Parallel ForEach not awaiting for HttpClient [duplicate]

In the code below (a fairly simple one just for demonstration), my finally clause gets executed when awaiting for the HttpClient to finish. So the output is something like:

Done

StatusCode: 200,...

When I was expecting it to be:

StatusCode: 200,...

Done

 class Program { private static HttpClient _httpClient = new HttpClient(); static async Task Main(string[] args) { var numbers = new List<int> {1}; try { await Task.Run(() => { Parallel.ForEach(numbers, async (number) => { await Do1(); }); }); } finally { Console.WriteLine("Done"); } Console.ReadKey(); } private static async Task Do1() { using (var result = await _httpClient.GetAsync("http://www.google.com")) { Console.WriteLine(result); } } private static async Task Do2() { for (int i = 0; i <= 10; i++) { Console.WriteLine("Doing" + await Multiply(i)); } } private static async Task<int> Multiply(int number) { return await Task.FromResult(number * number); } } 

If I replace my Main method to use the Do2 method then everything works as expected with the following output ("Done" gets printed at the very end):

So why is the HttpClient not working as I am expecting it to work? Something that I'd like to mention is that I would like to use the Parallel.ForEach instead of the Task.WhenAll function.
