I see below errors while compiling a project recently. This used to work absolutely fine few days back.
The include directories value in VC++ directories is $(VC_IncludePath)
$(WindowsSDK_IncludePath) which is evaluated to
C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\include
C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\atlmfc\include
C:\Program Files (x86)\Windows Kits\10\Include\10.0.10150.0\ucrt
C:\Program Files (x86)\Windows Kits\8.1\Include\um
C:\Program Files (x86)\Windows Kits\8.1\Include\shared
C:\Program Files (x86)\Windows Kits\8.1\Include\winrt
I see the missing header files in the above directories but the build is unable to find them
The build works fine if I add $(VC_IncludePath) $(WindowsSDK_IncludePath) to C/C++/general/additional Include directories.
Build is somehow not able to take include directories from the vc++ directories
Another observation is that intellisense is able to open these header files but the build is not able to.
How can I troubleshoot this further

Do you have the same problem with a newly created project?
@RLWA32 I do not see this issue with a newly created project.
What could be the issue with my already existing project ?

Hi @Srikar Veeramallu ,
Did you compare the .vcxproj files and can you build it correctly now?
If you try to remove(or rename) the hidden .vs folder in your solution folder, will these errors disappear?
@Srikar Veeramallu, Without seeing your actual project my best guess is that you have inadvertently changed an important project property. However, since a newly created project does not exhibit the same problems you can add your existing source code to a newly created project which should resolve your issue.
@RLWA32 Unfortunately I cannot give any other details of the project because it is products code. adding existing source to new product also does not work for me as I need to clone the project regularly.

Try comparing a project file (.vcxproj) that can build successfully with the problematic .vcxproj file. Since project files contain XML you should be able to use a file compare utility for this purpose. Perhaps you can see a difference that will identify the cause of your problem.
Another thing to try is to increase the logging created by MSBuild. It looks like you are using VS2015. In Tools->Options->Projects and Solutions->Build and Run increase the MSBuild log verbosity from the default value of Minimal to Detailed or Diagnostic. After a failed build you can review the log for errors.
