>Hi all, I've just written my first MVC web app ( I'm teaching myself ) and also created a WCF service to handle the comms to SQL server , I've ( for testing purposes ) hosted the WCF service in a Windows service and all works tickety boo :-). What I would like to do now is, host the WCF in IIS and have it start on demand. What's the besy way of doing this ? I've got IIS and IIS Express installed ( on my local PC ). Many thanks.

Since you've already got the service you can skip that part :-}
