c# – System.data.Sqlite與EF6

我正在開發一個涉及將SQLite與EF 6連線在一起的資料庫優先方法的專案.我已經安裝了System.Data.SQLite(並確保它們的DLL在GAC中),並使用NuGet將依賴項新增到我的專案.但是,當我嘗試為已經存在的資料庫建立一個模式(通過實體資料模型嚮導)時,我收到錯誤

Your project references the latest version of Entity Framework; however, an Entity Framework database provider compatible with this version could not be found for your data connection. Exit this wizard, install a compatible provide, and rebuild your project before performing this action.

我在ofollow,noindex" target="_blank">this thread 嘗試過答案,但是沒有涉及到用手建立DAO類的修補程式似乎沒有幫助.由於我連線到的資料庫相當大(在架構上),因此在程式碼中重新構建模式對我來說是不合理的.

我的App.config如下.

<?xml version="1.0" encoding="utf-8"?>
<configuration>
<configSections>
<section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />

</DbProviderFactories>
</system.data>
</configuration>

我完全不瞭解VS所抱怨的內容,因為看起來System.Data.SQLite已經將其自身繫結到VS中,並且配置檔案包含允許VS找到它訪問資料庫的必要資訊.但是,我錯過了一些東西,我無法弄明白什麼.

THIS 專案也引用了與我自己相同的配置.
