error CS0246: The type or namespace name 'DescriptionAttribute' could not be found (are you missing a using directive or an assembly reference?)

If you had checked the documentation for the DescriptionAttribute class, you would have seen that it's in the System.ComponentModel namespace. --- b { font-weight: normal; }
