Detect WCF client open channel operation

I read the article in this site related to WCF Channel Listeners. I suppose that (correct me if I'm wrong), after a service opened a channel, it is possible to detect a request of connection made by a client. In practice I would like to detect when the client calls the Open method.

Could you tell me how can I 开发者_JAVA技巧do that please?

Thanks in advance.

For everyone interested in this question, I had an answer in this post.
