Summary:
The documentation page demonstrates a Windows bias in several areas. File and executable naming conventions (e.g., 'handler.exe') are Windows-centric and appear before or instead of Linux equivalents. Example directory structures and configuration files consistently use Windows-style executable names, and there are no explicit Linux or macOS command-line or file examples. The documentation does not provide parity in showing how to configure or run custom handlers on Linux (e.g., using './handler' or without the '.exe' extension), nor does it mention Linux-specific tools or patterns.
Recommendations:
- In all file and executable examples, show both Windows and Linux/macOS equivalents (e.g., 'handler.exe' for Windows, './handler' for Linux/macOS).
- In directory structure diagrams, include both 'handler.exe' and 'handler' to illustrate cross-platform deployment.
- In configuration file examples, clarify that 'defaultExecutablePath' should match the platform (e.g., 'handler.exe' on Windows, 'handler' on Linux/macOS).
- Add explicit Linux/macOS command-line examples where relevant (e.g., how to build and run the handler on Linux).
- Mention cross-platform considerations (such as file permissions on Linux, executable extensions, and case sensitivity) in relevant sections.
- Where tools are referenced (such as Azure Functions Core Tools), clarify that they are available on all platforms and provide installation/use instructions for Linux/macOS as well as Windows.
