Hi,
I'm rewriting my project, so it's easier to edit in future, and want to implement interface.
I've implemented the interface, but it doesn't work in MainWindow, I'm not able to call the method.
So I've tried to use the PalindromeChecker as the default implementation PalindromeChecker = new PalindromeChecker(); , so I can call the method but it didn't work.
