Display gif image - wpf

Question

When I developed my WPF PC application, I used the following code to display my gif image, as I realized that there is no easy way of doing this:-
XAML:
<StackPanel Height="25" Name="stkProgressBar">
<wfi:WindowsFormsHost Background="Transparent" HorizontalAlignment="Center">
<winForms:PictureBox x:Name="pictureBoxLoading" Visible="False">
</winForms:PictureBox>
</wfi:WindowsFormsHost>
</StackPanel>
XAML.cs:
private void Page_Loaded(object sender, RoutedEventArgs e)
{
this.pictureBoxLoading.Image = Properties.Resources.progressbar;
}
Now when I use the same approach to display the image in my WPF Browser (XBAP) application, it is not loading the page because of this xaml code? Any ideas why is that so and if there is any other way to display GIFs on a XBAP page?
Thanks,
Abhi.

Now I tried the following code:-
XAML:
<Image Name="Image1"></Image>
XAML.cs:
Stream imageStreamSource = new FileStream(#"C:\Inetpub\ExchangeRate\ExchangeRate\Image\progressbar.gif", FileMode.Open, FileAccess.Read, FileShare.Read);
GifBitmapDecoder decoder = new GifBitmapDecoder(imageStreamSource, BitmapCreateOptions.PreservePixelFormat, BitmapCacheOption.Default);
Int32Animation anim = new Int32Animation(0, decoder.Frames.Count - 1, new Duration(new TimeSpan(0, 0, 0, decoder.Frames.Count / 10, (int)((decoder.Frames.Count / 10.0 - decoder.Frames.Count / 10) * 1000))));
anim.RepeatBehavior = RepeatBehavior.Forever;
BitmapSource bitmapSource = decoder.Frames[0];
Image1.Source = bitmapSource;
Image1.Stretch = Stretch.None;
It shows the image alright, but is not animated. I would appreciate any help in this regard.

After toiling for a day I worked it out using a different approach. Instead of using a gif image, I created a user control as follows:-
<UserControl.Resources>
<Color x:Key="FilledColor" A="255" B="112" R="147" G="160"/>
<Color x:Key="UnfilledColor" A="0" B="112" R="147" G="160"/>
<Storyboard x:Key="Animation0" FillBehavior="Stop" BeginTime="00:00:00.0" RepeatBehavior="Forever">
<ColorAnimationUsingKeyFrames Storyboard.TargetName="_00" Storyboard.TargetProperty="(Shape.Fill).(SolidColorBrush.Color)">
<SplineColorKeyFrame KeyTime="00:00:00.0" Value="{StaticResource FilledColor}"/>
<SplineColorKeyFrame KeyTime="00:00:01.6" Value="{StaticResource UnfilledColor}"/>
</ColorAnimationUsingKeyFrames>
</Storyboard>
<Storyboard x:Key="Animation1" BeginTime="00:00:00.2" RepeatBehavior="Forever">
<ColorAnimationUsingKeyFrames Storyboard.TargetName="_01" Storyboard.TargetProperty="(Shape.Fill).(SolidColorBrush.Color)">
<SplineColorKeyFrame KeyTime="00:00:00.0" Value="{StaticResource FilledColor}"/>
<SplineColorKeyFrame KeyTime="00:00:01.6" Value="{StaticResource UnfilledColor}"/>
</ColorAnimationUsingKeyFrames>
</Storyboard>
<Storyboard x:Key="Animation2" BeginTime="00:00:00.4" RepeatBehavior="Forever">
<ColorAnimationUsingKeyFrames Storyboard.TargetName="_02" Storyboard.TargetProperty="(Shape.Fill).(SolidColorBrush.Color)">
<SplineColorKeyFrame KeyTime="00:00:00.0" Value="{StaticResource FilledColor}"/>
<SplineColorKeyFrame KeyTime="00:00:01.6" Value="{StaticResource UnfilledColor}"/>
</ColorAnimationUsingKeyFrames>
</Storyboard>
<Storyboard x:Key="Animation3" BeginTime="00:00:00.6" RepeatBehavior="Forever">
<ColorAnimationUsingKeyFrames Storyboard.TargetName="_03" Storyboard.TargetProperty="(Shape.Fill).(SolidColorBrush.Color)">
<SplineColorKeyFrame KeyTime="00:00:00.0" Value="{StaticResource FilledColor}"/>

</Storyboard>
<Storyboard x:Key="Animation4" BeginTime="00:00:00.8" RepeatBehavior="Forever">

<SplineColorKeyFrame KeyTime="00:00:01.6" Value="{StaticResource UnfilledColor}"/>
</ColorAnimationUsingKeyFrames>
</Storyboard>
<Storyboard x:Key="Animation6" BeginTime="00:00:01.2" RepeatBehavior="Forever">
<ColorAnimationUsingKeyFrames Storyboard.TargetName="_06" Storyboard.TargetProperty="(Shape.Fill).(SolidColorBrush.Color)">
<SplineColorKeyFrame KeyTime="00:00:00.0" Value="{StaticResource FilledColor}"/>
<SplineColorKeyFrame KeyTime="00:00:01.6" Value="{StaticResource UnfilledColor}"/>
</ColorAnimationUsingKeyFrames>
</Storyboard>
<Storyboard x:Key="Animation7" BeginTime="00:00:01.4" RepeatBehavior="Forever">

<!-- <TextBlock Grid.Row="2" Grid.Column="0" Grid.ColumnSpan="3" Foreground="#AAA" TextAlignment="Center" FontSize="15" Text="{Binding Source={StaticResource Model}, Path=StatusMessage}"/> -->
</Grid>
In the usercontrol class, I created method as follows:-
public void Show()
{
this.Visibility = Visibility.Visible;
}
public void Hide()
{
this.Visibility = Visibility.Hidden;
}
This link pointed me in this direction.
