WCF ConcurrencyMode多个不起作用

我阅读了很多关于wcf并发和实例上下文模式的帖子,我也阅读了CodeProject文章,但仍无法使其工作。

这是我的客户端代码(如果你问我为什么使用实例上下文,那是因为我最终将测试回调,但我还没有,只是尝试多次同时做一个简单的请求/响应)

    public void Run()
    {
        InstanceContext context = new InstanceContext(this);
        MyServiceReference.MyService service = new MyServiceReference.MyService(context);

        for (int i = 0; i < 10; i++)
        {
            int j = i;
            Thread t = new Thread(() => myFun((j + 1), service));
            t.Start();
        }
        countdownEvent.Wait();

        Console.ReadLine();
        service.Close();
    }

    private void myFun(int threadNo, MyServiceReference.MyServiceClient service)
    {
        Console.WriteLine(service.GetData1(threadNo));
        countdownEvent.Signal();
    }

这是服务代码:

[ServiceContract(CallbackContract = typeof(IMyServiceCallback))]
public interface IMyService
{
    [OperationContract]
    string GetData1(int value);
}

public interface IMyServiceCallback
{
    [OperationContract]
    string GetData2(int value);
}

[ServiceBehavior(ConcurrencyMode = ConcurrencyMode.Multiple, UseSynchronizationContext=false)]
public class MyService : IMyService
{

    public string GetData1(int value)
    {
        reponse = DateTime.Now.ToString();

        Thread.Sleep(5000);

        return "Request: " + value + ", Thread id: " + Thread.CurrentThread.ManagedThreadId + ", response: " + reponse;
    }

这是输出:

Request: 1, Thread id: 9, response: 2015-08-14 11:39:42
Request: 2, Thread id: 10, response: 2015-08-14 11:39:47
Request: 3, Thread id: 8, response: 2015-08-14 11:39:52
Request: 4, Thread id: 9, response: 2015-08-14 11:39:57
Request: 5, Thread id: 10, response: 2015-08-14 11:40:02
Request: 6, Thread id: 9, response: 2015-08-14 11:40:07
Request: 7, Thread id: 10, response: 2015-08-14 11:40:12
Request: 8, Thread id: 9, response: 2015-08-14 11:40:17
Request: 9, Thread id: 10, response: 2015-08-14 11:40:22
Request: 10, Thread id: 9, response: 2015-08-14 11:40:27

我希望将ConcurrencyMode设置为多个会使请求通过使用多个线程同时运行,但即使我看到使用3个线程,操作仍然按顺序执行(每个响应之间5秒),我缺少什么?< / p>

我看到的每个例子都使用了void返回和IsOneWay = True的操作,这就是为什么它对我不起作用? 但是,我在客户端上为每个请求使用不同的线程,因此所有请求都应该同时完成,即使每个线程都在等待自己的响应。

我正在使用WCF服务主机和NetTcpBinding运行调试,可以在调试中运行影响并发吗?

尝试将您的服务标记为InstanceContextMode.PerCall:
