推荐答案

你需要一些东西：

1）你必须使用.NET Framework 4.x.



2）添加对System.Web.WebPages.dll的引用。如果您已经在MVC项目中，这应该已经存在。



3）将Imports System.Web.Mvc添加到您尝试使用的文件的顶部如你所见，上课。

You need a few things:
1) You have to be using .NET Framework 4.x.

2) Add a reference to System.Web.WebPages.dll. If your already in a MVC project, this should already exist.

3) Add Imports System.Web.Mvc to the top of the file you are trying to use the class in, as you already are.
