[DSCPlatformIssue]New-ScheduledTaskTrigger not compatible with PowerShell 4 and 5

[cveld]

I am getting the following exception when trying out the cScheduleTask resource: `Method "NewTriggerByDaily" not found

• CategoryInfo : ObjectNotFound: (PS_ScheduledTask:) [], CimException
• FullyQualifiedErrorId : HRESULT 0x80041002,New-ScheduledTaskTrigger
• PSComputerName : localhost`

This is on a Windows 7 laptop with PowerShell 4 and on a Windows 10 laptop with PowerShell 5 installed.

I have found the following forum discussion that seems to contain the answer: http://powershell.org/wp/forums/topic/method-newtriggerbyonce-not-found-taskscheduler/

It looks like New-ScheduledTaskTrigger -Daily -At '11AM' constructions need to be replaced by New-JobTrigger -Daily -At 11AM. I have tested these two expressions on my test devices and both respond as expected, i.e. the first generates the exception New-ScheduledTaskTrigger : Method "NewTriggerByDaily" not found whereas the second replies with a JobTrigger object.

Thank you for reporting.

I knew there are Bug with New-ScheduledTaskTrigger on WMF5, includes Windows 10, with -Daily, Once, Weekly and others. You can find this bug in UserVoice https://windowsserver.uservoice.com/forums/301869-powershell/suggestions/11190663-bug-scheduledtasks-module-broken-in-1511

Unfortunately your proposal, and also link to the powershell.org, New-JobTrigger -Daily -At 11AM describe not a ScheduledTask but about ScheduledJob. As you can see this resource is about ScheduledTask not a ScheduledJob. Because they are completely interface incompatible each other. ScheduledJob Type couldn't be used for ScheduledTask.

PS C:\Users\> $trigger = New-JobTrigger -Daily -At 11AM | gm
PS C:\Users\> $action = New-ScheduledTaskAction -Execute powershell.exe
PS C:\Users\> New-ScheduledTask -Action $action -Trigger $trigger
New-ScheduledTask : Cannot process argument transformation on parameter 'Trigger'. Cannot convert the "bool
Equals(System.Object obj)" value of type "Microsoft.PowerShell.Commands.MemberDefinition" to type

Future Plan

So what the option? Yes I have idea with, however this idea is completely through away PowerShell ScheduledTask Module and shift all logic to C#. I already implement for C#, works perfect in production, but not yet ported to PowerShell.

Question

Do you experience same issue on Windows Server 2012 R2 WMF4 and WMF5 RTM? I have tested with Windows Server 2012 R2 + WMF4 (w/Nov update) without any issue but not yet for other environment.

I just want to know whether this issue is limited or give up with PowerShell ScheduledTask Module, sigh.... :(

I quickly tested on a 2012R2 server with the following $PSVersionTable and I don't get the exception:

Thank you cveld,

It might be better through PowerShell away and use C# Implementation.

I will do it, please wait a moment.
