我想在MySQL數據庫中查詢一些用戶 - 當然，當我獲取包引用EntityFramework並使用MySQL連接器時，它們被更新爲現在版本6.0。這個LINQ查詢當我在VS 2012 IDE中使用MySQL數據連接器在幾個月前運行Entity Framework 5.0時，我一直在練習正常工作。C＃.NET 4.5實體框架6.0 MySQL數據適配器組裝
然而，在我的WPF應用程序，當我剛開始通過相應的實體查詢數據庫，我收到以下錯誤：
Could not load file or assembly 'MySql.Data.Entity.EF6, Version=6.9.8.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)
我剛開始這周成建這個WPF應用程序。有什麼我失蹤？這是我的代碼到目前爲止，其配置文件。
的app.config：

這裏還有爲那些需要看得太窗口的XAML：
