Working with metaclass objects

Creating objects

DataContext.Current = new DataContext(ServiceLocator.Current.GetInstance<IConnectionStringHandler>().Commerce.ConnectionString);
ModuleManager.InitializeActiveModules();
using (var scope = DataContext.Current.MetaModel.BeginEdit(MetaClassManagerEditScope.SystemOwner, AccessLevel.System))
{
    var manager = DataContext.Current.MetaModel;
    var changeTrackingManifest = ChangeTrackingManager.CreateModuleManifest();
    var recentReferenceManifest = RecentReferenceManager.CreateModuleManifest();
    var budgetClass = manager.CreateMetaClass("Budget", "Budget", "Budgets", "cls_Budget", PrimaryKeyIdValueType.Integer);
    ModuleManager.Activate(budgetClass, changeTrackingManifest);
    using (var builder = new MetaFieldBuilder(budgetClass))
    {
        builder.CreateDateTime("StartDate", "StartDate", true, false);
        builder.CreateDateTime("EndDate", "EndDate", true, false);
        builder.CreateCurrency("Amount", "Amount", true, 0, true);
        builder.CreateText("Currency", "Currency", true, 50, false);
        builder.CreateText("Status", "Status", true, 50, false);
        builder.CreateCurrency("SpentBudget", "SpentBudget", true, 0, true);
        builder.CreateText("PurchaserName", "PurchaserName", true, 50, false);
        builder.CreateCurrency("LockOrganizationAmount", "LockOrganizationAmount", true, 0, true);
        var contactReference = builder.CreateReference("Contact", "CreditCard_mf_Contact", true, "Contact", false);
        var orgReference = builder.CreateReference("Organization", "CreditCard_mf_Organization", true, "Organization", false);
        builder.SaveChanges();
    }

    budgetClass.AddPermissions();
    scope.SaveChanges();
}

Editing objects

DataContext.Current = new DataContext(ServiceLocator.Current.GetInstance<IConnectionStringHandler>().Commerce.ConnectionString);
ModuleManager.InitializeActiveModules();
using (var scope = DataContext.Current.MetaModel.BeginEdit(MetaClassManagerEditScope.SystemOwner, AccessLevel.System))
{
    var manager = DataContext.Current.MetaModel;
    var contactMetaClass = manager.MetaClasses[ContactEntity.ClassName];
    var changeTrackingManifest = ChangeTrackingManager.CreateModuleManifest();
    var recentReferenceManifest = RecentReferenceManager.CreateModuleManifest();
    using (var builder = new MetaFieldBuilder(contactMetaClass))
    {
        builder.CreateText("UserRole", "{Customer:UserRole}", true, 50, false);
        builder.CreateText("UserLocation", "{Customer:UserLocation}", true, 50, false);
        builder.CreateInteger("Points", "{Customer:Points}", true, 0);
        builder.CreateInteger("NumberOfOrders", "{Customer:NumberOfOrders}", true, 0);
        builder.CreateInteger("NumberOfReviews", "{Customer:NumberOfReviews}", true, 0);
        builder.CreateText("Tier", "{Customer:Tier}", true, 100, false);
        builder.CreateText("ElevatedRole", "{Customer:ElevatedRole}", true, 100, false);
        builder.CreateHtml("Bookmarks", "{Customer:Bookmarks}", true);
        builder.SaveChanges();
    }
    contactMetaClass.DeleteMetaField("MiddleName");
    scope.SaveChanges();
}

Deleting objects

DataContext.Current = new DataContext(ServiceLocator.Current.GetInstance<IConnectionStringHandler>().Commerce.ConnectionString);
ModuleManager.InitializeActiveModules();
using (var scope = DataContext.Current.MetaModel.BeginEdit(MetaClassManagerEditScope.SystemOwner, AccessLevel.System))
{
    var manager = DataContext.Current.MetaModel;
    manager.DeleteMetaClass("CreditCard");
    scope.SaveChanges();
}
