将我的MVC 3应用程序迁移到MVC 4

Question

我真的不知道该怎么做,我正在阅读这篇文章,该文章展示了如何手动迁移我的MVC 3应用程序.

我按照所有步骤操作,但在运行应用程序时出现以下错误:

'/'应用程序中的服务器错误.

无法加载文件或程序集'System.Web.WebPages.Razor,Version = 1.0.0.0,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.(HRESULT异常:0x80131040)

描述:执行当前Web请求期间发生未处理的异常.请查看堆栈跟踪以获取有关错误及其源自代码的位置的更多信息.

异常详细信息:System.IO.FileLoadException:无法加载文件或程序集'System.Web.WebPages.Razor,Version = 1.0.0.0,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.(HRESULT异常:0x80131040)

来源错误:

在执行当前Web请求期间生成了未处理的异常.可以使用下面的异常堆栈跟踪来识别有关异常的起源和位置的信息.

程序集加载跟踪:以下信息有助于确定无法加载程序集"System.Web.WebPages.Razor,Version = 1.0.0.0,Culture = neutral,PublicKeyToken = 31bf3856ad364e35"的原因.

警告:装配绑定日志记录已关闭.要启用程序集绑定失败日志记录,请将注册表值[HKLM\Software\Microsoft\Fusion!EnableLog](DWORD)设置为1.注意:程序集绑定失败日志记录会导致一些性能损失.要关闭此功能,请删除注册表值[HKLM\Software\Microsoft\Fusion!EnableLog].

我查看了代码,但是我没有看到只在1.0版本2.0中引用System.Web.WebPages.Razor.

使用NuGet并添加包Microsoft.AspNet.Mvc(Microsoft Asp.Net Mvc 4).这应该升级您的参考.看到:

https://nuget.org/packages/Microsoft.AspNet.Mvc

您需要升级web.config中的程序集引用.

从根web.config中删除:

<assemblies>
  <add assembly="System.Web.Helpers, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
  <add assembly="System.Web.Mvc, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
  <add assembly="System.Web.WebPages, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
</assemblies>

添加到根web.config:

<runtime>
  <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
    <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="0.0.0.0-4.0.0.0" 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>
  </assemblyBinding>
</runtime>

查看/ Web.Config中:

将Razor从1.0.0.0更改为2.0.0.0:

<configSections>
  <sectionGroup name="system.web.webPages.razor" type="System.Web.WebPages.Razor.Configuration.RazorWebSectionGroup, System.Web.WebPages.Razor, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35">
    <section name="host" type="System.Web.WebPages.Razor.Configuration.HostSection, System.Web.WebPages.Razor, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" />
    <section name="pages" type="System.Web.WebPages.Razor.Configuration.RazorPagesSection, System.Web.WebPages.Razor, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirePermission="false" />
  </sectionGroup>
</configSections>

<host factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />

<pages validateRequest="false"

       pageBaseType="System.Web.Mvc.ViewPage, System.Web.Mvc, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"
       userControlBaseType="System.Web.Mvc.ViewUserControl, System.Web.Mvc, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35">
