Не удается найти статический член «ThumbnailSourceProperty» в типе «CcsThumbnailDisplay»

Question

Я конвертирую код из Silverlight в WPF, но я хочу, чтобы приложение впоследствии работало в обоих. Поэтому я связываю файлы silverlight с новыми проектами wpf. Я получаю эту ошибку, когда я преобразовать его в проект WPF:

Ошибка 1 Не удается найти статический член «ThumbnailSourceProperty» на «CcsThumbnailDisplay» типа. C: \ Users \ sahluwai \ Desktop \ cusControls2 \ Leitch \ HarrisSilverlightToolkit \ Toolkit \ Source \ Controls \ DisplayControls \ Streaming \ Themes \ CcsThumbnailDisplay.xaml 22 109 DisplayControls

Существуют соглашения об именах для свойств зависимостей. Переименование ImageSourceProperty - ThumbnailSourceProperty:

public static readonly DependencyProperty ThumbnailSourceProperty = 
    DependencyProperty.Register("ThumbnailSource", ...); 

public ImageSource ThumbnailSource 
{ 
    get { return (ImageSource)GetValue(ThumbnailSourceProperty); } 
    set { SetValue(ThumbnailSourceProperty, value); } 
}
