将MVC4项目从VS2010升级到VS2012时出错 [英] Error while upgrading MVC4 project from VS2010 to VS2012

问题描述

我面临下面提到的错误。我已将MVC4项目从VS2010升级到VS2012。在本地它工作正常，但从服务器运行时产生问题。

Hi,
I am facing below mentioned error. I have upgraded MVC4 project from VS2010 to VS2012. On local it is working fine but creates issue while running from server.

Could not load file or assembly 'EntityFramework, Version=4.1.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040) 

推荐答案

看起来你正在使用的某些程序集仍尝试使用4.1而另一个EF5。确保你到处都引用相同的程序集。因此，你需要更新所有对使用EF5的引用并重建项目。 :)

It seems like some assemblies you are using still try to use 4.1 while the other EF5. Make sure you reference the same assembly everywhere. So, you need to update all the references to use EF5 and rebuild the project. :)
