async call without wait

static void Main(string[] args)
{
  try
  {
    // output "hello world" as method returns early
    Console.WriteLine(GetStringData());
  }
  catch
  {
    // Exception is NOT caught here
  }
  Console.ReadLine();
}

public static string GetStringData()
{
  MyAsyncMethod().ContinueWith(OnMyAsyncMethodFailed, TaskContinuationOptions.OnlyOnFaulted);
  return "hello world";
}

public static async Task MyAsyncMethod()
{
  await Task.Run(() => { throw new Exception("thrown on background thread"); });
}

public static void OnMyAsyncMethodFailed(Task task)
{
  Exception ex = task.Exception;
  // Deal with exceptions here however you want
}
