How to connect it to a Wampserver MySQL database? I have connected the db to my project with

1. You will need to create a connection string called QfDefaultConnection in your app or web.config.
2. specify the ADO provider MySql (providerName="MySql.Data.MySqlClient") are supported. This data source will be used at design time to retrieve the schema. At runtime.
3. you need to supply a class, QfRuntimeConnection, with a static method GetConnection(). You must supply this class, but you can always manage the connection yourself if you have other ideas. The compiler will show you the way !

Here is a sample for your reference.

Answer 2

In your app.config, you'll need a connection string like this...

<add name="QfDefaultConnection" connectionString="Server=localhost;Database=dbname;Uid=root;Pwd=Dimosoftware=1;AllowUserVariables=True;" providerName="MySql.Data.MySqlClient"></add>

and code...

using System;
using System.Configuration;
using System.Data;
using MySql.Data.MySqlClient;

namespace YourApp
{
    class QfRuntimeConnection
    {
        public static IDbConnection GetConnection()
        {
            return new MySqlConnection(ConfigurationManager.ConnectionStrings["QfDefaultConnection"].ConnectionString);
        }
    }
}
