使用Nuget加载包：EntityFramework，MySql.Data，MySql.Data.Entity
检查App.config或是web.config相关节点
1. EF配置节点
1 <configSections>
2 <section name=
"entityFramework" type=
"System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission=
"false" />
3 </configSections>
4 <entityFramework>
5 <defaultConnectionFactory type=
"System.Data.Entity.Infrastructure.LocalDbConnectionFactory, EntityFramework">
6 <parameters>
7 <parameter value=
"mssqllocaldb" />
8 </parameters>
9 </defaultConnectionFactory>
10 <providers>
11 <provider invariantName=
"System.Data.SqlClient" type=
"System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" />
12 <provider invariantName=
"MySql.Data.MySqlClient" type=
"MySql.Data.MySqlClient.MySqlProviderServices, MySql.Data.Entity.EF6, Version=6.9.9.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d"></provider></providers>
13 </entityFramework>
2. MySQL配置节点
1 <system.data>
2 <DbProviderFactories>
3 <remove invariant=
"MySql.Data.MySqlClient" />
4 <add name=
"MySQL Data Provider" invariant=
"MySql.Data.MySqlClient" description=
".Net Framework Data Provider for MySQL" type=
"MySql.Data.MySqlClient.MySqlClientFactory, MySql.Data, Version=6.9.9.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" />
5 </DbProviderFactories>
6 </system.data>
3. 连接字符串
1 <connectionStrings>
2 <add name=
"NorthwindConnection" connectionString=
"Data Source=localhost;port=3306;Initial Catalog=northwind;user id=developer;password=developer;"
3 providerName=
"MySql.Data.MySqlClient" />
4 </connectionStrings>
