Question

所以我有一些奇怪的事情发生了。我正在尝试让SendGrid v9在我的网络应用上工作。我通过一系列测试来运行它，包括创建一个控制台应用程序进行测试。它在控制台应用程序中运行良好，但挂在Web应用程序中。我显然错过了一些东西 - 可能与异步调用有关，但真的在寻找帮助：

我的控制台应用：

namespace Example
{
    using System;
    using System.Threading.Tasks;
    using Newtonsoft.Json;
    using SendGrid;
    using SendGrid.Helpers.Mail;
    using System.Collections.Generic;
    using System.Diagnostics;

    internal class Example
    {
        private static void Main()
        {
            Execute().Wait();
        }

        static async Task Execute()
        {
            var client = new SendGridClient("[MYKEY]");

            // Send a Single Email using the Mail Helper
            var from = new EmailAddress("my@email.com", "Example User");
            var subject = "Hello World from the SendGrid CSharp Library Helper!";
            var to = new EmailAddress("my@email.com", "Example User");
            var plainTextContent = "Hello, Email from the helper [SendSingleEmailAsync]!";
            var htmlContent = "<strong>Hello, Email from the helper! [SendSingleEmailAsync]</strong>";
            var msg = MailHelper.CreateSingleEmail(from, to, subject, plainTextContent, htmlContent);

            var response = await client.SendEmailAsync(msg);
            Debug.WriteLine(msg.Serialize());
            Debug.WriteLine(response.StatusCode);
            Debug.WriteLine(response.Headers);
        }
    }
}

我的网络应用：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Diagnostics;
using System.Threading.Tasks;
using Newtonsoft.Json;
using SendGrid;
using SendGrid.Helpers.Mail;


namespace WebAppTest
{
    public partial class WebForm1 : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            Execute().Wait();
        }

        public static async Task Execute()
        {
            var client = new SendGridClient("[MYKEY]");

            // Send a Single Email using the Mail Helper
            var from = new EmailAddress("my@email.com", "Example User");
            var subject = "Hello World from the SendGrid CSharp Library Helper!";
            var to = new EmailAddress("my@email.com", "Example User");
            var plainTextContent = "Hello, Email from the helper [SendSingleEmailAsync]!";
            var htmlContent = "<strong>Hello, Email from the helper! [SendSingleEmailAsync]</strong>";
            var msg = MailHelper.CreateSingleEmail(from, to, subject, plainTextContent, htmlContent);

            var response = await client.SendEmailAsync(msg); //It hangs on this call

            Debug.WriteLine(msg.Serialize());
            Debug.WriteLine(response.StatusCode);
            Debug.WriteLine(response.Headers);
        }
    }
}

这些是空白项目，在web.cofigs或app.configs

中没什么

我缺少什么。为什么Web应用程序无法正常运行，但控制台应用程序确实如此？

TIA

SendGrid仅挂在Web应用程序中（不在控制台应用程序中）
