Azure ASEs ARM Templates and resourceGroup.location() function

In a recent post I wrote about Azure App Service Environments (ASEs) and AD Integration. If you look at the Azure Quickstart template for a Web App in an ASE, you will notice that the location is passed in as a parameter instead of using the resourcegoup.location() function. This is because there is a known issue where the backend infrastructure for ASEs is not correctly handling the location string returned by this function call. This is mentioned in the following stackoverflow article http://stackoverflow.com/questions/42490728/azure-arm-cant-create-hostingenvironments-location-has-an-invalid-value.
