c# - 无法加载文件或程序集 'EntityFramework' 或其依赖项之一。程序集可能已被篡改

Question

我正在尝试通过 Visual Studio 2012 将我的 Webforms 项目发布到我的主机 1&1。我的网络项目在本地零问题上运行良好。它成功构建和发布，但是，在输入域 url 时出现以下错误。

Could not load file or assembly 'EntityFramework' or one of its dependencies. Strong name signature could not be verified.  The assembly may have been tampered with, or it was delay signed but not fully signed with the correct private key. (Exception from HRESULT: 0x80131045)



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].

您的主机 1&1 似乎没有安装 .Net 4.5。如果您想使用 EF 5.0.0.0，则需要此版本的 .Net。
