{
    [xml]$thisCsDefXml = Get-Content $thisCsDefFile
$root = $thisCsDefXml.get_DocumentElement();

If (!$root.WebRole.vmsize)
{ Write-Host "No webrole found in $($root.name) "
}
else
    {
    $root.WebRole.vmsize = $newvmsize
$thisCsDefXml.Save($thisCsDefFile)
Write-host "Webrole size of $($root.name) changed to $($root.WebRole.vmsize)"
    }
