Very weird issue. We store local cache for EF model in

Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData)

Been doing this for years.  We restarted the app this afternoon, and it suddenly crashed just on restart without any code changes.  In debugging I found that this code is now returning an empty string, so the path to save is invalid.

Why did this path suddenly cease to exist, and why on a restart without any actual code deployment?  Is there some documented change to Azure App Services that would explain how to properly retrieve AppData path?
