我在您的全局web.config中立即看到兩個問題。

首先,這一行

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

需要更新到此行

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

第二,這些線

<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>

需要更新到這些行

<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>

程序集版本需要與升級後的版本相匹配。 此外,在進行這些更改後,您可能需要在VS中執行清理/重建以確保已清除舊的程序集。

我最近將我的項目更新為mvc 5,EF 6.我通過軟件包管理器管理器(update-package)更新了所有軟件包。

現在我在每個視圖/局部視圖/佈局中看到大量有關html助手的警告。

這些是一些錯誤:

  • “ViewBag”這個名稱在當前上下文中不存在
  • “Styles”這個名稱在當前上下文中不存在
  • “腳本”這個名稱在當前上下文中不存在
  • 'System.Web.WebPages.Html.HtmlHelper'不包含'Partial'的定義,也沒有擴展方法'Partial'接受類型'System.Web.WebPages.Html.HtmlHelper'的第一個參數可以找到(你是嗎?)缺少using指令或程序集引用?)
  • 'System.Web.WebPages.Html.HtmlHelper'不包含'ActionLink'的定義......
  • 'System.Web.WebPages.Html.HtmlHelper'不包含'BeginForm'的定義......
  • 'System.Web.WebPages.Html.HtmlHelper'不包含'AntiForgeryToken'的定義......

這是views / webconfig:
