Функция httptrigger httptrigger Избегайте ответа ⇐ C#

[Anonymous]

В Visual Studio я создал новый проект Function Azure с функцией httptrigger.
Это код для функции: < /p>
public class DoSomething
{
private readonly ILogger _logger;

public DoSomething(ILogger logger)
{
_logger = logger;
}

[Function("DoSomething")]
public async Task Run([HttpTrigger(AuthorizationLevel.Function, "get", "post")] HttpRequest req)
{
try
{
_logger.LogInformation("C# HTTP trigger function processed a request.");
for (int i = 0; i
Функция вызывается с помощью этого приложения консоли: < /p>
Task.Run(async () =>
{
using var client = new HttpClient();
var res = await client.PostAsync("http://localhost:7129/api/DoSomething", null);
});

//Do other stuff
await Task.Delay(4000);
< /code>
Намеренно мое консольное приложение закрывается до того, как функция завершит свою работу.
В журнале функции я получаю эти сообщения: < /p>

Почему мой код функции бросает исключение? Исключение Я ожидал этого во время выполнения кода функции.
Есть ли способ избежать исключения, не ожидая ответа функции от вызывающего абонента ?
Спасибо
