My sketch (Dashboard) references a class (Commands) which includes a file (Robot.h) which is located in the same folder as Dashboard. The Commands class is in the libraries folder as a reusable class.

I have another sketch (CommandHandler) which also uses Commands and its own version of Robot.h which is located in the CommandHandler folder.

The purpose of this structure is to allow creation of multiple sketches that each consume a custom version of Robot.h.

CommandHandler finds its version of Robot.h, but Dashboard doesn't:

Dashboard.ino:41: In file included from
 
Commands.h: 13:19: fatal error: Robot.h: No such file or directory
   #include <Robot.h>
   compilation terminated
Debug build failed for project 'Dashboard'

I have seen a similar problem when I create a new class which often has problems finding "arduino.h" so there is something slightly wonky about the way that VM handles finding include files.

I have tried cleaning the solution (Build->Clean Solution), and deleting all files in the corresponding TEMP_BUILD_FOLDER, but haven't been able to spot a repeatable solution to these problems.

The compile output is attached.

The arduino forum is nothing to do with visual micro

Does it work in the arduino ide?
