c# – 无法加载文件或程序集“app_code”或其依赖项之一

2023年2月23日 303次阅读

这一直困扰我一段时间了：

Could not load file or assembly 'app_code' or one of its dependencies. 
The system cannot find the file specified.

我正在使用visual studio 2008和IIS6,由于某种原因,我得到了这个奇怪的错误.

为什么要加载’app_code’,为什么会失败？

试图解决它/使用异常中的信息找出更多

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].

但这没有帮助,msdn文章中关于程序集绑定日志查看器的信息也没有帮助：(http://msdn.microsoft.com/en-us/library/e74a18c4.aspx)

任何人都可以对这种可憎的事物发光吗？我猜这是一个新手的错误,但我不知道现在在哪里看.可能是IIS 6.0配置问题？我使用的是Windows XP Professional Edition和Visual Studio 2008.

在获得程序集绑定监视器后,它会喷出类似于：

最佳答案 如果使用Visual Studio Performance Tools,则Visual Studio可能会在web.config appsettings部分中保留一个键.它会导致加载32位库,如果您的应用程序以64位模式加载,则无法工作.

检查以下内容并将其删除：

<add key="Microsoft.VisualStudio.Enterprise.AspNetHelper.VsInstrLocation" value="C:\Program Files (x86)\Microsoft Visual Studio 11.0\Team Tools\Performance Tools\vsinstr.exe"/>
