Damir, in his Self-Hosting of WCF Services, writes about advantages and disadvantages of self-hosting WCF services. His conclusion is that you should not use self-hosting services in Enterprise or Production scenarios. And I agree on that - at least for todays projects. But I expect in the near future more and more "talking" applications and I think the self-hosting would become more usefull. I can imagine Service Bus as hosted service and many applications from different devices which will use self-hosted services.
What do you think? Do you have any self-hosted service in production today?
