[Bug] 1.5.0 "Get-IntuneWin32App -DisplayName $Appname" returns empty, counting is broken

[AlkHacNar]

I don't know if it's a PS5 issue or not, but "Get-IntuneWin32App -DisplayName $Appname" return empty, if there is only 1 Win32App in Intune or 1 App with the name. I fugured out that it can't count the apps, if there is only one App, maybe its because its an Object and not an array
($null -ne $Win32MobileApps -and $Win32MobileApps.Count -gt 0)
My workaround ist to change it to
($null -ne $Win32MobileApps -and @($Win32MobileApps).Count -gt 0)
and now it works fine. Like I said I don't know if it's only my System or no one had it testet with only 1 App in Intune or 1 App in the filter :D

You can call it a PS5 issue, but it's rather both a problem of Get-IntuneWin32App and a feature of PS7 :)

$Win32MobileApps = $Win32MobileApps | Where-Object { $_.displayName -like "*$($DisplayName)*" }

If there's only one match here, $Win32MobileApps becomes a single object of PSCustomObject type. And it doesn't have Count property. However PS7 has a builtin workaround, as per Copilot:

PowerShell 7 (PowerShell Core) adds convenience ETS members such as Count/Length as dynamic/script properties on many non-null scalar objects so they behave like single-item collections.

Therefore in PS7 $Win32MobileApps.Count returns 1 and the result gets processed correctly.

Your suggested fix would work just fine, but I'd rather handle it earlier in the code, at the variable declaration. Any of these seem to work:

[array]$Win32MobileApps = Invoke-MSGraphOperation -Get -APIVersion "Beta" -Resource "deviceAppManagement/mobileApps?`$filter=isof('microsoft.graph.win32LobApp')"

$Win32MobileApps = @(Invoke-MSGraphOperation -Get -APIVersion "Beta" -Resource "deviceAppManagement/mobileApps?`$filter=isof('microsoft.graph.win32LobApp')")
