So unfortunately I wrote this post many years ago and the code is all lost. Sorry! You can try the StructureMap mailing list, however.

Thanks for this article. Is it possible for you to upload the solution as well?
To tell truth I’m a newbie to StructureMap and I would like to use for a scenario where there are multiple Service projects with each project potentially having multiple service contract implementation (such as PingService, CustomerService, AssetService, CalculationService) and finally a Web application that has all the service files (i.e. multiple .svc files)
I want to use StructureMap on WCF so that but have it all registered in one place (i.e. inside web application) and I don’t know how it works.
Thanks for your help

Yep, the contextual session seems to be the way to go. Let me know how it goes!

Hey Jimmy… referring back to my comment from last month – I spiked implementing this and I was completely dumb in thinking I could depend directly on the ISession interface in my repository! The reason is that repositories are usually configured as singletons – therefore even if the session is per-call you’re still gonna get the same instance for your repositories and everything will come crashing to a halt!

Anyway I actually think Frank’s suggestion is best – defining a context for NHibernate’s GetCurrentSession() method and delegating that to an IExtension in WCF. That is what I am going to propose to the rest of my team anyway!

Cheers
Neil

Hi there,
I thought I add some more spice to this by pointing to my post today – (http://realfiction.net/?q=node/167)
I thought we should have honorable mentions of NH’s possibility to define a class that provides a “Current Session” (which you get via sessionFactory.GetCurrentSession()) as well as making use of the WCF InstanceContext. Cheers!

I dunno, I’ve never really tried going through a container. Since it always has to be built from an ISessionFactory, it just made more sense to me to wrap it all up. Have you been able to get it in through the container?

@Paul, @Mike

The other problem I’m running into is that I have a hard time testing anything multi-threaded with any consistency. Unless I can write a good test for it, I just have a tough time convincing myself it works.

Hi, can you explain why you need the ISessionBuilder in first place. Why can’t you make the ISession a direct dependency of the repository, and then get your container to pass a shared instance to all your repositories. So your constructor would simply be

public ProductRepository(ISession session) { _session = session; }

Yeah a double check lock will definitely do the trick. The ye olde enterprise nhibernate sample on codeplex does it an interesting way using a nested type. But I agree that as soon as you do it on type initalization the exceptions are more of a pain to work with.
