Question

我最近使用此网页上的说明更新到MVC 5：

http://www.asp.net/mvc/overview/releases/how-to-upgrade-an-aspnet-mvc-4-and-web-api-project-to-aspnet-mvc-5-and-web-api-2

我现在收到此错误：

无法加载文件或程序集'System.Web.Mvc，Version = 5.0.0.0，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）

奇怪的行为是，有时错误实际上是3.0.0.0版本，有时是5.0.0.0。

我已经做了很多搜索，但找不到任何有相同错误的人，只是类似的错误，人们讨论在配置文件中更改版本，所以这是我的配置条目：

在视图下：

  <system.web.webPages.razor>
    <host factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />

        Enabling request validation in view pages would cause validation to occur

        MVC performs request validation before a controller processes the input.

Answer 1

您说您已升级到版本5.2.2。因此你应该改变

<dependentAssembly>
    <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" />
    <bindingRedirect oldVersion="1.0.0.0-5.0.0.0" newVersion="5.0.0.0" />
</dependentAssembly>

到

<dependentAssembly>
    <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" />
    <bindingRedirect oldVersion="1.0.0.0-5.2.2.0" newVersion="5.2.2.0" />
</dependentAssembly>

显然，您需要将所有出现的MVC 5.0.0.0 替换为 5.2.2.0 。

Answer 2

我解决了我的问题，在中采用 PublicKeyToken 和版本 system.web-＆gt;编译 - ＆gt;程序集 Views \ web.config 并将其替换为同一文件，但在配置 - >运行时的 system.web.webPages.razor-＆gt;主机键和root web.cofig中 - ＆gt; assemblyBinding **并搜索名称为“System.Web.Mvc”的assemblyIdentity并替换其值。

Answer 3

您需要在项目中更新System.Mvc dll的版本。 SportStore.Domain和SportStore.UnitTests。

要先执行此操作，请转到其中一个项目并在项目名称中进行辅助点击 - ＆gt;选择＆＃34;管理NuGet包＆＃34;

之后

在内部管理NuGetPackages中，您可以访问＆＃34;更新＆＃34;选项卡并选择全部。在此内部，您将看到所有可用于更新的软件包。

选择MVC包上的Uptade。在我的照片中，由于我已经完全更新，我没有它。

将此操作重复到其他项目并重建您的项目。

Answer 4

主web.config中的所有assemblyBinding版本应该相同，并且每个Area查看web.config文件。我有同样的错误，请找到主web.config和区域视图之间的区别。

您可以在主web.config中找到System.Web.Mvc版本为4.0.0.0

<runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
            <dependentAssembly>
                <assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30AD4FE6B2A6AEED" culture="neutral"/>
                <bindingRedirect oldVersion="0.0.0.0-6.0.0.0" newVersion="6.0.0.0"/>
            </dependentAssembly>
            <dependentAssembly>
                <assemblyIdentity name="WebGrease" publicKeyToken="31BF3856AD364E35" culture="neutral"/>
                <bindingRedirect oldVersion="0.0.0.0-1.5.2.14234" newVersion="1.5.2.14234"/>
            </dependentAssembly>
      <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="1.0.0.0-4.0.0.0" 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>
      <dependentAssembly>
        <assemblyIdentity name="WebGrease" publicKeyToken="31bf3856ad364e35"/>
        <bindingRedirect oldVersion="0.0.0.0-1.3.0.0" newVersion="1.3.0.0"/>
      </dependentAssembly>
    </assemblyBinding>
  </runtime>

但是我在视图下的某个区域web.config是

<system.web.webPages.razor>
    <host factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc, Version=5.2.3.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
    <pages pageBaseType="System.Web.Mvc.WebViewPage">
     /pages>
  </system.web.webPages.razor>

请检查System.Web.Mvc，您获得的版本不同。所以主配置文件和区域视图配置文件应该更新版本相同。所以将主web.config文件更改为：

<runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
            <dependentAssembly>
                <assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30AD4FE6B2A6AEED" culture="neutral"/>
                <bindingRedirect oldVersion="0.0.0.0-6.0.0.0" newVersion="6.0.0.0"/>
            </dependentAssembly>
            <dependentAssembly>
                <assemblyIdentity name="WebGrease" publicKeyToken="31BF3856AD364E35" culture="neutral"/>
                <bindingRedirect oldVersion="0.0.0.0-1.5.2.14234" newVersion="1.5.2.14234"/>
            </dependentAssembly>
      <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="1.0.0.0-4.0.0.0" newVersion="5.2.3.0"/>
      </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>
      <dependentAssembly>
        <assemblyIdentity name="WebGrease" publicKeyToken="31bf3856ad364e35"/>
        <bindingRedirect oldVersion="0.0.0.0-1.3.0.0" newVersion="1.3.0.0"/>
      </dependentAssembly>
    </assemblyBinding>
  </runtime>

更新到版本5.2.2后，ASP.NET编译器无法加载System.Web.Mvc
