这个问题困扰了我一段时间:
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，但出于某种原因，我遇到了这个奇怪的错误。
为什么它会尝试加载“app_code”，为什么会失败？
尝试解决它/使用异常中的信息找出更多信息
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].
但这并没有帮助，msdn 文章中关于程序集绑定(bind)日志查看器的信息也没有帮助:( http://msdn.microsoft.com/en-us/library/e74a18c4.aspx )
任何人都可以照亮这个可憎的东西吗？我猜这是一个新手错误，但我现在不知道去哪里看。会不会是IIS 6.0配置问题？我使用的是 Windows XP 专业版和 Visual Studio 2008。
启动 Assembly 绑定(bind)监视器后，它会喷出如下内容:

最佳答案
如果您使用 Visual Studio Performance Tools，则 Visual Studio 可能会在您的 web.config appsettings 部分中留下一个键。它会导致加载 32 位库，如果您的应用程序以 64 位模式加载，这将不起作用。
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"/>
