WCF合同实例 [英] WCF Contract Instance

问题描述

嗨

在Windows服务中，我正在parallel.foreach循环中创建WCF服务协定的实例.

在这种识别/验证方法中，它是在循环中每次创建一个新实例还是使用现有实例.

我们能否使用调试代码或跟踪来找到它

谢谢

>>每次在循环中创建一个新实例还是使用现有实例?

这个实例是什么意思?是客户端对象还是服务对象?我认为您的意思是服务合同实例.如果是这样，则取决于您如何设置InstanceContextMode.

共有三种模式.

PerCall:为每个客户端请求创建一个新的InstanceContext(以及服务对象).

PerSession:为每个新的客户端会话创建一个新的InstanceContext(并因此创建服务对象)，并在该会话的整个生命周期内对其进行维护(这需要支持会话的绑定).

单个:单个InstanceContext(以及相应的服务对象)处理应用程序生命周期内的所有客户端请求.

您可以参考下面的链接以获取更多信息.

Hi

In my windows service, I am creating instance of a WCF Service contract within the parallel.foreach loop.

In this how to identify/verify, does it creates a new instance every time within the loop or uses the existing instance. 

Can we able to find this using the Debugging the code or tracing

Thanks,

Abinesh

>> does it creates a new instance every time within the loop or uses the existing instance.

What do you mean by this instance? Is it client object or service object? I assume you mean service contract instance. If so, it depends on how you set InstanceContextMode.

There are three modes.

PerCall: A new InstanceContext (and therefore service object) is created for each client request.

PerSession: A new InstanceContext (and therefore service object) is created for each new client session and maintained for the lifetime of that session (this requires a binding that supports sessions).

Single: A single InstanceContext (and therefore service object) handles all client requests for the lifetime of the application.
