I followed the steps shown in the video.
Created a vnet –> created a VM.
While creating a VM under networking Tab the virtual network which I created for this lab is not been displayed instead some other default name is popping with default IP details.
Make sure you have the same region chosen for the VM as you created the VNet in, e.g. Australia Southeast. Because a virtual network is a physical implementation under the covers, the VM has to be in the same physical region as well.
Let me know if that works.
