I Found The Problem, vs 2012 doesn't support it(see update section of this answer)
我发现问题，vs 2012 不支持它（请参阅此答案的更新部分）
From Heresaid:
从这里说：
Unlike Razor V2 runtime and design time, VS2013 did not GAC these binaries. Instead, the binaries are installed in the project bin folder when corresponding NuGet package is installed, and in “%ProgramFiles (x86)%\Microsoft Visual Studio 12.0\Common7\IDE\CommonExtensions\Microsoft\Web\Razor\v3.0” to support design time.
与 Razor V2 运行时和设计时不同，VS2013 没有对这些二进制文件进行 GAC。而是在安装相应的 NuGet 包时将二进制文件安装在项目 bin 文件夹中，并在“%ProgramFiles (x86)%\Microsoft Visual Studio 12.0\Common7\IDE\CommonExtensions\Microsoft\Web\Razor\v3.0”中支持设计时间。
So we don't have these dlls in above path when upgrade to mvc5 /razor 3
因此，当升级到 mvc5 /razor 3 时，我们在上述路径中没有这些 dll
