As the title says.  This project builds OK on Arduino 1.8.   I do have 1.6/1.8 selected as "IDE" in
the visual micro  popup. 

  To set it up, I had to edit the .vcxproj file by hand - it was missing 16 .cpp files.

Concentrating on the very first error - I find no occurence of '__cplusplus' in the code.

The project name, folder name and an .ino name must all be the same for visual micro to manage an VS C++ project.

The output you see iif microsoft trying to compile a normal c++ project.

If you attempted to open an existing arduino project for the first time in VS then use "File>Open>Arduino Project" or open via the vMicro menu. Visual Micro automatically adds the code files you are expecting when you do this. It also creates a project with the correct name.

I guess the folder and an .ino have the same name otherwise arduino would not build.

If you are still unsure then zip the folder and email to us using the email address in the yellow box.

I recommend deleting the .vcxproj file that you have created and using the "file>open>arduino project" to open the standard arduino .ino. This will avoid any confusion.
