# The application_type attribute is now case senstive. If the resource has been previously created with provider v1.x and the 
# application_type was not lower case, then changing it to suit the v2 provider will result in the resource being destroyed 
# and re-created since there is no way to update this value in place 
# (see https://github.com/terraform-providers/terraform-provider-azurerm/issues/5902). 
  
# To prevent this, add a lifecycle customisation and specify application_type as an attribute to ignore. Any attribute specified
# in the ignore_changes array will not be considered when creating a plan for an update, but they will still be part of creating
# a new resource.
