Android NoSuchMethodError being thrown on ArrayAdapter Constructor

I'm attempting to extend the generic ArrayAdapter in order to customize a ListView and am getting an NoSuchMethodError being thrown when I hit the TpAdapter (my extended Adapter) constructor

Here is the exteded ArrayAdapter TpAdapter

    private class TpAdapter : ArrayAdapter<MobileTalkingPoint>
    {
        private MobileTalkingPoint[] items;
        private Context outer_context;

        public TpAdapter(Context context, int textViewResourceId, MobileTalkingPoint[] items)
            : base(context, textViewResourceId, items)
        {
            this.items = items;
            this.outer_context = context;
        }

        public override View GetView(int position, View convertView, ViewGroup parent)
        {
            View v = convertView;

            if (v == null)
            {
                LayoutInflater vi = (LayoutInflater)outer_context.GetSystemService(Context.LayoutInflaterService);
                v = vi.Inflate(Resource.Layout.ItemTalkingPoint, null);
            }
            MobileTalkingPoint tp = items[position];
            if (tp != null)
            {
                TextView tpDate = v.FindViewById<TextView>(Resource.Id.tpDate);
                TextView tpTitle = v.FindViewById<TextView>(Resource.Id.tpTitle);
                TextView tpType = v.FindViewById<TextView>(Resource.Id.tpType);
                TextView tpBody = v.FindViewById<TextView>(Resource.Id.tpBody);

                tpDate.Text = String.Format("{0:MM/dd/yy}", tp.TPDate);
                tpTitle.Text = tp.Title;
                tpType.Text = tp.Type;
                tpBody.Text = tp.Descr;
            }

            return v;
        }
    }

I am instantiating them as follows in the activity:

        MobileTalkingPoint[] weaknesses = talkingPoints;

        TpAdapter adapStrength = new TpAdapter(this, Resource.Layout.ItemTalkingPoint, strengths);

And the stacktrace for the exception is as follows

I'm not sure if this is a bug in Mono For Android or not (seems like it might be, though), but if you modify your adapter to take in an IList instead of an array, the problem goes away:

private class TpAdapter : ArrayAdapter<MobileTalkingPoint>
{
    public TpAdapter(Context context, int textViewResourceId, IList<MobileTalkingPoint> items)
        : base(context, textViewResourceId, items)
    {
    }
}

You can still call it using an array, so that doesn't need to be modified:

MobileTalkingPoint[] points = { };
TpAdapter adapStrength = new TpAdapter(this, Resource.Layout.ItemTalkingPoint, points);
