EF查询报错 Unable to load one or more of the requested types.

在本机调试发布能正常运行
在服务器（IIS6）上则报错

问题已解决 抓取System.Reflection.ReflectionTypeLoadException异常 记录异常里LoaderExceptions 属性，发现错误信息是mvc 4.0.0.1无法加载程序集 既然知道错误了就好解决了 在服务器上目录创建以下路径文件即可 C:\WINDOWS\Microsoft.Net\assembly\GAC_MSIL\System.Web.Mvc\v4.0_4.0.0.1__31bf3856ad364e35\System.Web.Mvc.dll
