我也跟着该文章没有在启动时完全成功，但

I also follow that article without full success at start but

要解决这个简单创建新的Web MVC框架项目，并将其保存
然后打开web.config中，从意见，packages.config web.config文件，并在记事本中的.csproj

To fix this "simple" create new web mvc project and save it then open web.config, web.config from views, packages.config, and .csproj in notepad

然后打开您的项目，并期待在差异入境的文件版本号
例如在包中，你应该看到

then open your project and look at difference in entry for version numbers of files e.g. in packages you should see

<package id="Microsoft.AspNet.Mvc" version="5.0.0" targetFramework="net45" />

但你可以有

<package id="Microsoft.AspNet.Mvc" version="4.x.x.x" targetFramework="net40" />

在web.config中

in web.config

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

但你可以有

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

在.csproj的

<Reference Include="System.Web.Helpers, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL">
      <Private>True</Private>
      <HintPath>..\packages\Microsoft.AspNet.WebPages.3.0.0\lib\net45\System.Web.Helpers.dll</HintPath>
    </Reference>

但你可以有

<Reference Include="System.Web.Helpers, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL">
      <Private>True</Private>
      <HintPath>..\packages\Microsoft.AspNet.WebPages.2.0.20710.0\lib\net40\System.Web.Helpers.dll</HintPath>
    </Reference>

替换所有与新值

这是做按Ctrl + Shift + B后
在控制台的NuGet更新所有的包通过COMAND更新封装

after that do Ctrl+Shift+B and in nuget console update all packages by comand Update-Package

对于我这种工作终于
