我已通過更新剃刀從MVC4升級到MVC5次發行前的可怕的錯誤，在我引用的MVC網頁我有System.Web.Mvc，System.Web.Webpages，System.Web.Webpages.Razor和System.Web.Razor作爲版本v4.0.30319時，我跑我的應用程序得到升級到MVC5

[A]System.Web.WebPages.Razor.Configuration.HostSection cannot be cast to 
[B]System.Web.WebPages.Razor.Configuration.HostSection. 

Type A originates from 
'System.Web.WebPages.Razor, Version=2.0.0.0, Culture=neutral, 
PublicKeyToken=31bf3856ad364e35' in the context 'Default' at location 
'C:\Windows\Microsoft.Net\assembly\GAC_MSIL\System.Web.WebPages.Razor\v4.0_2.0.0.0__31bf3856ad364e35\System.Web.WebPages.Razor.dll'. 

Type B originates from 
'System.Web.WebPages.Razor, Version=3.0.0.0, Culture=neutral,

發現了什麼需在Views\Web.config完成。只要複製粘貼&超過你所擁有的這些部分：

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

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

<pages 
    validateRequest="false" 
    pageParserFilterType="System.Web.Mvc.ViewTypeParserFilter, System.Web.Mvc, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" 
    pageBaseType="System.Web.Mvc.ViewPage, System.Web.Mvc, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" 
    userControlBaseType="System.Web.Mvc.ViewUserControl, System.Web.Mvc, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35">

    </controls> 
</pages>

，就是這樣。任務完成！ ：d

不錯的一個BRO ...幫了我很多！ :)不得不改變它在3'Web.config'文件（在視圖文件夾內） - 主區和其他2區內。唷！他們可以使用'NuGet'包通過PowerShell腳本或其他東西自動更新它... –

剛剛更新了項目引用嗎？你還檢查了web.config嗎？還有那些引用的庫，並且通常具有庫本身的特定版本號。

在web.config中，你可以找到例如在引用的庫

：

<runtime> 
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1"> 
     <dependentAssembly> 
      <assemblyIdentity name="System.Web.Helpers" publicKeyToken="31bf3856ad364e35" /> 
      <bindingRedirect oldVersion="0.0.0.0-2.0.0.0" 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="0.0.0.0-2.0.0.0" newVersion="2.0.0.0" /> 
     </dependentAssembly> 
     <dependentAssembly> 
      <assemblyIdentity name="System.Web.WebPages.Razor" publicKeyToken="31bf3856ad364e35" culture="neutral" /> 
      <bindingRedirect oldVersion="0.0.0.0-2.0.0.0" newVersion="2.0.0.0" /> 
     </dependentAssembly> 
    </assemblyBinding> 
</runtime>

或

<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>

或

<system.web.webPages.razor> 
    <host factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc, Version=4.0.0.0, 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.Routing" />

</system.web.webPages.razor>

我幾乎要說確切的事情。我可以補充一點，你可以在你的web.config文件中加入一個版本重定向。另外，請記住您的Views文件夾也包含一個web.config文件。 –

@JuannStrauss：我使用了nuget，它可以幫助你 –

@JackM MVC5有哪些nuget包可用。你能提供你使用的特定nuget命令嗎？ –

這裏是從剃刀3視圖引擎新的ASP.NET MVC 5全Views\Web.config的。開箱即用（OOTB），原始的原始文件。

     </namespaces> 
    </pages> 
    </system.web.webPages.razor> 

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

    <system.webServer> 
    <handlers> 
     <remove name="BlockViewHandler"/> 
     <add name="BlockViewHandler" path="*" verb="*" preCondition="integratedMode" type="System.Web.HttpNotFoundHandler" /> 
    </handlers> 
    </system.webServer> 

    <system.web> 
    <compilation> 
     <assemblies> 
     <add assembly="System.Web.Mvc, Version=5.2.3.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> 
     </assemblies> 
    </compilation> 
    </system.web> 
</configuration>

這是一個很值得設置它和忘記它的文件，所以我希望這可以MVC4到MVC5升級幫助。確保然後檢查/交叉引用您的項目參考版本。我已經轉向使用NuGet進行包管理和管理依賴關係。
