Avalonia Cross-Platform File Manager

I need an experienced C# developer who already feels at home with Avalonia to build a lightweight file-management desktop app that runs smoothly on both macOS and Windows. All core file operations—browsing local drives, copying, moving, renaming and deleting items, plus drag-and-drop support—should work natively on each platform and follow their respective UX conventions. I’ll be doing most of my testing on a Mac, so the project must compile and launch there first, but the same codebase should also publish cleanly for Windows without manual tweaks. Please keep the solution framework-agnostic beyond Avalonia and .NET so future Linux support remains an option. Deliverables • Clean, well-commented source in a Git repo • Cross-platform build scripts or CI pipeline that produce a signed .dmg for macOS and an installer or self-contained folder for Windows • A brief README explaining project structure, build steps and how to extend the UI Acceptance criteria • Out-of-the-box file operations behave identically on macOS and Windows • No unhandled exceptions during normal use; all errors surfaced through friendly dialogs • High-dpi icons and keyboard shortcuts mapped to each OS standard If this sounds straightforward to you and you’ve shipped Avalonia apps before, let’s get started.
