Bias Analysis

Summary
The documentation demonstrates a bias toward Windows environments. Troubleshooting steps and examples are almost exclusively focused on ASP.NET/ASP.NET Core (C#), with no mention of Linux-specific tools or patterns. Diagnostic instructions reference Windows-centric tools (e.g., Fiddler, Performance Monitor), and debugging steps assume Visual Studio or Windows workflows. There are no Linux command-line or open-source alternatives provided, nor are there any Bash or Linux-native code/configuration samples.
Recommendations
  • Add Linux-specific troubleshooting instructions, such as using curl, tcpdump, or Wireshark for network diagnostics.
  • Include examples of viewing logs and debugging on Linux (e.g., using journalctl, systemd, or dotnet CLI tools).
  • Mention cross-platform tools (e.g., Wireshark, mitmproxy) alongside or instead of Windows-only tools like Fiddler.
  • Provide code/configuration samples for Linux environments, such as configuring .NET Core apps on Linux, or using environment variables instead of web.config.
  • When listing tools or steps, present cross-platform or Linux-first options before or alongside Windows-specific ones.
  • Reference Linux container diagnostics more thoroughly, including commands and links to relevant documentation.
