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，但仅当我加载 .cshtml 文件页面未加载时

“/blog”应用程序中的服务器错误。

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

说明：执行当前 Web 请求期间发生未处理的异常。请查看堆栈跟踪以获取有关错误及其源自代码的位置的更多信息。

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，因为这些将由 blogengine 继承应用程序，导致此异常，因为应用程序在其 bin 文件夹中找不到相关的 DLL。

我最近遇到了类似的问题，我已经在下面的虚拟目录中发布了我使用的 web.config。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，这是在 IIS7.5 中安装的 v6 Umbraco，因此您可能需要进行一些试验。

<?xml version="1.0"?>

<configuration>
  <configSections>
    <remove name="urlrewritingnet" />
    <remove name="umbraco.presentation.Properties.Settings" />
    <remove name="clientDependency" />
    <remove name="Examine" />

    <remove name="BaseRestExtensions" />
    <remove name="system.web.webPages.razor" />
  </configSections>

      <remove name="UmbracoModule" />
      <remove name="ClientDependencyModule" />

    </httpHandlers>    
    <compilation defaultLanguage="c#" debug="false" batch="false" targetFramework="4.0">
      <buildProviders>
        <remove extension=".cshtml" />
        <remove extension=".vbhtml" />
        <remove extension=".razor" />
      </buildProviders>
    </compilation>
    <membership>
      <providers>
        <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：

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

<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。
