There are three ways to solve this issue.

Ignore Precompiled Headers #1
Steps: Project > Properties > Configuration Properties > C/C++ > Command Line > in the Additional Options box add /Y-. (Screenshot of Property Pages) > Ok > Remove #include "stdafx.h"
Ignore Precompiled Headers #2
Steps: File > New > Project > ... > In the Application Wizard Window click Next > Uncheck the Precompiled Header box > Finish > Remove #include "stdafx.h"
Reinstall Visual Studio
This also worked for me, because I realized that maybe there was something wrong with my Windows SDK. I was using Windows 10, but with Windows SDK 8.1. You may have this problem as well.
Steps: Open Visual Studio Installer > Click on the three-lined Menu Bar > Uninstall > Restart your computer > Open Visual Studio Installer > Install what you want, but make sure you install only the latest Windows SDK 10, not multiple ones nor the 8.1.

The first time I installed Visual Studio, I would get an error stating that I needed to install Windows SDK 8.1. So I did, through Visual Studio Installer's Modify option. Perhaps this was a problem because I was installed it after Visual Studio was already installed, or because I needed SDK 10 instead. Just to be safe I did a complete reinstall.

I had the same problem building VS 2013 Project with Visual Studio 2017 IDE   The solution was to set the right   Platformtoolset  v120  Visual Studio 2013   Therefor there must be the Windows SDK 8 1 installed   If you want to use Platformtoolset v141  Visual Studio 2017   there must be Windows SDK 10   The Platformtoolset  can be chosen inside the properties dialog of the project   General -  Platformtoolset

Just in case you don t want to bump Windows SDK to Windows 10  you could be for example working on an open source project where the decision isn t yours to make   you can solve this problem in a Windows SDK 8 1 project by navigating Tools - gt  Get Tools and Features    - gt  Individual Compontents tab and installing the individual components  Windows 8 1 SDK   under SDKs  libraries and frameworks  and  Windows Universal CRT SDK   under Compilers  build tools and runtimes

Faced the problem of missing stdlib h and stdio h  and maybe more  after installing VS2017 Community on a new computer and migrating a solution from VS2013 to VS2017   Used  Maxim Akristiniy s proposal  but still got error message regarding toolset compatibility  However VS itself suggested to do solution retarget by right-clicking on the solution in Solution Explorer  then selecting Retarget solution from the menu and the updated Windows SDK Version from the drop-down list   Now my projects build w o a problem   Note that you may need to make the project your startup project for the retargeting to catch

Similar problem for me but a little different  I can compile and run the default CUDA 10 code with no problem  but there are a lots of error related to the stdio h file show in the edit window  Which is annoying  I solve it by change the code file name from  kernel cu  to  kernel cpp   That is wired but works for me  And it runs well so far

I had a similar problem after updating my VS2017  Project built fine  but lots of  errors  when code was brought up in the editor   Even tried reinstalling VS   I was able to solve it by setting the option    Ignore Standard Include Paths    to Yes   Attempted to build the solution with lots of errors   Went back and set the option to No   After rebuilding  my problem went away
