PowerShell : Retry logic in Scripts

One of my projects required me to copy a CSV file (important step) to a VM running on Server 2012 R2. I’ve found this excellent tip by Ravi on using Copy-VMfile cmdlets in Server 2012 R2 Hyper-V . To use this cmdlet, I had to enable " Guest Service Interface " component in the Integration Services (below is what documentation says about the service). This new component in the Integration Services allows copying files to a running VM without any network connection (How cool is that?). The tip mentioned earlier talks about how to enable the component using Enable-VMIntegrationService, but there is a delay between enabling the component and successfully using the Copy-VMfile cmdlet.  So how do I go about making sure that the service is running before the cmdlet is issued, or keep retrying the cmdlet until it succeeds ?
