我已经创建了一个安装项目并安装在本地机器上。应用程序打开，但没有连接到数据库，它抛出如下屏幕截图错误。我正在使用 Entity Framework 4.0 但它要求 EntityFramework 4.4.0 不知道为什么？我已经使用框架 4.0 默认构建了这个设置，并在项目中使用了一些 devexpress 和 telerik 工具。

注意：他们没有提到实体 4.4，但它仍然要求 4.4 任何想法？但是对 4.0 的引用是他们在配置文件中的。

听起来您以某种方式设法丢失了 EF 引用，可能是由于意外添加了 .net 4.5 版本的程序集。

解决此问题的最简单方法是进入 nuget 并卸载 EF 5，然后重新安装它。这将使 nuget 将其读取到您的解决方案中并正确设置项目引用。
