1, 22 Steps for recommended Practice

1. Place the MySql.Data.dll under the Bin directory, or install the Mysql-connector-net-6.0.0.msi

2.web.config Add the following nodes, the registration version number is consistent

<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=6.0.0.0, Culture=neutral, Publickeytoken=c5687fc88969c44d "/>
</DbProviderFactories>
</system.data>

3. Global configuration

In C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\CONFIG, there is a field in Machine.config (XML file) that is <DbProviderFactories> There are entries written to the MySQL Data Provider,

If it is. NET 4.0, you need to manually change the Machine.config file. It's OK to copy the section below the v2.0.50727.

Add registration, <name= "SqlClient data Provider" > or <name= "MySQL data Provider" >

<system.data>

<DbProviderFactories>
