我知道已经有一些在线解决方案,但是尝试所有解决方案后,我对自己感到困惑.
I understand there are some solutions online already but I am confused by myself after trying all the solutions.
我只想澄清我尝试过的解决方案:
I just want to clarify the solutions which I tried:
将名称空间添加到~/Views/Web.config(不是root Web.config).在我的~/Views/Web.config中,我有:
Add the namespace to ~/Views/Web.config(not root Web.config). In my ~/Views/Web.config I have: <system.web.webPages.razor> <host factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> <pages pageBaseType="System.Web.Mvc.WebViewPage"> <namespaces> <add namespace="System.Web.Helpers"/> <add namespace="System.Web.Mvc"/> <add namespace="System.Web.Mvc.Ajax"/> <add namespace="System.Web.Mvc.Html"/> <add namespace="System.Web.Optimization"/> <add namespace="System.Web.Routing"/> <add namespace="System.Web.WebPages"/> </namespaces> </pages> </system.web.webPages.razor>
并在我的根目录Web.config:
<system.web> <machineKey configSource="Config\MachineKey.config"/> <httpRuntime targetFramework="4.5" maxRequestLength="20480"/> <globalization culture="en-CA" uiCulture="en-CA"/> <customErrors mode="Off"/> <compilation debug="true" targetFramework="4.5"> <assemblies> <add assembly="System.Data.Entity, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"/> <add assembly="System.Web.Helpers, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/> </assemblies> </compilation> <pages buffer="true" enableViewState="false"> <namespaces> <add namespace="System.Web.Helpers"/> <add namespace="System.Web.Mvc"/> <add namespace="System.Web.Mvc.Ajax"/> <add namespace="System.Web.Mvc.Html"/> <add namespace="System.Web.Optimization"/> <add namespace="System.Web.Routing"/> <add namespace="System.Web.WebPages"/> </namespaces> </pages> </system.web>我在线搜索,其中一个答案告诉我名称空间应该相同.我做了,但是我没有任何改变.
I searched online and one of the answers told me the namespaces should be the same. I did but nothing changes to me.
确保目标版本.我的目标框架是4.5.我的MVC版本是5.2.0.0.其实我不明白这个解决方案.我试图将框架版本更改为4.5.1,而Visual Studio告诉我,我的版本实际上是4.5.我想我的目标版本还可以....(实际上我不理解此解决方案)
Make sure the target version. My target framework is 4.5. My MVC version is 5.2.0.0. Actually I am not understand this solution. I tried to change the framework version to 4.5.1 and the visual studio told me my version is actually 4.5. I guess my target version is OK....(Actually I do not understand this solution)
将@using System.Web.Optimization添加到~/Views/Shared/_Layout.cshtml.这使事情发生了.我的@Scripts.Render现在可以,但是@ViewBag下方仍然有一条红线.
Add @using System.Web.Optimization to ~/Views/Shared/_Layout.cshtml. This made something happens. My @Scripts.Render is OK now but @ViewBag still has a red line under it.
删除ComponentModelCache并重新启动Visual Studio.我正在使用VS2015.我尝试了,没有任何反应.
Delete ComponentModelCache and restart Visual Studio. I am using VS 2015. I tried, nothing happens.
稍后,我将更精确地执行这些解决方案,但我只想知道是否还有其他我错过并值得尝试的解决方案.非常感谢您的帮助!
I will perform these solutions more precisely later but I just want to know if there are other solutions I missed and worth trying. Thank you so much for the help !!
推荐答案经过几个小时的挖掘.我解决了我的问题.我的解决方案1 只能删除红线,当我运行Localhost调试时,它给了我500错误.
After a few hours digging. I solved my issue. My solution 1 can only remove the RED LINEs and it gave me 500 error When I run Localhost debug.
解决方案1:我只是在下面的~/Views/Web.config代码中将版本从3.0.0.0更改为2.0.0.0:
Solution 1: I simply changed the version from 3.0.0.0 to 2.0.0.0 in below code of ~/Views/Web.config:
<configSections> <sectionGroup name="system.web.webPages.razor" type="System.Web.WebPages.Razor.Configuration.RazorWebSectionGroup, System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"> <section name="host" type="System.Web.WebPages.Razor.Configuration.HostSection, System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" requirePermission="false" /> <section name="pages" type="System.Web.WebPages.Razor.Configuration.RazorPagesSection, System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" requirePermission="false" /> </sectionGroup>
当我将所有版本都更改为2.0.0.0时,红线消失了,但出现500错误.这表示system.web.webPages.razor已正确加载到_Layout.cshtml.
When I changed all the versions to 2.0.0.0, the red lines went away but I have 500 error. Which means system.web.webPages.razor loaded to the _Layout.cshtml correctly.
据我了解,如果system.web.webPages.razor版本不正确,则不会加载以下我的~/Views/Web.config设置:
To my understanding, My below settings of ~/Views/Web.config did not load if the system.web.webPages.razor version is incorrect:
<system.web.webPages.razor> <host factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc, Version=5.2.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> <pages pageBaseType="System.Web.Mvc.WebViewPage"> <namespaces> <add namespace="System.Web.Mvc" /> <add namespace="System.Web.Mvc.Ajax" /> <add namespace="System.Web.Mvc.Html" /> <add namespace="System.Web.Routing" /> <add namespace="System.Web.Optimization" /> </namespaces> </pages> </system.web.webPages.razor>解决方案2:然后,我检查了根Web.config中的以下部分代码:
Solution 2: Then, I checked below part of code in root Web.config:
<connectionStrings configSource="Config\ConnectionStrings-dev.config" /> <appSettings> <add key="webpages:Version" value="2.0.0.0" /> <add key="webpages:Enabled" value="false" /> <add key="PreserveLoginUrl" value="true" /> <add key="ClientValidationEnabled" value="true" /> <add key="UnobtrusiveJavaScriptEnabled" value="true" /> </appSettings>webpages:version是2.0.0.0.我将其更改为3.0.0.0以匹配~/Views/Web.config中的版本,重新启动Visual Studio,它可以正常工作.
the webpages:version is 2.0.0.0. I changed it to 3.0.0.0 to match the version in ~/Views/Web.config, restart visual studio, it worked without any issue.
