What is the correct path string I need for saving files to Azure Apps virtual applications and directories?

I'm using ASP.NET5 / MVC 6. I am trying to use a SQL logger on an app running in Azure Apps. Locally, I can access the directory I want, so I am pretty sure its not a syntax or system agnostic error. This is the part that fails while stepping through on remote debugging. Again, locally it runs and logs normally.

//Local path
private static readonly string _logFilePath = @"C\temp\DatabaseLog.sql";

//Azure App path
private static readonly string _logFilePath = @"\templog\DatabaseLog.sql";

public void Log(LogLevel logLevel, int eventId, object state, Exception exception, Func<object, Exception, string> formatter)
{
    var message = string.Format(
    "\n\n--{0}\n{1}",
    DateTime.Now,
    formatter(state, exception));//.Replace(", [", ",\n  ["));

    File.AppendAllText(_logFilePath, message); // <-- FAILS HERE
}

I have set \templog as a virtual directory in the Azure portal. See image:enter image description here

I have also created the folder in the project. See image:

Wouldn't you still have to map the virtual path to physical?

using either of 

private static readonly string _logFilePath = Server.MapPath(@"/templog/DatabaseLog.sql");

or 

private static readonly string _logFilePath = HostingEnvironment.MapPath(@"/templog/DatabaseLog.sql");

Have you tried writing to /App_Data?
Does the folder exist on azure?
Maybe there are permissions on the folder that need to be set?

The Azure App storage is mapped to d:\home so I would try to change:



    //Azure App path
    private static readonly string _logFilePath = @"\templog\DatabaseLog.sql";

to 



    //Azure App path
    private static readonly string _logFilePath = @"d:\site\templog\DatabaseLog.sql";
