WPF Animated GIF

Nuget package available here: WpfAnimatedGif.

A simple library to display animated GIF images in WPF, usable in XAML or in code.

It's very easy to use: in XAML, instead of setting the Source property, set the AnimatedSource attached property to the image you want:

<Window x:Class="WpfAnimatedGif.Demo.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:gif="http://wpfanimatedgif.codeplex.com"
        Title="MainWindow" Height="350" Width="525">
    <Grid>
        <Image gif:ImageBehavior.AnimatedSource="Images/animated.gif" />

You can also specify the repeat behavior (the default is 0x, which means it will use the repeat count from the GIF metadata):

        <Image gif:ImageBehavior.RepeatBehavior="3x"
               gif:ImageBehavior.AnimatedSource="Images/animated.gif" />

And of course you can also set the image in code:

var image = new BitmapImage();
image.BeginInit();
image.UriSource = new Uri(fileName);
image.EndInit();
ImageBehavior.SetAnimatedSource(img, image);

See the wiki for more details on usage.

Features

Animates GIF images in a normal Image control; no need to use a specific control
Takes actual frame duration into account
Repeat behavior can be specified; if unspecified, the repeat count from the GIF metadata is used
Notification when the animation completes, in case you need to do something after the animation
Animation preview in design mode (must be enabled explicitly)
Support for controlling the animation manually (pause/resume/seek)

How to build

Run build.cmd.

Note: the library's version number is determined by MinVer based on Git history and tags. A consequence of this is that if you build the project outside a Git repository (e.g. if you just download sources), you'll get a version number of 0.0.0.0. So, in order to build with the correct version number, make sure you're in a Git clone of the project, and that your clone has the tags from the upstream project (git fetch upstream --tags, assuming your remote for the upstream project is named upstream).
