PSScriptAnalyzer doesn't seem to be using the SuppressMessageAttribute ctor fields as intended.

So here is an example of how PSScriptAnalyzer is using this attribute to target a parameter:

[System.Diagnostics.CodeAnalysis.SuppressMessageAttribute("PSProvideDefaultParameterValue", "b")]
[System.Diagnostics.CodeAnalysis.SuppressMessageAttribute("PSProvideDefaultParameterValue", "a")]
Param([string]$a, [int]$b)

But the intent of the first two parameters of the SuppressMessageAttribute constructor are to uniquely identify the suppressed rule, and to apply to a parameter would use the MessageId property e.g.:

[SuppressMessage("Microsoft.Performance", "CA1801:ReviewUnusedParameters", MessageId = "isChecked")]
[SuppressMessage("Microsoft.Performance", "CA1804:RemoveUnusedLocals", MessageId = "fileIdentifier")]
static void FileNode(string name, bool isChecked)

So I would expect that every PowerShell suppression of a built-in rule would start like this:

[Diagnostics.CodeAnalysis.SuppressMessageAttribute("Microsoft.PowerShell", "PSAvoidUsingCmdletAliases")]

This identifies the rule as a built-in rule. I could imagine custom rules would use their module/assembly name in the first field (category).

Suppression of a parameter should look like:

[Diagnostics.CodeAnalysis.SuppressMessageAttribute("Microsoft.PowerShell", "PSProvideDefaultParameterValue", MessageId="b")]
[Diagnostics.CodeAnalysis.SuppressMessageAttribute("Microsoft.PowerShell", "PSProvideDefaultParameterValue", MessageId="a")]
Param([string]$a, [int]$b)

Note that MessageId is the field that is supposed to be used if Scope/Target aren't sufficiently precise.

Commencez par localiser le code de PSScriptAnalyzer qui interprète SuppressMessageAttribute et suivre la manière dont ses arguments de constructeur et MessageId sont traités. Comparez les suppressions ciblant des paramètres avec la sémantique de l’attribut présentée dans l’issue ; le travail est considéré comme terminé lorsque les suppressions de règles intégrées utilisent les champs de catégorie et de règle, tandis que les cibles spécifiques aux paramètres utilisent MessageId.
