Bias Analysis

Detected Bias Types

windows_first

powershell_heavy

windows_tools

Summary

The documentation demonstrates a Windows-first bias in the .NET/C# section by presenting Windows/PowerShell/ETW instructions before Linux/dotnet-trace equivalents. It also references Windows-specific tools (Event Tracing for Windows, PowerShell scripts) and provides more detailed, step-by-step instructions for Windows users. Linux instructions are present but appear after the Windows section, and the Windows approach is given more prominence.

Recommendations

Present Linux and Windows instructions in parallel or in a unified table, rather than listing Windows first.
Ensure both platforms receive equally detailed, step-by-step instructions and troubleshooting notes.
Where possible, use cross-platform tools or highlight them first if available.
Avoid referencing Windows-only tools (like ETW and PowerShell scripts) without offering equivalent Linux-native alternatives or context.
Explicitly state platform support in each section and avoid implying Windows is the default or primary environment.
