Fake warning : $PSNativeCommandUseErrorActionPreference is assigned but never used

[CyberSinh]

Prerequisites

• I have written a descriptive issue title.
• I have searched all open and closed issues to ensure it has not already been reported.
• I have read the troubleshooting guide.
• I am sure this issue is with the extension itself and does not reproduce in a standalone PowerShell instance.
• I have verified that I am using the latest version of Visual Studio Code and the PowerShell extension.
• If this is a security issue, I have read the security issue reporting guidance.

Summary

If I have $PSNativeCommandUseErrorActionPreference = $true in a script, I get the following warning in the Visual Studio Code issue pane: $PSNativeCommandUseErrorActionPreference is assigned but never used.

It is correct to assigned PowerShell preference variables, without explicitly using them in script.

These alerts come from ScriptAnalyzer, so the issue's root would be there, could you reopen the issue there? There's nothing we can do about it here. Thanks!

Thanks @JustinGrote !
The issue should be fixed in the next PSScriptAnalyzer version:
PowerShell/PSScriptAnalyzer#1954

[JustinGrote]

Thanks @CyberSinh! I'll reopen this and it will be closed when that version gets integrated into the extension.

@CyberSinh can you confirm this is fixed in the latest pre-release, v2024.3.2-preview, which as PSScriptAnalyzer 1.22.0 (which is supposed to have that fix)? (Seems to be for me!)
