I am trying to include the 64-bit version of ELMAH 1.2 into an ASP.NET application that is hosted locally in IIS Express. I referenced the release version of Elmah.dll so that it would copy to the bin folder. For local workstation configuration purposes, I only want to log exceptions to XML files. As a result, I configured ELMAH as follows:

<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>

When I start a debugging session from Visual Studio, the site loads up and I get the following runtime error:

Could not load file or assembly 'System.Data.SQLite' or one of its dependencies. An attempt was made to load a program with an incorrect format.

The stack trace looks as follows:

[BadImageFormatException: Could not load file or assembly 'System.Data.SQLite' or one of its dependencies. An attempt was made to load a program with an incorrect format.]

The question is, why would ELMAH cause the runtime to try to load System.Data.SQLite since I do not want to use SQLite for logging the exception? Also, how can I resolve this issue (I looked everywhere on the ELMAH google group and on StackOverflow already)?

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

看看这个：http ://learn.iis.net/page.aspx/1010/iis-75-express-readme/ ，尤其是：

支持 32 位和 64 位系统，但仅存在 IIS 7.5 Express 的 32 位版本。
