Vista - System.InvalidOperationException

Hello
I have created a WPF web application . The same WPF application works
fine as a windows application but inside browser it gives the
exception. :

System.InvalidOperationException: The Storyboard.TargetProperty path
'(0).(1).[0]' does not point to a DependencyProperty.

This exception is removed if I comment the following code from my file
:

<!--<EventTrigger.Actions>
<BeginStoryboard>
<Storyboard>
<DoubleAnimation
Storyboard.TargetName="HighlightRectangle"
Storyboard.TargetProperty="(Rectangle.Fill).(LinearGradientBrush.GradientStops)[0]"
To="0.5" Duration="0:0:0.25"/>
<DoubleAnimation
Storyboard.TargetName="HighlightRectangle"
Storyboard.TargetProperty="(Rectangle.Fill).(LinearGradientBrush.GradientStops)[1]"
To="1" Duration="0:0:0.25"/>
</Storyboard>
</BeginStoryboard>
</EventTrigger.Actions>-->

Any help?

(Rectangle.Fill).(LinearGradientBrush.GradientStops)[0] is a GradientStop,
not a Double, and you can't directly animate a member of a collection,
because collection[i] is not a DependencyProperty (you can certainly animate
properties *on* elements of a collection). You probably need to have a path
of
(Rectangle.Fill).(LinearGradientBrush.GradientStops)[0].(GradientStop.Offset).
