If you are specifically connecting to a MS Sql database, this should work:

private DbConnection CreateConnection(string connectionString)
{
    return new SqlConnection(connectionString);
}

private string CreateConnectionString(string server, string databaseName, string userName, string password)
{
    var builder = new SqlConnectionStringBuilder
    {
        DataSource = server, // server address
        InitialCatalog = databaseName, // database name
        IntegratedSecurity = false, // server auth(false)/win auth(true)
        MultipleActiveResultSets = false, // activate/deactivate MARS
        PersistSecurityInfo = true, // hide login credentials
        UserID = userName, // user name
        Password = password // password
    };
    return builder.ConnectionString;
}

how to use:

public void ConnectoToDbWithEf6()
{
    using(var connection = CreateConnection(CreateConnectionString("server", "db", "you", "password")
    {
        using(var context = new YourContext(connection, true))
        {
            foreach(var someEntity in context.SomeEntitySet)
            {
                Console.WriteLine(someEntity.ToString());
            }
        }
    }

}
