Rule for unused rule suppressions

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.

Aucun fichier, test ou point d’entrée n’est indiqué. Commencez par déterminer comment Diagnostics.CodeAnalysis.SuppressMessageAttribute et les diagnostics des analyseurs sont gérés, puis définissez comment les suppressions obsolètes doivent être détectées et signalées pour les scénarios indiqués.
