XamlXporter is a project I undertook (mostly as a pet project) to re-create what Michael Swanson did with his Illustrator Plugin. In other words, XamlXporter allows you to export your Illustrator artwork into WPF/XAML format. The exporter has been written entirely in C#, .Net 2.0 with a WinForms UI. It uses the Adobe Illustrator CS2 COM Type Library to talk to Illustrator. More information can be found on this earlier blog post.
I have updated this app to support a few extra features:
The output with DrawingBrush chosen looks something like this. Note the nice formatting ;-)
Feel free to use this library/app in your own projects. Get the source and binaries from the project page:
