Hi @Anthony B ,

welcome to the Microsoft Q&A Platform!
Remove App Service Link Association:

Go to Virtual Network > Subnets in the Azure portal.

Locate the subnet, check for Service Association Links, and remove any links.

Delete Dependent Resources:

Ensure no resources (e.g., App Services, VMs, SQL databases) are using the subnet.

Delete any remaining associated resources.

Retry Deletion:

Once dependencies are cleared, attempt to delete the subnet

Use Azure CLI for Forced Disassociation (if needed):

az network vnet subnet update \ --resource-group <ResourceGroupName> \ --vnet-name <VNetName> \ --name <SubnetName> \ --remove serviceAssociationLinks

refer to Delete a Subnet in Azure.

Thank you for the response, but unfortunately I don't have any Service Association Links visible on the platform, and even after execute the power shell cmd the error is still there when I try to delete my subnet...

Hi @Anthony B ,
Thankyou for your response.
It looks like you're facing an issue where a subnet can't be deleted due to an association with an App Service Link,
Check for Other Dependencies: Ensure no resources (App Services, VMs) are using the subnet.

Use Azure CLI/PowerShell: Run the command to remove Service Association Links.

az network vnet subnet update \ --resource-group <ResourceGroupName> \ --vnet-name <VNetName> \ --name <SubnetName> \ --remove serviceAssociationLinks

Check App Service Linking: Go to App Service > Networking > VNet Integration and ensure no active connections to the subnet.

Force Disassociation (PowerShell):

az network vnet subnet update ` --resource-group <ResourceGroupName> ` --vnet-name <VNetName> ` --name <SubnetName> ` --remove serviceAssociationLinks

Remove Dependencies Manually: Delete any resources still associated with the subnet.
