Summary:
The documentation provides file path examples exclusively in Windows format (e.g., '@"c:\temp\media.jpg"'), with no mention of Linux or cross-platform file paths. There are no Linux or POSIX-style file path examples, and no guidance for users on non-Windows systems.
Recommendations:
- Include Linux/Unix-style file path examples (e.g., '/tmp/media.jpg') alongside Windows examples.
- Add a note explaining that file paths are platform-dependent and provide guidance for both Windows and Linux users.
- Consider using Path.Combine or similar cross-platform APIs in code examples to construct file paths in a platform-agnostic way.
- Explicitly mention cross-platform compatibility and test the code on both Windows and Linux environments.
