mysql - 如何使用 MySQL 配置 MvcMusicStore .Net WebApp？

Question

我完全迷路了。我正在尝试使用 MySQL 设置 MvcMusicStore .Net 应用程序（http://mvcmusicstore.codeplex.com/），但是在编译项目时出现了几个错误；

我已经阅读了http://dev.mysql.com上关于使用 .Net Entity Framework 和 MySQL 的文档，但是我是 EF 的初学者，这些是我没有成功的步骤：

我已经安装了 MySQL Server 5.5
在http://mvcmusicstore.codeplex.com/downloads/get/238258下载了 MvcMusicStore
安装 MySQL Connector Net 6.4.4 并在 mysql 中创建 db: CREATE DATABASE mvcmusicstore/*!40100 CHARACTER SET utf8 COLLATE utf8_general_ci */;
添加了对项目 MvcMusicStore 的以下引用：mysql.data，（未添加 mysql.data.cf 或我收到错误），mysql.data.entity，mysql.web（对于每个库，在属性中，选择“true”复制bin文件夹中的dll）

在“web.config”中替换：

<connectionStrings>
<add name="MusicStoreEntities"
connectionString="Data Source=|DataDirectory|MvcMusicStore.sdf"
providerName="System.Data.SqlServerCe.4.0"/>
</connectionStrings>

和：

    <connectionStrings>
    <add name="MusicStoreEntities"
    connectionString="Server=127.0.0.1; Database=mvc_store; Uid=root; Pwd={* my password *};"
    providerName="MySQL Data Provider" />
    </connectionStrings>
    <system.data>
    <DbProviderFactories>
    <add name="MySQL Data Provider"
    invariant="MySql.Data.MySqlClient"
    description=".Net Framework Data Provider for MySQL"
    type="MySql.Data.MySqlClient.MySqlClientFactory, MySql.Data, Version=6.4.4.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" />
    </DbProviderFactories>
    </system.data>

清理项目->编译并重新编译，然后我收到错误：

“为 system.data 创建配置节处理程序时出错：列 'InvariantName' 被限制为唯一。值 'MySql.Data.MySqlClient' 已经存在。”

所以我已经用如何首先使用 MySql 和实体框架 4.1 代码中找到的代码替换了“dbproviderfactories”部分

    <DbProviderFactories>
    <remove invariant="MySql.Data.MySqlClient" />
    <add name="MySQL Data Provider" 
    invariant="MySql.Data.MySqlClient" 
    description=".Net Framework Data Provider for MySQL"
    type="MySql.Data.MySqlClient.MySqlClientFactory, MySql.Data, Version=6.4.4.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" />
    </DbProviderFactories>

重新编译，然后我得到错误“找不到数据提供者”：

Details: 
ArgumentException: Can not find the data provider. Net Framework required. It may not be installed.

Error in the source code: 

Row 17:         ' the albums with the highest count

我不知道该怎么做才能解决它。

您还记得在您的项目中添加对 MySQL 连接器的引用吗？
