HttpListener在發布模式下崩潰

Question

重現問題
1.創建一個Android應用程序
2.安裝Nito.AsyncEx.Context
3.添加以下代碼
4.設置釋放模式
5.部署代碼
6.啟動應用程序（並觀看它燃燒！它在我的10.1" Marshmallow...模擬器和Samsung Galaxy Note 10.1上都崩潰）

using Android.App;
using Android.Widget;
using Android.OS;
using System.Threading.Tasks;
using System.Net;
using System.Text;
using Nito.AsyncEx;

namespace App1
{
    [Activity(Label = "App1", MainLauncher = true, Icon = "@drawable/icon")]
    public class MainActivity : Activity
    {
        private readonly HttpListener listener = new HttpListener();

        protected override void OnCreate(Bundle bundle)
        {
            base.OnCreate(bundle);
            SetContentView(Resource.Layout.Main);
            var thread = new System.Threading.Thread(RunThread);
            thread.Start();
        }

        void RunThread()
        {
            AsyncContext.Run(() => Run()); //Exception in release mode
            //Task.Run(Run); //Silent exception in release mode
        }

        protected async Task Run()
        {
            listener.Prefixes.Add("http://localhost:8082/");
            listener.Start();
            while (true)
            {
                var context = await listener.GetContextAsync();
                var data = Encoding.UTF8.GetBytes("<html><body>Hello world</body></html>");
                context.Response.OutputStream.Write(data, 0, data.Length);
                context.Response.Close();
            }
        }
    }
}

我得到以下異常：

E/mono    (29964): Unhandled Exception:
E/mono    (29964): System.Net.Sockets.SocketException (0x80004005): mono-io-layer-error (10013)

要打開套接字，您的應用程序需要INTERNET權限。 AndroidManifest.xml下行添加到您的AndroidManifest.xml文件中：

<uses-permission android:name="android.permission.INTERNET" />
