Can't find VM Templates using 'Get-Template' command

Hi all,

Apologies if this question has been asked before but haven't been able to find any information on it.

For some reason when I use the Get-Template command within PowerCLI I get no results even though I have templates on the datastore. Using a command such as Get-VM works as expected but for some reason the Get-Template command just won't find anything. Is there anything glaringly obvious that I may have missed out perhaps in the configuration of my virtual environment?

The environment consists of one Datacenter with one ESXi 5.1 host and multiple VMs residing on it. I also have a vCenter virtual appliance to manage the host.

Thanks,

Matt
