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

Question

我已經安裝了'Entity Framework Power Tools Beta 2'，我想簡單地反轉映射我的數據庫模式。我右鍵單擊解決方案資源管理器中的項目，然後單擊「實體框架 - >反向工程師代碼優先」，指定連接屬性，並在輸出窗口中出現以下錯誤。任何想法可能是錯的？

System.MissingMethodException: Method not found: 'System.Xml.XmlReader System.Data.Common.DbProviderServices.GetConceptualSchemaDescription()'. 
    at System.Data.Entity.Design.EntityStoreSchemaGenerator.GetProviderSchemaMetadataWorkspace(DbProviderServices providerServices, DbConnection providerConnection) 
    at System.Data.Entity.Design.EntityStoreSchemaGenerator.CreateStoreSchemaConnection(String providerInvariantName, String connectionString) 
    at System.Data.Entity.Design.EntityStoreSchemaGenerator..ctor(String providerInvariantName, String connectionString, String namespaceName) 
    at Microsoft.DbContextPackage.Handlers.ReverseEngineerCodeFirstHandler.ReverseEngineerCodeFirst(Project project)
