Question

我的WebRole无法启动但会不断重启并抛出此异常：

Application: WaIISHost.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception.
Exception Info: 
 System.IO.FileLoadException: Could not load file or assembly 'Autofac, Version=3.4.0.0, Culture=neutral, PublicKeyToken=17863af14b0044da' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

更新。在本文的帮助下添加了完整的错误说明： Troubleshooting Scenario 7 – Role Recycling

更新2.找到一篇关于异常的好文章。 Cloud Services roles recycling with the error “System.IO.FileLoadException: Could not load file or assembly”。这似乎足以解决问题。

它中断的原因是我的Azure实例，在E:\approot\bin\中没有MyDomain.Web.config个文件，其中包含Autofac所需的重定向。 web.config无法读取E:\approot\中的WaIISHost.exe。它就这样打破了。

Answer 1

它需要将mHandler.removeCallbacks(runnable);文件添加到解决方案（与web.config或app.config相同的级别）（将“复制到输出目录”属性设置为“始终复制”）。然后重新部署到Azure。此文件应包含<role name>.dll.config设置。

FileLoadException：无法在WebRole中加载文件或程序集（回收实例）
