I unzip Traffic_Light.zip to the same directory level as a GDB/Zero Blink project which builds OK.

Upon opening Traffic_Light.sln pop-up is  "Team Foundation Server Version Control". I declined to contact the server. Next pop-up included "... binding information not found ..."

This is followed by "The active solution has been temporarily disconnected from source control because the server is unavailable.  To attempt to reconnect to source control, close and then re-open the solution when the server is available.  If you want to connect this solution to another server, use the Change Source Control dialog."

The build message is:
#include "lights.h"
                    ^
compilation terminated.

An error was encountered during the 'Deep Search' discovery process.
Either resolve the error or switch off the 'Deep Search Includes' option.
     Tip: When deep search is switched off, headers must be #included in the [project_name.ino] for all required libraries (for example: #include <SPI.h>)
     Tip: Deep search must be off if the project source contains links/shortcuts to code outside of the project structure. The source will have been #included using a relative path preceeded by ..\ (for example: #include "..\..\foo\foo.h")

Build with deep search turned off:

Compiling 'Traffic_Light' for 'Arduino/Genuino Zero (Programming Port)'
Traffic_Light.ino:28:20: fatal error: lights.h: No such file or directory
:#include "lights.h"
:compilation terminated
Error compiling project sources

If I close solution, attempt reopen by first signing in to Microsoft pop-up includes "res://ieframe.dll/http_404_webOC.htm"

What is the correct procedure to get this to build?

I am using:

Windows7
Arduino.c 1.6.9
VM 1606.17.10
Microsoft Visual Studio Community 2015 Version 14.0.25421.03 Update 3

Same error. Traffic_Light.txt attached, Deep Search off, Verbose on.

Added Lights.h & lamps.h and pressed F5. This appeared to build but could not copy output due to pop-up that "This project is out of date:" Traffic_Light - Debug Win32 "Would you like to build it? I clicked Yes, output:

If I click No to  pop-up that "This project is out of date:" Traffic_Light - Debug Win32 "Would you like to build it? The new pop-up is "Unable to start debugging. Cannot access as disposed object. Object name: 'Debugger'."

If I Build. Clean Build & Build.Rebuild Output.Micro Build is:

Pressing F5 generates "This project is out of date:" Traffic_Light - Debug Win32 "Would you like to build it? Yes, No or Cancel generates  pop-up is "Unable to start debugging. Cannot access as disposed object. Object name: 'Debugger'." which is as occurs in http://www.visualmicro.com/forums/YaBB.pl?num=1468416233

Thanks.

Clean and rebuild then F5 generates  pop-up is "Unable to start debugging. Cannot access as disposed object. Object name: 'Debugger'."
