Be sure that your project targets .net 4.5, that all references are valid and that web AspNet.WebPages.* are in the bin (Release/Debug) folder.
确保您的项目面向 .net 4.5，所有引用都有效，并且 web AspNet.WebPages.* 位于 bin (Release/Debug) 文件夹中。
You may also try to reinstall Microsoft.AspNet.WebPages nuget packages using this command in the package manager console
您也可以尝试在包管理器控制台中使用此命令重新安装 Microsoft.AspNet.WebPages nuget 包

I was encountering the exact error here (among a couple other missing reference errors) on my Win10 x64 system. My issue was (I believe), was caused by uninstalling something from add/remove that ripped out other dlls.
在我的 Win10 x64 系统上，我在这里遇到了确切的错误（以及其他几个缺失的参考错误）。我的问题是（我相信）是由于从删除其他 dll 的添加/删除中卸载某些内容引起的。

I had same issue where WCF was showing error of unrelated MVC assembly (I have multiple MVC projects in solution which are using System.Web.WebPages.Razor, Version=3.0.0.0). I installed Microsoft.AspNet.WebPages package in the WCF project , ran WCF proj and It worked. After that I had uninstalled all Microsoft.AspNet.WebPages related packages. It worked fine.
我有同样的问题，WCF 显示不相关的 MVC 程序集错误（我在解决方案中有多个 MVC 项目，它们使用 System.Web.WebPages.Razor，版本 = 3.0.0.0）。我在 WCF 项目中安装了 Microsoft.AspNet.WebPages 包，运行 WCF proj 并且它工作正常。之后我卸载了所有与 Microsoft.AspNet.WebPages 相关的软件包。它工作得很好。
