我安装了“Entity Framework Power Tools Beta 2”，我想简单地反向映射我的数据库模式。我在解决方案资源管理器中右键单击该项目，然后单击“实体框架-> 逆向工程代码优先”，指定连接属性，然后在输出窗口中出现以下错误。知道有什么问题吗？

System.MissingMethodException: Method not found: 'System.Xml.XmlReader System.Data.Common.DbProviderServices.GetConceptualSchemaDescription()'.

看起来实体框架 2011 年 6 月 CTP 已安装在您的盒子上。你需要卸载它。在此处查看更多详细信息：http: //blog.3d-logic.com/2012/04/11/entity-framework-zombie-aka-microsoft-entity-framework-june-2011-ctp/
