我正在设计一个WPF应用程序使用的WCF服务。该服务将由50个客户端使用，并托管在多核服务器上。这就是为什么我希望它是多线程的

我是这样宣布的：

[ServiceContract(
    SessionMode = SessionMode.Required,
    Namespace = Constants.NameSpace,
    CallbackContract = typeof (ISaphirServiceCallback))]
public interface ISaphirService


[ServiceBehavior(ConcurrencyMode = ConcurrencyMode.Multiple, 
                InstanceContextMode=InstanceContextMode.PerSession)]
public partial class SaphirService : ISaphirService

以及服务器端配置：

问题是，每个请求都在同一个线程上处理。我在网上查了很多，但对我来说一切都很好

你们知道吗

谢谢

如果希望服务在来自同一客户端的调用之间保持某些状态，那么值得一提的是

InstanceContextMode=InstanceContextMode.PerSession

。否则，您可以在打开

服务主机时使用InstanceContextMode=InstanceContextMode.PerCall
WCF捕获当前同步上下文
，并将其用于所有调用。WPF的同步上下文将每个调用发布到调度程序队列，该队列最终在UI线程上执行
您有两个选择：

在没有同步上下文的其他线程上启动服务。这样做的另一个优点是不会阻塞等待加载服务的UI线程。例如，您可以使用：
Task.Run(() => serviceHost.Open());


指定服务不应使用同步上下文：
[ServiceBehavior(UseSynchronizationContext = false)]



请注意，如果您在服务方法中修改UI对象，您可能需要自己将它们分派回UI线程。
您是如何检查的？如果50个客户端执行该服务，而您在其中设置了睡眠，那么它们是否会一个接一个地等待处理？有多少个请求，在什么时间段内，以及持续多长时间？我与两个客户端进行了检查。首先，可以清楚地看到，来自客户端2的请求1正在等待来自客户端1的第一个请求，还有一些控制台。写入（ManagedThreadId）到目前为止，来自2个客户端的20个请求，每个请求5秒这个WCF服务是如何托管的（IIS、Windows服务等）？我确实需要会话，我使用了大量来自服务的推送请求。我不确定模拟50个客户端调用时所需的验证级别。但是，ServiceThrottling可能是最好的起点。你也可以看看这篇文章，我认为我的配置在服务节流方面还可以，不是吗？太棒了！一行代码，一切都很顺利：D非常感谢！
