But the problem remains.

It's important to note that your model validation takes into consideration the datatype of the fields. So fields like decimal or int are non-nullable. But you can solve this by declaring your fields as nullable. For such types, you don't need to declare [Required] because by their very nature they cannot be null unless declared nullable using ? operator.

Example:

public decimal? DiscountedProductPrice
