我已在本地计算机上将 EntityFramework 从 4.1 升级到 5，并将 .NET Framework 升级到 4.5，一切正常，但是当我在 Azure 上发布我的更改时，我收到此错误：

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].

检查该程序集的项目引用。确保您已将该引用的属性上的 copy local 设置为 true。此外，升级 Azure SDK 和 EF 可能会影响项目引用的程序集版本。确保您的项目中也引用了正确的版本。

您是否正在部署到 Windows Server 2012 映像（我看到您使用的是 .NET 4.5）？如果您使用 Azure SDK 1.8 并且 OSVersion = 3（新 SDK 上的新云服务项目的默认设置）...

Windows Server 2012 没有启用 .NET 3.5 库，您必须启用该功能（我相信安装它）。您可能必须自动启用 .NET 3.5。
