Platform-Specific Notes

Windows

Will use WPF backend when Eto.Platform.Wpf package is installed.

macOS

Will use Cocoa backend when Eto.Platform.Mac64 package is installed.

Original Legacy Project

The original Windows-only version can be found in the FocusBar.Old/ directory:

• FocusBar.Old/FocusBarWin/ - Legacy WinForms application
• FocusBar.Old/ShellBasics/ - Legacy Windows Shell integration library
• FocusBar.Old/FocusBarWin.sln - Legacy Visual Studio solution

This legacy code used Windows Shell APIs for desktop toolbar functionality and was limited to Windows only.
