Webservice 一直引用旧版本的 entityframework

【问题标题】：Webservice keeps referencing to old version of entityframeworkWebservice 一直引用旧版本的 entityframework
【发布时间】：2014-02-04 07:17:22
【问题描述】：

我有一个 .NET 4.5 WCF 网络服务，它使用 Entityframwork 5.0.0 和 MySQL 连接器 6.7.4。 Web 服务在 localhost 上运行良好（即使从另一台计算机上使用），但是当我将其上传到服务器 (IIS) 时，尝试使用 Web 服务时出现以下错误：

»Could not load file or assembly 'EntityFramework, Version=4.4.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies.«

我找不到任何提到 EF 4.4.0.0 的地方。

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].

有什么想法吗？

【问题讨论】：

  • 你是否检查了应用程序池，与网站名称相关联的 .net 框架版本。

标签： c# mysql wcf web-services entity-framework


【解决方案1】：

我通常用 ILDASM.exe 打开所有的 .dll 和 .exe 文件并手动检查 MANIFEST。

【讨论】：

    【解决方案2】：

    一些行动建议：

    • 手动从服务器中删除旧版本。

    • 确认您确实发布了新版本的服务。

    • 验证服务器上的实际端点（IP、端口）是否绑定到特定服务。

    • 使用tool（如 ILDASM.exe）检查所有引用，包括所有引用的 dll 引用。

    希望我能帮上忙！
