"PowerCLI Tip: Tagging VMs Requires Object, Not String"

    I've seen a lot of confusion around tagging VMs via PowerCLI-especially when using New-TagAssignment.

    If you pass a VM name string directly like -Entity "vmname", it will fail because -Entity expects a VM object, not a string.

    You have two clean options:

    1- Pipe the VM object directly:

    Get-VM -Name "vmname" | New-TagAssignment -Tag $tag

    2- Assign the VM object to a variable first:

    $vm = Get-VM -Name "vmname"
New-TagAssignment -Tag $tag -Entity $vm

    Both approaches ensure you're passing the correct object type to New-TagAssignment. Hope this clears things up!
