asp.net-mvc – warns – html.helpers在项目更新后无法识别

分类：asp.Net作者：佚名
我最近更新了我的项目，mvc 5，EF 6。
我通过包控制台管理器(update-package)更新了所有的包。

现在我在每个视图/部分视图/布局中看到关于html助手的警告。

这些是一些错误：

>在当前上下文中不存在名称“ViewBag”
>当前上下文中不存在“样式”的名称
>在当前上下文中不存在“脚本”的名称
>’System.Web.WebPages.Html.HtmlHelper’不包含’Partial’的定义，并且没有扩展方法’Partial’接受类型’System.Web.WebPages.Html.HtmlHelper’的第一个参数可以被找到你缺少using指令或程序集引用？)
>’System.Web.WebPages.Html.HtmlHelper’不包含’ActionLink’的定义…
>’System.Web.WebPages.Html.HtmlHelper’不包含’BeginForm’的定义…
>’System.Web.WebPages.Html.HtmlHelper’不包含’AntiForgeryToken’的定义…

这里是views / webconfig：

解决方法

我的全球web.config中立即看到两个问题。

一，这一行

<add key="webpages:Version" value="2.0.0.0" />

需要更新到这一行

<add key="webpages:Version" value="3.0.0.0" />

二，这些线

<dependentAssembly>
  <assemblyIdentity name="System.Web.Helpers" publicKeyToken="31bf3856ad364e35" />
  <bindingRedirect oldVersion="1.0.0.0-2.0.0.0" newVersion="2.0.0.0" />
</dependentAssembly>
<dependentAssembly>
  <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" />
  <bindingRedirect oldVersion="1.0.0.0-4.0.0.0" newVersion="4.0.0.0" />
</dependentAssembly>
<dependentAssembly>
  <assemblyIdentity name="System.Web.WebPages" publicKeyToken="31bf3856ad364e35" />
  <bindingRedirect oldVersion="1.0.0.0-2.0.0.0" newVersion="2.0.0.0" />
</dependentAssembly>

需要更新到这些行

<dependentAssembly>
  <assemblyIdentity name="System.Web.Helpers" publicKeyToken="31bf3856ad364e35" />
  <bindingRedirect oldVersion="1.0.0.0-3.0.0.0" newVersion="3.0.0.0" />
</dependentAssembly>
<dependentAssembly>
  <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" />
  <bindingRedirect oldVersion="1.0.0.0-5.0.0.0" newVersion="5.0.0.0" />
</dependentAssembly>
<dependentAssembly>
  <assemblyIdentity name="System.Web.WebPages" publicKeyToken="31bf3856ad364e35" />
  <bindingRedirect oldVersion="1.0.0.0-3.0.0.0" newVersion="3.0.0.0" />
</dependentAssembly>

装配版本需要与您升级到的版本相匹配。此外，进行这些更改后，您可能需要在VS中进行干净/重建，以确保已清除旧的程序集。
