Powershell debugging event -Action code block

Question

I have script watching file creation in a specific directory. I'm using Register-ObjectEvent after creating a System.IO.FileSystemWatcher,

It works great, but if I set a break point in the -Action code block the IDE generates a:

WARNING: Breakpoint Line breakpoint on 'D:\My Stuff\Desktop\scripts\fileWatcher.ps1:15' will not be hit

this message happens right after I drop a file into the directory I'm watching and I can see my Write-Host printing out my message right after the above 'warning'.

Is this normal?
I need to add more code and could really use the debugger.. What can\should I do, so I can debug this code block?

$fsw = [System.IO.FileSystemWatcher] $path

Register-ObjectEvent -InputObject $fsw –EventName Created -SourceIdentifier DDFileCreated -Action { 
    $name = $Event.SourceEventArgs.Name 
    $changeType = $Event.SourceEventArgs.ChangeType 
    $timeStamp = $Event.TimeGenerated 
    Write-Host "The file '$name' was $changeType at $timeStamp" -fore green 
    Out-File -FilePath $logFile -Append -InputObject "The file '$name' was $changeType at $timeStamp"
}

The real key is to have a loop running so the script never exits. Then debugging and breakpoints work.

E.g.

# At the end of the script.
while ($true) {
    Start-Sleep -Seconds 1
}
