【问题描述】：

我已经在 IIS 7 (Windows Server 2008) 上部署了 WCF 服务，但是我收到了一个奇怪的错误：

WebHost failed to process a request.
 Sender Information: System.ServiceModel.Activation.HostedHttpRequestAsyncResult/31364015
 Exception: System.ServiceModel.ServiceActivationException: The service '/WCFService.svc' cannot be activated due to an exception during compilation.  The exception message is: Could not load file or assembly 'IHEC.WS.dll, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The parameter is incorrect. (Exception from HRESULT: 0x80070057 (E_INVALIDARG)). ---> System.Configuration.ConfigurationErrorsException: Could not load file or assembly 'IHEC.WS.dll, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies.

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].

奇怪的是，文件 IHEC.WS.dll 在 bin 目录中。

【问题讨论】：

您可以将其标记为“wtf”，以获得额外的强调。（开个玩笑）
对不起，我忘了。下次我会做的
同时我已经解决了这个问题。当我使用 Web 部署项目部署项目并设置“允许此预编译站点可更新”时，它工作正常。但我不知道为什么。
请发表此评论以回答您的问题。
我无法编辑帖子。我该怎么做？谢谢。
