 Open source  [application framework](https://en.wikipedia.org/wiki/Application_framework) for building portable graphical interfaces in **C#**, featuring a ***declarative language*** for ui with ***styling*** and ***templates*** called [IML](interface-markup-language) similar to [XAML](https://en.wikipedia.org/wiki/Extensible_Application_Markup_Language) and a ***binding system*** for easy code linking.
