我在IIS 7(Windows Server 2008)上部署了WCF
服务,但我收到了一个奇怪的错误:
WebHost failed to process a request.

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].

同时我已经解决了这个问题。当我部署项目时 使用Web部署项目并设置'允许此预编译站点 可以更新'它工作正常。但我不知道为什么
