pch issue E2998 warning and thousands of errors.

Question

I'm setting up a UWP DirectX app.

I'm getting the following error in my Application.cpp file on the #include "pch.h" line..

E2998 PCH warning: an unknown error occurred. An IntelliSense PCH file was not generated.

My pch.h file is as follows..

#pragma once

// Use the C++ standard templated min/max
#define NOMINMAX

#include "winrt/Windows.ApplicationModel.h"
#include "winrt/Windows.ApplicationModel.Core.h"
#include "winrt/Windows.ApplicationModel.Activation.h"

Answer 1

Someone suggested using the nuget version of C++/WinRT. That fixed at least this issue - though I can't understand why it wasn't using it already, because the project was a project template with the source taken out.
