问题描述
我最近更新我的项目的MVC 5，6 EF。
我更新包通过控制台管理器（更新包）。
现在我看到吨警告有关在每个视图/局部视图/布局HTML佣工。
这些都是一些错误的：
- 'ViewBag'这个名字并不在目前的情况下存在
- 名称'风格'在目前情况下不存在
- 名称'脚本'在目前情况下不存在
- 'System.Web.WebPages.Html.HtmlHelper'不包含'偏'，没有扩展方法部分接受式的第一个参数定义System.Web.WebPages.Html.HtmlHelper'可以找到（是否缺少using指令或程序集引用？）
- 'System.Web.WebPages.Html.HtmlHelper'不包含定义'ActionLink的'...
- 'System.Web.WebPages.Html.HtmlHelper'不包含'BeginForm... 定义
- 'System.Web.WebPages.Html.HtmlHelper'不包含定义'AntiForgeryToken...
下面是视图/ webconfig：

装配版本需要匹配你已经升级到。另外，做了这些改变后，你可能需要做一个干净的/重建VS确保您清除旧的组件了。
i recently updated my project to mvc 5, EF 6. i updated all the packages via package console manager (update-package).
Now i see tons of warnings about the html helpers in every view/partial view/layout.
These are some of the errors:
- The name 'ViewBag' does not exist in the current context
- The name 'Styles' does not exist in the current context
- The name 'Scripts' does not exist in the current context
- 'System.Web.WebPages.Html.HtmlHelper' does not contain a definition for 'Partial' and no extension method 'Partial' accepting a first argument of type 'System.Web.WebPages.Html.HtmlHelper' could be found (are you missing a using directive or an assembly reference?)
- 'System.Web.WebPages.Html.HtmlHelper' does not contain a definition for 'ActionLink' ...
- 'System.Web.WebPages.Html.HtmlHelper' does not contain a definition for 'BeginForm' ...
- 'System.Web.WebPages.Html.HtmlHelper' does not contain a definition for 'AntiForgeryToken' ...

The assembly versions need to match what you have upgraded to. Also, after making these changes, you may need to do a clean/rebuild in VS to ensure you have cleared the old assemblies out.
