Steps to reproduce
There may be some rare cases where we would be using ParameterSetName instead of ParameterName, for example
$sb = {
function Test-PSReviewUnusedParameter {
<#
#>
[CmdletBinding()]
Param(
[Parameter(ParameterSetName = 'Foo')]
[switch]
$FooBar
)
try{
if ($PSCmdlet.ParameterSetName -eq 'Foo') {
# I am doing something
}
} catch {
throw
}
}
}
# Invoke-ScriptAnalyzer -ScriptDefinition [scriptblock]$sb
