Prijavljuje mi problem, kaze da li vam nedostaje kastovanje...
Error 1 Cannot implicitly convert type 'Subclassing.Dog' to 'Subclassing.Rottweiler'. An explicit conversion exists (are you missing a cast?) D:\Documents and Settings\LIVADA\Local Settings\Application Data\Temporary Projects\ConsoleApplication1\Program.cs 12 32 ConsoleApplication1
Neko objasnjenje?
