Question

我正在尝试将64位版本的ELMAH 1.2包含在IIS Express本地托管的ASP.NET应用程序中。我引用了Elmah.dll的发布版本，以便它将复制到bin文件夹。对于本地工作站配置，我只想记录XML文件的异常。结果，我按如下方式配置了ELMAH：

<configuration>
    <sectionGroup name="elmah">
       <section name="errorLog" requirePermission="false" type="Elmah.ErrorLogSectionHandler, Elmah" />
    </sectionGroup>

    <elmah>
       <errorLog type="Elmah.XmlFileErrorLog, Elmah" logPath="C:\Logs\Elmah" />
    </elmah>

    <system.webServer>
       <handlers>
          <add name="Elmah" path="elmah.axd" verb="POST,GET,HEAD" type="Elmah.ErrorLogPageFactory, Elmah" preCondition="integratedMode" />
       </handlers>
       <modules>
          <add name="ErrorLog" type="Elmah.ErrorLogModule, Elmah" preCondition="managedHandler" />
       </modules>
    </system.webServer>
</configuration>

当我从Visual Studio启动调试会话时，该站点会加载并出现以下运行时错误：

无法加载文件或程序集“System.Data.SQLite”或其依赖项之一。尝试加载格式不正确的程序。

堆栈跟踪如下所示：

问题是，为什么ELMAH会导致运行时尝试加载System.Data.SQLite，因为我不想使用SQLite来记录异常？另外，我该如何解决这个问题（我已经在ELMAH谷歌群组和StackOverflow上找到了所有内容）？

这不是Elmah或SQLite的问题，问题是IISExpress在桌面上以32位运行。您需要为您的桌面运行32位，64位应该适合生产。

请查看：http://learn.iis.net/page.aspx/1010/iis-75-express-readme/，尤其是：

支持32位和64位系统，但只存在32位版本的IIS 7.5 Express。
