EF Power Tools Beta 2：System.MissingMethodException由'Reverse Engineer Code First'抛出

Question

我已经安装了'Entity Framework Power Tools Beta 2'，我想简单地反转映射我的数据库模式。我右键单击解决方案资源管理器中的项目，然后单击“实体框架 - >反向工程师代码优先”，指定连接属性，并在输出窗口中出现以下错误。任何想法可能是错的？

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