Я устанавливаю для кнопки следующий стиль:
<Style x:Key="CustomButtonStyle1" TargetType="Button">
<Setter Property="Background" Value="Transparent"/>
<Setter Property="BorderBrush" Value="{StaticResource PhoneForegroundBrush}"/>
<Setter Property="Foreground" Value="{StaticResource PhoneForegroundBrush}"/>
<Setter Property="BorderThickness" Value="{StaticResource PhoneBorderThickness}"/>
<Setter Property="FontFamily" Value="{StaticResource PhoneFontFamilySemiBold}"/>
<Setter Property="FontSize" Value="{StaticResource PhoneFontSizeMediumLarge}"/>
<Setter Property="Padding" Value="10,3,10,5"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Button">
<Grid Background="Transparent">
<VisualStateManager.VisualStateGroups>
<VisualStateGroup x:Name="CommonStates">
<VisualState x:Name="Normal"/>
<VisualState x:Name="MouseOver"/>
<VisualState x:Name="Pressed" />
<VisualState x:Name="Disabled"/>
<Storyboard>
<ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Foreground" Storyboard.TargetName="ContentContainer">
<DiscreteObjectKeyFrame KeyTime="0" Value="White"/>
</ObjectAnimationUsingKeyFrames>

<ImageBrush ImageSource="Images/aaa2.png"/>
</DiscreteObjectKeyFrame.Value>
</DiscreteObjectKeyFrame>
</ObjectAnimationUsingKeyFrames>
</Storyboard>
</VisualStateGroup>
</VisualStateManager.VisualStateGroups>
<Border x:Name="ButtonBackground" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" CornerRadius="0" Margin="{StaticResource PhoneTouchTargetOverhang}">

</Border>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Однако я получаю следующую ошибку, которую не знаю, как ее исправить:
Ошибка1 Не удается добавить экземпляр типа «System.Windows.Media.Animation.Storyboard» в коллекцию типа «MS.Internal.! VisualStateCollection».[Строка: 23 Позиция: 17]
Кнопка определяется следующим образом:
<StackPanel Orientation="Horizontal" HorizontalAlignment="Center" Margin="0,30,0,0">
<Button Name="aaa" Width="200" Content="aaa" Margin="0,0,-10,0" Click="aaa_Click" BorderThickness="0" BorderBrush="{x:Null}" Height="91" Foreground="Black" Style="{StaticResource CustomButtonStyle1}">
<Button.Background>
<ImageBrush ImageSource="../Images/aaa.png"/>
</Button.Background>
</Button>
