I just released new version 1.6.5 of Empty Keys UI library. There is new beta support for Paradox engine 1.1b. You can download it for free on http://emptykeys.com.
Empty Keys UI is XAML based multi-platform, engine agnostic UI library. It comes with UI Generator. Final code is generated from standard XAML (.NET WPF) so you can use Visual Studio, Blend (or any other XAML editor) to create your UI. There is over 30 controls, support for brushes, shapes and animations.
It supports Data Binding and it was implemented to use with MVVM design pattern.
Thanks for any feedback
