ScheduledTask: ScheduleType Parameter mismatch for `AtLogOn`

[jordanbreen28]

Problem description

Accepted values for the ScheduleType parameter are Once, Daily, Weekly, AtStartup, AtLogOn and OnEvent. However, when applying the below configuration, and supplying any variation of AtLogOn, AtLogon, Atlogon or atlogon, the value is always set and returned as AtLogon. I would argue this is a bug, as the value saved should match one of the "acceptable" values defined in the schema. So the value saved against the resource should be AtLogon and the accepted value here https://github.com/dsccommunity/ComputerManagementDsc/blob/d05adb09e753e0deebd7687b83dbba6584dfc6c7/source/DSCResources/DSC_ScheduledTask/DSC_ScheduledTask.schema.mof#L10, updated to AtLogon.

DSC configuration

Configuration ScheduledTask_CreateScheduledTasksAtLogon_Config
{
    Import-DscResource -ModuleName ComputerManagementDsc

     Node 'localhost'
    {
        ScheduledTask ScheduledTaskLogonAdd
        {
            TaskName           = 'SessionPopup'
            actionexecutable   = 'powershell'
            actionarguments    = '-File "C:\Program Files\windowspowershell\scripts\Epic.Wss.sessionpopup\Epic.Wss.SessionPopup.ps1"'
            ScheduleType       = 'AtLogOn'
        }
    }
}

ScheduledTask_CreateScheduledTasksAtLogon_Config

Suggested solution

Update the allowed values at https://github.com/dsccommunity/ComputerManagementDsc/blob/d05adb09e753e0deebd7687b83dbba6584dfc6c7/source/DSCResources/DSC_ScheduledTask/DSC_ScheduledTask.schema.mof#L10 to accept AtLogon over AtLogOn.
