Demo 1

• Full vector emoji! Render at huge sizes without quality loss.
• Optional support for subpixel antialiasing.
• Lightweight; does not embed a font or emoji images; just uses the system font.
• Works with old .NET versions such as .NET Framework 4.0.
• Can work on Windows 7 or Windows 8 by installing the Segoe UI Emoji font in c:/Windows/Fonts.
• Free, opensource software, with no strings attached.
• Available as a Nuget package.

• Emoji.Wpf.TextBlock: an emoji-aware version of System.Windows.Controls.TextBlock.
• Emoji.Wpf.RichTextBox: an emoji-aware version of System.Windows.Controls.RichTextBox.
• Emoji.Wpf.Picker: an emoji picker

• Emoji.Image.Source: attach to either System.Windows.Controls.Image control or System.Windows.Media.DrawingImage object in order to manipulate emoji images

• bool Emoji.Wpf.EmojiData.EnableSubPixelRendering: enable subpixel rendering, defaults to false
• bool Emoji.Wpf.EmojiData.EnableWindowsStyleFlags: enable flag rendering, defaults to autodetected

Here is how to use Emoji.Wpf in your XAML:

 <Window ...
 xmlns:emoji="clr-namespace:Emoji.Wpf;assembly=Emoji.Wpf"
 ...>
 <Window.Resources>
 <DrawingImage x:Key="MyImageSource" emoji:Image.Source="👻"/>
 </Window.Resources>
 ...
 <emoji:RichTextBox FontSize="24" Margin="5"/>
 ...
 <emoji:TextBlock FontSize="24" Text="Hello! 💖😁🐨🐱‍🐉👩🏿‍👩🏻‍👦🏽 lol"/>
 ...
 <emoji:Picker FontSize="40"/>
 ...
 <Image Source="{StaticResource MyImageSource}"/>
 ...
 <Image emoji:Image.Source="🦑"/>
 ...
 </Window>

More classes are to come, but feedback on what is needed is welcome.

I am not a very good WPF or even C# developer, but I think this could become a very useful and robust library if given enough care. Any help appreciated!
