我对Xamarin和移动开发很新，但有C＃的经验。 以下是我尝试从网上获取一些代码并将其调整为Xamarin。 拨打电话时，代码在例外时失败。 实际上，我无法在CallReceiver / PhonecallReceiver类中访问断点。 我正在运行VS2017社区，API23，手机。 我缺少什么？

MainActivity：

using Android.Widget;

using System.Collections.Generic;
using Java.Util;
using Javax.Security.Auth;

    public override void OnReceive(Context context, Intent intent)
    {

        }
        else
        {
            String stateStr = intent.Extras.GetString(TelephonyManager.ExtraState);
            String number = intent.Extras.GetString(TelephonyManager.ExtraIncomingNumber);
            CallState state = CallState.Idle;

            if (stateStr.Equals(TelephonyManager.ExtraStateIdle))
