Forget what I said in my last post. Well… not all of them. What I posted before works! and that’s the way to do it if you want to enable asp.net trace in your WCF services.
So what’s wrong with that? The problem is that if one of your services uses something from the session, asp.net starts using a lock mechanism so two process don’t step over each other. In other words, you won’t be able to have two services running at the same time… if you make two calls ‘at the same time’, the first one to reach the server goes in and the second one waits for the first one to finish. And that’s not acceptable in my case.
