Bias Analysis
Bias Types:
⚠️
windows_first

missing_linux_example
Summary:
The documentation page shows a Windows bias by using Windows-specific device IDs (e.g., 'Windows109') in all JSON examples and not providing any Linux-based examples or references. There are no explicit Linux commands, device names, or screenshots, and the only sample module client code references .NET (commonly associated with Windows, though cross-platform). No mention is made of Linux tools, patterns, or device names, and the examples and walkthroughs implicitly assume a Windows environment.
Recommendations:
- Include examples with Linux-based device IDs (e.g., 'Ubuntu2004', 'raspberrypi', etc.) alongside or instead of Windows IDs in JSON samples.
- Explicitly mention that the instructions and tools (Azure CLI, VS Code, Azure Portal) are cross-platform and work on Linux, macOS, and Windows.
- Add screenshots or terminal snippets from Linux environments where appropriate.
- If referencing code samples, consider including examples in Python or Node.js (popular on Linux) in addition to .NET.
- Clarify that the steps and troubleshooting guidance apply equally to Linux-based IoT Edge devices.
- Where possible, provide Linux-specific troubleshooting tips or notes (e.g., file paths, service management commands).
