有时我在尝试通过crystal report和c＃生成报告时出错。但是这个错误并不是每次都发生，而是在某个时候发生。请告诉我为什么会出现这个错误以及如何解决它。

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].
