dotnet-cross-platform

Guides cross-platform .NET development by preferring framework APIs over shell commands and isolating OS-specific code in a single helper class. Load when writing code that must run on both macOS and Windows.

npx claudepluginhub dreamteam-hq/brigid --plugin dt-brigid

Tool Access

This skill uses the workspace's default tool permissions.

Preview

Use `System.Diagnostics.Process` and `System.Net.NetworkInformation` before reaching for `ps`, `lsof`, `wmic`, or `netstat`. Only shell out when no .NET API exists.

Cross-Platform Patterns

Prefer .NET APIs over shelling out

Use System.Diagnostics.Process and System.Net.NetworkInformation before reaching for ps, lsof, wmic, or netstat. Only shell out when no .NET API exists.

Isolate platform-specific code

When you must shell out, put ALL platform calls in a single static class PlatformHelper with:

A RuntimeInformation.IsOSPlatform() check

macOS and Windows branches

A private RunShell() helper for process execution

try/catch returning empty string on failure

This keeps platform-specific code to one place instead of scattered throughout.

Things that still need platform calls

Command-line args of another process: ps -o args= (macOS) / wmic (Windows)

Parent PID: ps -o ppid= (macOS) / wmic (Windows)

Port listener details: lsof -i (macOS) / netstat -ano (Windows)

Process property access on macOS

Process.StartTime, TotalProcessorTime, and WorkingSet64 may throw on macOS due to sandboxing or permissions. Always wrap in try/catch and show "N/A" on failure.
