From @BenRamachandran via Twitter

"Hello there. I'm Ben from Goprego. My company subscribed to Azure where I'm trying to setting a static IP. However, I can't continue as the powershelgl can't recognise my virtual network when I press below comment to view the IP availabilities.

I need to get AzureVNetConfig according to the forum

however i can't retire it...

i used the command of Get-AzureVNetConfig -ExportToFile "C:\Users\CS-101\Documents\vnet.xml""
