推荐答案

请确保您的项目目标.NET 4.5，所有的引用是否有效以及网络AspNet.WebPages。*是在bin（发布/调试）文件夹

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.

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的NuGet包

You may also try to reinstall Microsoft.AspNet.WebPages nuget packages using this command in the package manager console

> Update-Package –reinstall Microsoft.AspNet.WebPages
