描述

Area - Rules Issue-Enhancement Up-for-Grabs

Currently there are quiet some reason to suppress a certain rule as e.g.:

  • Not be able to (easily) work around an issue
  • False positives

There are also a few reasons a rule suppression might get obsolete, e.g.:

  • The script issue gets resolved
    e.g. all the Write-Host cmdlet are been replaced which a different cmdlet
  • The script issue doesn't anymore apply
    e.g. a PSReviewUnusedParameter parameter get completely depreciated or a variable gets (also) used in scope
  • PSScriptAnalyzer update
    e.g. a false positive might get fixed in a newer version of PSScriptAnalyzer

In all the situations I would like to be warned that there is a Diagnostics.CodeAnalysis.SuppressMessageAttribute that is no longer required.

This will avoid a scenario were:

  • Someone resolves an analyzer issue (e.g. PSAvoidUsingWriteHost ) in a particular script but forgets to remove the SuppressMessageAttribute from the annotations
  • Someone else updates the same script but unseen reintroduces the analyzer issue (e.g. Write-Host ) again.
