Answer 1

添加MySql.Data.dll作为项目的引用
将此块添加到web.config:

<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" />
    </DbProviderFactories>
</system.data> 

Answer 2

引用MySql.Data和MySql.Entities Nuget包.然后将此行添加到您的Web配置中.

<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=6.5.4.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" />
  </DbProviderFactories>
</system.data>

您的连接字符串应类似于以下内容:

<add name="MyDb" connectionString="Server=127.0.0.1;Port=3306;Database=MyDb;Uid=root;Pwd=;" providerName="MySql.Data.MySqlClient" />
