mysql - 带有 MySQL 的 Entity Framework

Question

我收到以下错误

“ Entity Framework 提供程序类型‘MySql.Data.MySqlClient.MySqlProviderServices，MySql.Data.Entity’在应用程序配置文件中注册，无法加载具有固定名称‘MySql.Data.MySqlClient’的 ADO.NET 提供程序。确保使用程序集限定名称并且程序集可用于正在运行的应用程序。有关详细信息，请参阅 http://go.microsoft.com/fwlink/?LinkId=260882。”

但是我确实在我的项目中引用了 MySql.Data.dll 和 MySql.Data.Entity.dll 以及 MySql.Data.Entity.EF6.dll(来自 MySQL Connector Net 6.8.3)

这是我的 App.conf

<?xml version="1.0" encoding="utf-8"?>
 <configuration>
  <configSections>
   <!-- For more information on Entity Framework configuration, visit  http://go.microsoft.com/fwlink/?LinkID=237468 -->

</entityFramework>
</configuration>

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <configSections>
    <!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 -->
    <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />

  <connectionStrings>
    <add name="inspectm_inspectContext" connectionString="server=--;user id=--;password=--;database=--;persistsecurityinfo=True" providerName="MySql.Data.MySqlClient" />
  </connectionStrings>
  <entityFramework>
    <defaultConnectionFactory type="System.Data.Entity.Infrastructure.SqlConnectionFactory, EntityFramework" />
     <providers>
      <provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" />
      <provider invariantName="MySql.Data.MySqlClient" type="MySql.Data.MySqlClient.MySqlProviderServices, MySql.Data.Entity.EF6, Version=6.8.3.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d"></provider>
     </providers>
  </entityFramework>
</configuration>

我的完整 App.conf 这对我有用

首先我删除了

<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=6.7.4.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" />
</DbProviderFactories>

然后我变了

<defaultConnectionFactory type="MySql.Data.MySqlClient.MySqlClientFactory, MySql.Data" />

并添加了提供者

<provider invariantName="MySql.Data.MySqlClient" type="MySql.Data.MySqlClient.MySqlProviderServices, MySql.Data.Entity.EF6, Version=6.8.3.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d"></provider>
