i want to create data base by using c++ language what i'm suppossed to do efore starting

public indigoDBContext() : base("DefaultConnection")
{
    // Enable the Intializer
    Database.SetInitializer(new indigoIntializer());
}

class indigoIntializer : CreateDatabaseIfNotExists<indigoDBContext>
{
    protected override void Seed(indigoDBContext context)
    {
        base.Seed(context);

<pre>
    // Seed the Website Adminsitrator Table
    siteAdministrators.seed(context);

    // Seed the Website Countries and States
    countries.seed(context);
    states_Provinces.seed(context);
    salesTax.seed(context);
    avatars.seed(context);
    themes.seed(context);
    paymentGateways.seed(context);
    paymentBrands.seed(context);

}

internal sealed class Configuration : DbMigrationsConfiguration<Indigo.DataAccessLayer.indigoDBContext>
{
    public Configuration()
    {
        AutomaticMigrationsEnabled = true;
    }

    protected override void Seed(Indigo.DataAccessLayer.indigoDBContext context)
    {
        base.Seed(context);

        // Seed the Website Adminsitrator Table
        siteAdministrators.seed(context);

    }
}
