当我想在mscorlib.ni.dll中使用nuget SocketEx：FileNotFoundException时

Question

我想使用nuGet库中的Socketex.tcpclient。 我这样添加：

当我想在应用程序中使用它时

using Microsoft.Phone.Controls;
using System;
using System.Windows;
using System.Windows.Navigation;
using SocketEx;
using System.Threading;
namespace HomeSecurityClient {
    public partial class MainPage : PhoneApplicationPage {
        private string localIP, globalIP, port;
        private Thread sendThread;
        public MainPage() {
            InitializeComponent();
        }
        protected override void OnNavigatedTo(NavigationEventArgs e) {
            base.OnNavigatedTo(e);
            String args = null;
            NavigationContext.QueryString.TryGetValue("ms_nfp_launchargs", out args);
            if (args != null) {
                MessageBox.Show(args);
                string[] splittedArgs = args.Split(' ');
                globalIP = splittedArgs[0];
                port = splittedArgs[1];
                localIP = splittedArgs[2];
                makeSwitch();
                sendThread = new Thread(new ThreadStart(makeSwitch));
                sendThread.Start();
            }
        }

        private void makeSwitch() {         
            TcpClient client = new TcpClient(localIP, Int32.Parse(port));//THIS CAUSES THIS MESSAGE
      //      client.Connect(localIP, Int32.Parse(port));
        }
    }
}

在我接受消息框并调用方法makeSwitch后，我得到：

'TaskHost.exe' (CoreCLR: Silverlight AppDomain): Loaded 'C:\Data\Programs\{39989B95-A54A-4810-B4EE-35B33265A680}\Install\socketex.tcpclient.DLL'. Cannot find or open the PDB file.

如何解决？
