Majorsilence.Forms is a cross-platform WinForms library for .NET — a Windows Forms compatibility layer that moves legacy and modern WinForms applications onto a modern stack. Keep the Forms, controls, event handlers, and *.Designer.cs files you already have — run on Linux, run on macOS, and run on Windows from one build, with mobile and web within reach through Avalonia’s own Android, iOS, and Browser targets or through Uno Platform.
