 - Example [ProductItemsList](./ECommerce/ShoppingCarts/ProductItems/ProductItemsList.cs) value object wrapping the list of product items in the shopping carts. It simplified the main state apply logic and offloaded some of the invariants checks.
 - All commands by convention should be created using the [factory method](./ECommerce/ShoppingCarts/AddingProductItem/AddProductItemToShoppingCart.cs#L13) to enforce the types,
 - Command handlers are defined as static methods in the same file as command definition. Usually, they change together. They are pure functions that take command and/or state and create new events based on the business logic. See sample [Adding Product Item to ShoppingCart](./ECommerce/ShoppingCarts/AddingProductItem/AddProductItemToShoppingCart.cs#L25). This example also shows that you can inject external services to handlers if needed.
