I\'m getting the error \"Cannot implicitly convert type \'int?\' to \'int\'. An explicit conversion exists (are you missing a cast?)\" on my OrdersPerHour at the return line
Check the declaration of your variable. It must be like that
public Nullable x {get; set;} public Nullable y {get; set;} public Nullable z {get { return x*y;} }
I hope it is useful for you
