Копать нужно в сторону XAML.

Пример вращения картинки при наведении курсора:

<Grid>
        <Image Height="62" HorizontalAlignment="Left" Margin="259,0,0,176" Stretch="Fill" VerticalAlignment="Bottom" Width="62" Source="Background.jpg" RenderTransformOrigin="0.5,0.5">
            <Image.RenderTransform>
                <RotateTransform x:Name="Povorot" Angle="0"/>
            </Image.RenderTransform>

            <Image.Triggers>
                <EventTrigger RoutedEvent="Button.MouseEnter">
                    <BeginStoryboard>
                        <BeginStoryboard.Storyboard>
                            <Storyboard>
                                <DoubleAnimation Duration="0:0:0.25" AutoReverse="False" Storyboard.TargetName="Povorot" Storyboard.TargetProperty="Angle" RepeatBehavior="Forever" From="0" To="200" />
                            </Storyboard>
                        </BeginStoryboard.Storyboard>
                    </BeginStoryboard>
                </EventTrigger>
                <EventTrigger RoutedEvent="Button.MouseLeave">
                    <BeginStoryboard>
                        <BeginStoryboard.Storyboard>
                            <Storyboard>
                                <DoubleAnimation Duration="0:0:0.25" Storyboard.TargetName="Povorot" Storyboard.TargetProperty="Angle" To="0" />
                            </Storyboard>
                        </BeginStoryboard.Storyboard>
                    </BeginStoryboard>
                </EventTrigger>
            </Image.Triggers>
        </Image>
    </Grid>
