如何让VS2015 VC++的IntelliSense支持include用.h结尾的文件？

Question

如上图，不知道怎么了，MFC/ATL的头文件的include都报错，因为他们都是这样写的：

#include <string.h>

而改成这样：

#include <cstring>

就又好了

如下图：

Answer 1

Check if your vs2015 has the mfc development component installed. Mine is not installed. What is displayed in the mfc type project under visual eating++ is
instsll micrsoft foundation classes for c++
If it is the same for you, install it and see the effect.
For reference only!

Answer 2

If you are using the Community version, there is no MFC. If you are using Professional, MFC will not be selected by default unless you SelectAll or specifically click on it.
