ASP.NET 編譯器在更新到版本 5.2.2 後無法載入 System.Web.Mvc

我最近使用此網頁上的說明更新到 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

我現在收到此錯誤：

無法載入文件或程序集“System.Web.Mvc，Version=5.0.0.0，Culture=neutral，PublicKeyToken=31bf3856ad364e35”或其依賴項之一。找到的程序集的清單定義與程序集引用不匹配。（來自 HRESULT 的異常：0x80131040）

一個奇怪的行為是，有時錯誤實際上是版本 3.0.0.0，有時是 5.0.0.0。

我做了很多搜尋，但找不到任何有相同錯誤的人，只是人們在配置文件中討論更改版本的類似錯誤，所以這是我的配置條目：

在視圖下：

 <system.web.webPages.razor>
   <host factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
   <pages pageBaseType="System.Web.Mvc.WebViewPage">
     <namespaces>
       <add namespace="System.Web.Mvc" />
       <add namespace="System.Web.Mvc.Ajax" />
       <add namespace="System.Web.Mvc.Html" />
       <add namespace="System.Web.Optimization"/>
       <add namespace="System.Web.Routing" />
     </namespaces>
   </pages>
 </system.web.webPages.razor>

 <appSettings>
   <add key="webpages:Enabled" value="false" />
 </appSettings>


 <system.web>
   <httpHandlers>
     &lt;add path="*" verb="*" type="System.Web.HttpNotFoundHandler"/&gt;
   &lt;/httpHandlers&gt;

   &lt;!--
       Enabling request validation in view pages would cause validation to occur
       after the input has already been processed by the controller. By default
       MVC performs request validation before a controller processes the input.
       To change this behavior apply the ValidateInputAttribute to a
       controller or action.
   --&gt;
   &lt;pages
       validateRequest="false"
       pageParserFilterType="System.Web.Mvc.ViewTypeParserFilter, System.Web.Mvc, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"

   &lt;/pages&gt;

 &lt;/system.web&gt;

 &lt;system.webServer&gt;
   &lt;validation validateIntegratedModeConfiguration="false" /&gt;

   &lt;handlers&gt;
     &lt;remove name="BlockViewHandler"/&gt;
     &lt;add name="BlockViewHandler" path="*" verb="*" preCondition="integratedMode" type="System.Web.HttpNotFoundHandler" /&gt;
   &lt;/handlers&gt;
 &lt;/system.webServer&gt;
&lt;/configuration&gt;

還有我的網站 web.config 文件：

你說你已經升級到5.2.2版本。因此你應該改變

<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>

顯然，您需要將所有出現的 MVC 5.0.0.0替換為5.2.2.0。
