So I tried the atmel studio plugin without success ( http://www.visualmicro.com/forums/YaBB.pl?num=1515952156 ) now i'm trying Visual Studio before giving up on this extension. 

So I installed (in this order) :
* The C++ Mobile Development
* The  Arduino IDE for Visual Studio plugin
* Arduino GDB for Visual Studio 2017

(tried to uninstall/reinstall as well, tried to reboot my computer as well).

I can't find the "vMicro/Debugger/Microsoft GDB Debugger" option...

I also looked at the HKEY_CURRENT_USER\Software\Visual Micro\Options\Debug General\MicroGdb Location register key. It does exist, but the file didn't exist. I extracted files from the vsix and put it the same folder as the register key.

Is there a verbos log for your extension? Does it support non english os? custom Visual Studio directory? Space/special character in path, ...? What exacly is needed in the C++ Mobile Development? (Settings I need to make sure I have installed)

Tried on the VS2017 Community edition

Also once the extension is installed is there a fake programmer added in the list like with the Atmel Studio? (It was simulator programmer or something like that).

I want to debug it without hardware first (to double check code seem ok) then maybe debugging with hardware.
