Hi

I'm needing to add a few properties along with a product. They have no price associated with them and aren't nodes in Umbraco with a price, so don't think I can add them as a bundle.

Reading this, i can add properties to an Order https://vendr.net/docs/core/1-2-0/key-concepts/properties/#order-line-system-properties

But not sure how to programmatically add properties to a product/order line?

These product properties are configured on the front end and just needed adding to the product in the basket as reference.

I have so far:

 [HttpPost]
    public ActionResult AddToCart(AddToCartDto postModel)
    {

        try
        {
            using (var uow = _unitOfWorkProvider.Create())
            {
                var store = CurrentPage.GetStore();
                var order = _sessionManager.GetOrCreateCurrentOrder(store.Id)
                    .AsWritable(uow)
                    .AddProduct(postModel.ProductReference, postModel.Quantity);

                //add product properties to product <-----


                _orderService.SaveOrder(order);

                uow.Complete();
            }
        }
        catch(ValidationException)
        {
            ModelState.AddModelError("productReference", "Failed to add product to cart");
            return CurrentUmbracoPage();
        }

        TempData["addedProductReference"] = postModel.ProductReference;

        return RedirectToCurrentUmbracoPage();


    }

In TC I think we could add them as hidden inputs, is this still the case in Vendr? Or best to add it via ActionResult form post?
