How to connect MySql database using C# ?

for now i created:

public class EF5_DATABASE : DbContext
{
    public DbSet<Sistema.Clientes.Cliente> Clientes { get; set; }
}

but the following code is not working:

EF5_DATABASE db = new EF5_DATABASE();
db.Database.Connection = ERP.MyConnection;   // MyConnection is a connected MySqlConnection

it throws this compiler error:

    Error  8   Property or indexer 'System.Data.Entity.Database.DbDatabase.Connection' cannot be assigned to开发者_开发知识库 -- it is read only
    C:\inetpub\wwwroot\temp\WpfApplicationTEST\MainWindow.xaml.cs   48  13  WpfApplicationTEST

We have written an article illustrating some aspects of EF CTP 5 Code First support in dotConnect for MySQL.
Hope this article will be helpful.
