在 Visual Studio 2012 中附加到某些进程时，我收到了这样的错误：
完整的异常如下所示：
System.BadImageFormatException: Could not load file or assembly 'C:\Program Files (x86)\SDK\Serv\bin\Debug\Service.dll' or one of its dependencies. An attempt was made to load a program with an incorrect format.
File name: 'file:///C:\Program Files (x86)\SDK\Serv\bin\Debug\Service.dll'

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].
这种问题的原因是什么以及如何避免它？
更新以提供更多详细信息
在程序集绑定日志查看器（Windows SDK 中的 FUSLOGVW.exe）中启用日志记录时，日志显示：
