timeout policy not working

[janeliu567]

I'm trying out the timeout policy with polly. I expect an exception to be thrown after 1 sec passed because that is the timeout upper limit I set up. But currently, no exception will be thrown and the method LongOperation() returns normally after around 5 secs.

Why does the timeout policy not work in this case?

static void Main(string[] args)
{
    Stopwatch stopwatch = new Stopwatch();
    stopwatch.Start();

    timeoutPolicy().GetAwaiter().GetResult();

    stopwatch.Stop();
    Console.WriteLine("Time elapsed: {0}", stopwatch.Elapsed);
    Console.ReadKey();
}

static async Task timeoutPolicy()
{
    AsyncTimeoutPolicy<HttpResponseMessage> timeoutPolicy = Policy.TimeoutAsync<HttpResponseMessage>(1); // setup the timeout limit to be 1 sec

    HttpResponseMessage response = await timeoutPolicy.ExecuteAsync((ct) => LongOperation(), CancellationToken.None);

    Console.WriteLine(response);



}

static Task<HttpResponseMessage> LongOperation()
{
    return Task<HttpResponseMessage>.Factory.StartNew(() =>
    {
        Thread.Sleep(5000); // Sleep 5 seconds
        return new HttpResponseMessage()
        {
            StatusCode = HttpStatusCode.BadRequest
        };

    });
}
