Question

我已经安装了Visual Studio 2015 Community Edition。我已经安装了Xamarin试用版。我在Xamarin iOS Universal项目中使用以下示例代码AppDelegate.cs。

当我使用Debug.WriteLine将消息写入Visual Studio输出窗口时，我似乎将消息重复了3次。

当我使用Console.WriteLine我的信息没有被重复时，似乎偶尔会出现某种竞争条件导致我的一些消息突破两条不同的行。

示例代码：

using System;
using System.Diagnostics;
using Foundation;
using UIKit;

namespace LandingDay.Example1.Xamarin.iOSUniversal
{
    // The UIApplicationDelegate for the application. This class is responsible for launching the 
    // User Interface of the application, as well as listening (and optionally responding) to 
    // application events from iOS.
    [Register("AppDelegate")]
    public class AppDelegate : UIApplicationDelegate
    {
        public override UIWindow Window { get; set; }

        // This method is invoked when the application has loaded and is ready to run. In this 
        // method you should instantiate the window, load the UI into it and then make the window
        // visible.
        //
        // You have 17 seconds to return from this method, or iOS will terminate your application.
        //
        public override bool FinishedLaunching(UIApplication app, NSDictionary options)
        {
            Debug.WriteLine("This is a test. ABCDEFGHIJKLMNOPQRSTUVWXYZ abcdefghijklmnopqrstuvwxyz");

            for (int i = 0; i < 20; i++)
            {
                Console.WriteLine("This is a test. ABCDEFGHIJKLMNOPQRSTUVWXYZ abcdefghijklmnopqrstuvwxyz");
            }

            return true;
        }
    }
}

必需的行为：

能够像在Xamarin iOS Universal项目中的示例代码中那样写入Visual Studio Output窗口，而不会重复3次消息或间歇性地断开多行消息。
