目前正在开发asp.net mvc5（旧的mvc3项目）。 它构建得很好，但是当我启动项目但是当我运行项目时，我面临以下错误。

Could not load file or assembly 'System.Web.Mvc' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

我不确定如何解决这个问题，任何想法？

这是程序集加载跟踪：

如果您仔细阅读了发布的融合日志，它会为您提供所需的信息。我将它剥离到重要的界限。

LOG: Attempting download of new URL file:///C:/Users/joaki/Source/Repos/2015-TimeAdministration/Source/V2/SalesWeb2/TimeReportV2/bin/System.Web.Mvc.DLL.

该应用正在寻找System.Web.Mvc.dll。它已将其解析为您的网络应用程序的bin文件夹下的文件夹： C：\ Users \ joaki \ Source \ Repos \ 2015-TimeAdministration \ Source \ V2 \ SalesWeb2 \ TimeReportV2 \ bin \ System .Web.Mvc.DLL

接下来，它检查web.config中是否存在该DLL的任何程序集绑定重定向，并找到一个：

LOG: Using application configuration file: C:\Users\joaki\Source\Repos\2015-TimeAdministration\Source\V2\SalesWeb2\TimeReportV2\web.config
LOG: Redirect found in application configuration file: 4.0.0.1 redirected to 5.2.3.0.
LOG: Post-policy reference: System.Web.Mvc, Version=5.2.3.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35

如果查看web.config，会出现类似这样的内容：

  <dependentAssembly>
    <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" />
    <bindingRedirect oldVersion="1.0.0.0-5.2.3.0" newVersion="5.2.3.0" />
  </dependentAssembly>

然后检查在应用程序的bin目录中找到的System.Web.Mvc.dll是否为同一版本：

WRN: Comparing the assembly name resulted in the mismatch: Major Version
ERR: Failed to complete setup of assembly (hr = 0x80131040). Probing terminated.

它抱怨主要版本不匹配。这是4号版本中的第一个号码。如果你回到日志中，那是因为bin文件夹中的System.Web.Mvc.dll实际上是版本 4 .0.0.1，而不是所需的 5 < /strong>.2.3.0：

LOG: Redirect found in application configuration file: 4.0.0.1 redirected to 5.2.3.0.

您需要检查您的解决方案，以确保所有引用System.Web.Mvc的项目都在寻找相同的最新版本。如果查看错误列表中的警告，您可能会发现有关此程序集的版本不匹配的警告。

更新参考文献

一种解决方案是右键单击Visual Studio中的解决方案，选择＆＃34;管理解决方案的NuGet包...＆＃34;并尝试更新项目以使用相同版本的System.Web.Mvc。

如果事先清除bin文件夹，它也会有所帮助。

您还可以使用程序包管理器控制台来更新解决方案中的程序包：

Update-Package Microsoft.AspNet.Mvc -version 5.2.3.0

答案 1 :(得分：2)

我不确定这是否会有所帮助。 但我也有这样的信息：

  

无法加载文件或程序集＆System; Web.Mvc（1）＆＃39;或其中一个   依赖...


我不知道为什么，但是当我查看Web应用程序的bin文件夹时，一些DLL文件有重复项，如＆＃34; System.Web.Mvc（1）.dll ＆＃34;等等。

我做的是，我删除了所有重复的文件（文件名用＆＃39;（1）＆＃39;或＆＃39;（2）＆＃39; ...就此而言，然后重建网络应用程序，然后它再次工作。

答案 2 :(得分：1)

你可以在这里发布你的web.config文件吗？您似乎在较新的环境中打开了一个mvc3项目，并且您的IDE（即Visual Studio）的迁移功能不能很好地工作。 System.Web.Mvc.DLL的版本不匹配（在配置文件和bin /目录中的版本）。有两种方法可以解决这个问题： 1.在配置文件中修改System.Web.Mvc包/程序集的版本。 2.将System.Web.Mvc.dll从旧项目复制到新项目（bin /文件夹）。

之前我遇到过其他.dll文件的类似问题。那时，我选择删除所有.dll文件，并使用NuGet Package Manager再次下载它们。
