我在运行这个正在运行的应用程序时遇到错误！

{＆＃34;＆＃39;在类型＆＃39; WpfApplication1.MainWindow＆＃39;上调用构造函数匹配指定的绑定约束引发异常。＆＃39;行号＆＃39; 3＆＃39;和行位置＆＃39; 9＆＃39;。＆＃34;}

MainWindow构造函数：

public partial class MainWindow : Window
{
    SkypeLink skype = new SkypeLink();
    VoiceSynth voiceSynth = new VoiceSynth();
    VoiceRecognizer voiceRecognizer = new VoiceRecognizer();
    GPS gps = new GPS();
    DispatcherTimer contactsTimer = new DispatcherTimer();
    DispatcherTimer callTimer = new DispatcherTimer();
}
