说明：无论是何种方式异步访问（实现非阻塞），一般都需额外开启线程进行。

一、委托访问

using System;
    using System.ServiceModel;
    using System.Threading;
    using System.Windows;
    
    namespace singleProxyServer_WpfClient
    {
    
        public delegate ProxyServerService.CompositeType deletegate_callback(ProxyServerService.CompositeType type);
    
        /// <summary>
        /// MainWindow.xaml 的交互逻辑
        /// </summary>
        public partial class MainWindow : Window
        {
            static ProxyServerService.SingleServiceClient client = new ProxyServerService.SingleServiceClient("NetTcpBinding_ISingleService", "net.tcp://localhost/SingleService");
    
            ProxyServerService.CompositeType compositeType ;
    
            deletegate_callback delegate_call = new deletegate_callback(client.GetDataUsingDataContract);
    
            public MainWindow()
            {
                InitializeComponent();
            }
    
            private void Button_Click(object sender, RoutedEventArgs e)
            {
                if (client == null || client.State != CommunicationState.Opened)
                    client = new ProxyServerService.SingleServiceClient("NetTcpBinding_ISingleService", "net.tcp://localhost/SingleService");
    
                compositeType = new ProxyServerService.CompositeType();
                try
                {
                    IAsyncResult asResult2 = delegate_call.BeginInvoke(compositeType, new AsyncCallback(onCallBack) , null);
                }
                catch(Exception ex)
                {
                    client.Abort();
                }
                finally
                {
                    //client.Close();
                }
            }
    
            private void onCallBack(IAsyncResult result)
            {
                deletegate_callback dlgt = (deletegate_callback)result.AsyncState;  
                ProxyServerService.CompositeType type = delegate_call.EndInvoke(result);
                MessageBox.Show(type.StringValue+";"+ Thread.CurrentThread.ManagedThreadId);
    
            }
    
            private void Button_Click_1(object sender, RoutedEventArgs e)
            {
                MessageBox.Show("helloWorld");
            }      
    
        }
    }

二、线程访问

using System;
    using System.ServiceModel;
    using System.Threading;
    using System.Threading.Tasks;
    using System.Windows;
    
    namespace singleProxyServer_WpfClient
    {
    
        /// <summary>
        /// MainWindow.xaml 的交互逻辑
        /// </summary>
        public partial class MainWindow : Window
        {
            ProxyServerService.SingleServiceClient client;
    
            ProxyServerService.CompositeType compositeType ;
    
            public MainWindow()
            {
                InitializeComponent();
            }
    
            private void Button_Click(object sender, RoutedEventArgs e)
            {
                if (client == null || client.State != CommunicationState.Opened)
                    client = new ProxyServerService.SingleServiceClient("NetTcpBinding_ISingleService", "net.tcp://localhost/SingleService");
    
                compositeType = new ProxyServerService.CompositeType();
                try
                {
                    //MessageBox.Show(Thread.CurrentThread.ManagedThreadId.ToString());
    
    
                    Task t = Task.Factory.StartNew(() =>
                    {
                        ProxyServerService.CompositeType cp = client.GetDataUsingDataContract(compositeType);
                        MessageBox.Show(cp.StringValue + ";" + Thread.CurrentThread.ManagedThreadId);
                    });
    
                    Task t2 = Task.Factory.StartNew(() =>
                    {
                        ProxyServerService.CompositeType cp = client.GetDataUsingDataContract(compositeType);
                        MessageBox.Show(cp.StringValue + ";" + Thread.CurrentThread.ManagedThreadId);
                    });
                }
                catch(Exception ex)
                {
                    client.Abort();
                }
                finally
                {
                    //client.Close();
                }
            }
    
            private void Button_Click_1(object sender, RoutedEventArgs e)
            {
                MessageBox.Show("helloWorld");
            }      
    
        }
    }
