我刚刚遇到了相同的问题，但是我最终实现的解决方案更像是一个hack：VS2015似乎将Windows SDK环境变量扩展为Windows 7 SDK，其中不包括fxc。

I just encountered the same issue, but the solution I finally implemented is more of a hack: It seems that VS2015 expands the Windows SDK environment variable to the Windows 7 SDK, which does not include fxc.

什么我最终所做的是添加 C：\Program Files（x86）\Windows Kits\10\bin\x86 和 C：＼在项目属性的 VC ++目录设置下，将程序文件（x86） Windows工具包 10 bin x64 到可执行目录变量。我不喜欢它，但是它可以工作...

What I eventually did is adding C:\Program Files (x86)\Windows Kits\10\bin\x86 and C:\Program Files (x86)\Windows Kits\10\bin\x64 to the "Executable Directories" variable under the "VC++ Directories" settings in the project properties. I do not like it, but it works ...
