问题


I can't create an animation, or customize a color in ContentPresenter (NormalTextDay), this error appears in my XAML:

'System.Windows.Media.Animation.ColorAnimation' animation object can not be used to animate property 'Foreground' it is because of incompatible type 'System.Windows.Media.Brush

Not quite sure... but you might need to change this:

Storyboard.TargetProperty="(TextBlock.Foreground).(SolidColorBrush.Color)"

to this:

Storyboard.TargetProperty="(TextBlock.Foreground).Color"

as in this syntax "Foreground" and "SolidColorBrush" are the same object you seem to be duplicating it.
