arduino.h: 48:17: fatal error: sam.h: No such file or directory

I am trying to compile a simple new project ('hello') for the Arduino M0 Pro. I have created a new project in visual studio 2015 (using vMicro).

But I get the error:

hello.ino: In file included from

arduino.h: 48:17: fatal error: sam.h: No such file or directory
   #include "sam.h"
   compilation terminated

Through the Arduino IDE - board manager I have installed the cores for Arduino SAM Boards and SAMD Boards. Currently it is on Arduino IDE: v1.6.18, SAM: v1.6.11 and SAMD: v1.6.15 (the newest version at time of writing).

The strange thing is that I do see that the project has included this file, as it is shown in the file tree of External Dependencies, see screenshot.

file tree showing sam.h

I have also checked the include paths in the 'hello.vcxproj' file. I have cut out the list below:

Even when I just open a completely new project in the Arduino IDE and try to compile it for Arduino M0, I get the exact same error!

I am stuck at this point. I've tried, as suggested at some other websites, de-installing SAM, de-installing SAMD, changing versions of either, but no luck.

reinstalling the Arduino IDE and packages/libraries solved the issue. – Arvest

In my case the specific solution was to delete the C:\Users[username]\AppData\Local\Arduino15 folder and reinstall the board packages I needed through the Arduino IDE Boards Manager.

Note this will not impact any libraries or other changes you have made in the IDE.
