找不到 Razor 主机工厂类型：umbraco.MacroEngines.RazorUmbracoFactory、umbraco.MacroEngines

Question

我正在加载一个在 IIS7 和 IIS6 中使用 BlogEngine4 构建的博客，我已经完成了所有配置，并在 Google 的帮助下通过所有可能性缩小了问题范围。但我最终得到以下错误。谁有聪明的答案？

所有页面都加载正常，但只有当我加载 .cshtml 文件时页面没有加载

“/blog”应用程序中的服务器错误。

Could not locate Razor Host Factory type: umbraco.MacroEngines.RazorUmbracoFactory, umbraco.MacroEngines

如果您尝试在 Umbraco 站点的虚拟目录中托管 blogengine 站点，则必须修改 blogengine web.config 以“删除”所有 Umbraco 特定的处理程序和模块，因为这些将被继承由 blogengine 应用程序导致此异常，因为该应用程序在其 bin 文件夹中找不到相关的 DLL。

我最近遇到了类似的问题，我已经将我使用的 web.config 发布在下面的虚拟目录中。我的是一个非常简单的 Web 应用程序，所以显然这在您的 blogengine 应用程序中不会单独工作。您需要将相关部分添加到您的 web.config 文件中。

此外，这是针对 IIS7.5 中的 v6 Umbraco 安装，因此您可能需要进行一些试验。

<?xml version="1.0"?>

<configuration>
  <configSections>
    <remove name="urlrewritingnet" />

        <remove name="UmbracoMembershipProvider" />
        <remove name="UsersMembershipProvider" />
      </providers>
    </membership>
    <!-- added by NH to support membership providers in access layer -->
    <roleManager enabled="false">
      <providers>
        <remove name="UmbracoRoleProvider" />
      </providers>
    </roleManager>
    <!-- Sitemap provider-->
    <siteMap defaultProvider="UmbracoSiteMapProvider" enabled="false">
      <providers>
        <remove name="UmbracoSiteMapProvider" />
      </providers>
    </siteMap>

  </system.web>

  <system.webServer>
    <modules>
      <remove name="UrlRewriteModule" />
      <remove name="UmbracoModule" />
      <remove name="ClientDependencyModule" />
    </modules>
    <handlers accessPolicy="Read, Write, Script, Execute">
      <remove name="Channels" />
      <remove name="Channels_Word" />
      <remove name="ClientDependency" />
      <remove name="SpellChecker" />
    </handlers>
  </system.webServer>

</configuration>

更新：

如果您的应用程序 web.config 中存在 <system.web.webPages.razor> 部分，可能还需要更新该部分，将 host 和 pages 条目改回其默认值：

<host factoryType="System.Web.WebPages.Razor.WebRazorHostFactory,
    System.Web.WebPages.Razor" />
<pages pageBaseType="System.Web.WebPages.WebPage">

这是因为 Umbraco 实现了它自己的主机工厂和页面库。
