AutoHotkey on your computer for experimenting.
You can download it from here.
I suggest also becoming familiar with AutoHotkey_H, which the provides the DLL that AutoHotkey.Interop wraps, which in UiPath can be accessed with the “Run Auto Hot Key script” activity.
To use C# in AutoHotkey, see this topic in the AHK forum.
Once you have been able to get your C# code to run, you can use “Run Auto Hot Key script” to execute your code.
I have also found LinqPad to be useful for testing code. It is much easier than firing up Visual Studio for the code I would typically run this way in UiPath.

I hope this will get you started.
