In this article, we will learn how can we delete the resources associated to a resource group.
Sometimes, we have lot of resources connected to a resource manager group. If you need to delete a resource group then you need to delete all the resources first.
So deleting all the resources from management portal is time consuming as we need to delete it one by one.
we can delete all the resources in a single shot with this simple powershell command -

Remove-AzureRmResourceGroup -Name ResourceGroupname

You need to put your resource group name with -Name parameters and this cmdlet will delete all the resources associated with this Resource group.
