These are my files:
Effect: raw.githubusercontent.com/BogdanDimov/TechnicalChallengeProgress/master/TechnicalChallengeProgress/TechnicalChallengeProgress/Effects/ShadowEffect.cs
Android Effect: raw.githubusercontent.com/BogdanDimov/TechnicalChallengeProgress/master/TechnicalChallengeProgress/TechnicalChallengeProgress.Android/Effects/LabelShadowEffect.cs
Main Page: raw.githubusercontent.com/BogdanDimov/TechnicalChallengeProgress/master/TechnicalChallengeProgress/TechnicalChallengeProgress/Views/MainPage.xaml
I'm referring to following documentation: developer.xamarin.com/guides/xamarin-forms/application-fundamentals/effects/passing-parameters/attached-properties/
What am I doing wrong?
