mysql - 提供者 Entity Framework MySQL 中出现错误

Question

我尝试连接 MySQL 数据库中的 Entity Framework ，但是当我连接时发生此错误

No Entity Framework provider found for the ADO.NET provider with invariant name 'MySql.Data.MySqlClient'. Make sure the provider is registered in the 'entityFramework' section of the application config file. See http://go.microsoft.com/fwlink/?LinkId=260882 for more information.

这是我的类库实体的 appConfig

<?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" />
</configSections>
<connectionStrings>
<add name="portallentesContext" connectionString="server=******;User Id=******;password=*********;Persist Security Info=True;database=portallentes"
  providerName="MySql.Data.MySqlClient" />
</connectionStrings>
<system.data>
<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=6.6.4.0" />
</DbProviderFactories>
</system.data>

<entityFramework>
<providers>
  <provider invariantName="MySql.Data.MySqlClient" type="MySql.Data.MySqlClient.MySqlClientFactory, MySql.Data, Version=6.6.4.0" >
  </provider>
</providers>
</entityFramework>
</configuration>

将MySql.Data.Entity.EF5.dll和MySql.Data.Entity.EF6.dll一起复制到bin目录下。
