Unable to delete Azure Virtual Network Gateway using Resource Manager - powershell

Question

I created an Azure Virtual Network using PowerShell:
$gwpip= New-AzureRmPublicIpAddress -Name TestVNet -ResourceGroupName TestRg -Location 'West Europe' -AllocationMethod Dynamic -DomainNameLabel TestVNet
$vnet = Get-AzureRmVirtualNetwork -Name TestVNet -ResourceGroupName TestRg
$subnet = Get-AzureRmVirtualNetworkSubnetConfig -Name 'GatewaySubnet' -VirtualNetwork $vnet
$gwipconfig = New-AzureRmVirtualNetworkGatewayIpConfig -Name TestVNet -SubnetId $subnet.Id -PublicIpAddressId $gwpip.Id
New-AzureRmVirtualNetworkGateway -Name TestVNet -ResourceGroupName TestRg -Location 'West Europe' -IpConfigurations $gwipconfig -GatewayType Vpn -VpnType RouteBased
This worked perfectly. I now want to delete this Virtual Network Gateway, but that doesn't seem to work. When I use the delete button in the Portal I get a message: "Successfully saved configuration changes to virtual network TestVNet"
When I use PowerShell it doesn't return anything, unless I use the -debug and -verbose switch.
Remove-AzureRmVirtualNetworkGateway -Name TestVNet -ResourceGroupName TestRg -Force -Verbose -Debug
The final HTTP response says:
Body:
{
"status": "Failed",
"error": {
"code": "InternalServerError",
"message": "An error occured.",
"details": []
}
When I check the audit logs in the Portal I see two Microsoft.Network/virtualNetworkGateways/delete events, both Informational. The first has status Started, the second Accepted. After that, nothing happens anymore. Using the Portal or PowerShell doesn't make a difference in the audit log.
Any suggestions on how I can remove the gateway?

Answer 1

Whilst this isn't the nicest way, I've found you can do the following
Remove Azure PowerShell 1.0 or use a machine with Azure PowerShell 0.9 installed
Connect up to your Tenant
Import-Module Azure
Add-AzureAccount
Switch-AzureMode -Name AzureResourceManager
Then from here force remove the Resource Group housing everything - Be warned, this will delete everything in the resource group
Remove-AzureResourceGroup -Name TestRg -Force -Verbose
After a while, everything will be gone. Whilst it doesn't remove just the VNet, or the Gateway, or just the Connection, it will give you a blank test bed again.
Hope this helps.
