类型为System.UnauthorizedAccessException＆＃39;的第一次机会异常。发生在System.Windows.ni.dll中

Question

我正在尝试为unity3d开发一个windows phone插件来显示admob广告。我是Windows Phone的新手。我按照here的步骤进行操作。我的windows phone类库类代码是：

using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using GoogleAds;

namespace UnityPluginForWindowsPhone
{
     /**
     * this class belongs to windows phone class library.
     **/
    public class TAdmob
    {
        private static string interstitialAdUnitId;
        private static InterstitialAd interstitialAd;

        public static void InitInterstitialAd(string adUnitId)
        {
            interstitialAdUnitId = adUnitId;
            interstitialAd = new InterstitialAd(adUnitId);           
        }

        public static void ShowInterstitialAd()
        {
            AdRequest adRequest = new AdRequest();
            interstitialAd.ReceivedAd += OnInterstitialAdRecieved;
            interstitialAd.LoadAd(adRequest);            
        }

        private static void OnInterstitialAdRecieved(object sender, AdEventArgs e)
        {
            interstitialAd.ShowAd();
        }

        public static string GetString()
        {
            return "Hello, Not a device";
        }
    }
}

我的windows类库类是：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace UnityPluginForWindowsPhone
{
    /**
     * this class belongs to windows class library which is used for the unity editor.
     **/
    public class TAdmob
    {

        public static void InitInterstitialAd(string adUnitId)
        {

        }

        public static void ShowInterstitialAd()
        {

        }
    }
}

我在日志中收到以下消息：

我试图找到无法使用Process Monitor访问的文件，并找到了这个。虽然无法找到它的含义。输出屏幕截图如下：

我无法弄清楚该怎么做。有谁知道如何解决这个问题？
