#Include fails after May Upgrade - Workaround

I started using visual micro in Dec.  I have a few small projects.

This week I upgraded VM.  Now the INCLUDE directives in existing projects fail - even for header files in the same folder as the .ISO and .CPP files.

I found two workarounds.
1. (not preferred) Use absolute pathnames in the #include "..."  directives
2. (preferred) Created a new project.  Copy the source files.  #include <> and "" work as expected.

Hi,

It sounds like the header exists on disk but are not included in the project.

You can switch off this feature and force all files to be compiled but it is usually better that the source expected to be compiled is "Included" in the project tree. There are other beenfits to working this way but will leave for another time. 

The solution explorer/project tree has two views. 1) shows files on disk 2) shows files actually included in the project.

Can you please show a screen image of the solution tree when the project is open.

Thanks

The project is small enough I can attach it.  
In the .vcxproj file, you can see at line 82 the .h file is included.:
  <ItemGroup>
    <ClInclude Include="LED_Utils.h" />


I don't need you to fix this - I have created a new project.  I am raising the issue so you can understand what seems to be an unfortunate side effect of the upgrade.

Thanks for the zip

I changed:-
#include <LED_Utils.h>

to:-
#include "LED_Utils.h"

I test with the Arduino Ide and it also throws an error with <LED_Utils.h>. 

Visual micro was changed to work the same way as the arduino ide when previously the current project path was passed as a compiler -I include. It would be an option if people think it's a useful feature but normally anything outside of how arduino works can lead to other confusions.
