asp.net-mvc – 无法加载文件或程序集’System.Web.WebPages.Razor’？

我有一个MVC5应用程序,我试图发布到Microsoft Azure Webhosting.当我在localhost上执行应用程序时,一切都按预期工作.但是,当我发布到Azure并尝试加载主机域时,我收到以下错误消息：

无法加载文件或程序集’System.Web.WebPages.Razor,Version = 2.0.0.0,Culture = neutral,PublicKeyToken = 31bf3856ad364e35’或其依赖项之一.定位的程序集的清单定义与程序集引用不匹配. (来自HRESULT的异常：0x80131040).

当我查看我的Web.Config文件时,我有以下内容：

< sectionGroup name =“system.web.webPages.razor”type =“System.Web.WebPages.Razor.Configuration.RazorWebSectionGroup,System.Web.WebPages.Razor,Version = 3.0.0.0,PublicKeyToken = 31BF3856AD364E35 “>
< section name =“host”type =“System.Web.WebPages.Razor.Configuration.HostSection,PublicKeyToken = 31BF3856AD364E35”requirePermission =“false” />
< section name =“pages”type =“System.Web.WebPages.Razor.Configuration.RazorPagesSection,PublicKeyToken = 31BF3856AD364E35”requirePermission =“false” />
< / sectionGroup>

如果我从错误消息收集的内容是正确的,我的应用程序或某个组件正在寻求版本2.0.0.0而不是3.0.0.0,但我不知道是什么/可能导致该问题.

发布到Azure时是否还有其他人遇到此问题？

编辑：

正如trailmax所建议的,我在Package Manager Console中执行了Add-BindingRedirect,结果如下：

PM> Add-BindingRedirect
Name                 OldVersion        NewVersion
--------------       ------------      -------------
System.Web.Mvc       0.0.0.0-5.1.0.0   5.1.0.0
System.Web.WebPages  0.0.0.0-3.0.0.0   3.0.0.0

然后我检查了localhost以验证所有内容仍处于正常工作状态(检查)并尝试再次发布到Azure.仍然是同一个问题：/

这是完整的细分：

EDIT2：

更正,主根Web.config文件已从Add-BindingRedirect修改.在发布时仍然收到同样的问题.

<runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <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="0.0.0.0-5.1.0.0" newVersion="5.1.0.0" />
      </dependentAssembly>
      <dependentAssembly>
        <assemblyIdentity name="System.Web.Optimization" publicKeyToken="31bf3856ad364e35" />

        <assemblyIdentity name="System.Web.WebPages" publicKeyToken="31bf3856ad364e35" />
        <bindingRedirect oldVersion="0.0.0.0-3.0.0.0" newVersion="3.0.0.0" />
      </dependentAssembly>
      <dependentAssembly>
        <assemblyIdentity name="WebGrease" publicKeyToken="31bf3856ad364e35" />
        <bindingRedirect oldVersion="0.0.0.0-1.5.2.14234" newVersion="1.5.2.14234" />
      </dependentAssembly>
    </assemblyBinding>
  </runtime>

解决方法

您可以使用命令在nuget console中执行此操作

PM> Add-BindingRedirect

如果该工具没有获取版本不匹配,您可以手动将其添加到web.config：

<configuration>
  <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="System.Web.WebPages.Razor" publicKeyToken="31bf3856ad364e35" culture="neutral"/>
        <bindingRedirect oldVersion="0.0.0.0-3.0.0.0" newVersion="3.0.0.0"/>
      </dependentAssembly>
    </assemblyBinding>
  </runtime>
</configuration>

找出哪个组件依赖于旧版本的方法之一,您可以使用依赖关系跟踪工具.我过去使用的那个叫做CheckAsm.免费版本足够一次或两次使用.
