How could be layout for a call stack look?

My question: How could be the layout for a CALL STACK look?
referrence:
public f1();
private async Task ScrapeHtmlPage(object caller, EventArgs e)  {  WebClient wc = new WebClient();  var result = await wc.DownloadStringTaskAsync("http://www.microsoft.com");  // Do something with the result } private f2(); That's all you have to write — the .NET Framework will automatically handle unwinding the call stack while waiting for the download to complete, as well as automatically restoring the call stack after the download is done.
Is it so the "call stack" looks like this?
1002::Private_f1
1003::Private_async_Task_ScrapeHtmlPage_caller_e
1004::Private_f2
