SoftwareOSIndependence

Problem

• UI (***):
  • WPF: The user interface (desktop-user-interface-library from WindowsOS)
• API (*):
  • WinForms / Microsoft.Win32 / Windows‑APIs: OpenFileDialog, MessageBox, Microsoft.Win32, etc.
  • P/Invoke to Kernel32.dll:
    • Utils.cs declares DllImport("Kernel32.dll") GetSystemTimePreciseAsFileTime <- Works only on Windows.
  • Process.Start
  • System.Drawing.Bitmap requires native libgdiplus library on Linux/macOS <- Which is subject to limitations.
• Registry‑Accesses
• Shell‑Conventions
• Paths:
  • Hard-coded path/path separator assumptions and backslashes (e.g., sys.path.append(os.getcwd() + "\pythonModules")) <- Windows-centric.
  • Hard-coded Windows programs/paths (e.g., the Visual Studio path used to open files)."
  • Python interop (pythonnet): code sets Runtime.PythonDLL to e.g. @"python310" <— library names differ on Linux/macOS (e.g., libpython3.x.so / .dylib).

Needed for OS independence

• UI switch
  • (Avalonia, .NET MAUI, tkinter, ..)
• Platform‑abstractions:
  • Cross-platform .NET APIs: like Stopwatch.GetTimestamp() instead of GetSystemTimePreciseAsFileTime.
  • Path.Combine or Path.PathSeparator instead of backslashes.
• /Platform-conditionalizing:
  • conditional compilation and RuntimeInformation to gate Windows‑specific code:
    • if (RuntimeInformation.IsOSPlatform(OSPlatform.Windows)) { /* win-only */ }

Possability atm

• WINE (https://www.winehq.org/) for Linux/MacOS
  • (no documentation about it for BS3 yet, your help writing the article is welcome)
