AvaloniaUI is essentially cross-platform WPF for .NET Core. It recently entered its beta phase. http://avaloniaui.net/ http://avaloniaui.net/ To be clear: * On top of Win32 and Direct2D for Windows. * On top of GTK3 and Skia for Linux. * On top of MonoMac (and Skia?) for macOS. * Experimental support for Android. * Experimental support for iOS. One can see Avalon Studio as a sort of proof of concept, an Avalonia-based IDE for C#, C++, and Core2D development. https://github.com/VitalElement/AvalonStudio https://github.com/VitalElement/AvalonStudio
