I have a Clustered Windows Hosting site which currently hosts an MVC Web Application using a MYSQL backing database.
What I have been trying to do for the past three weeks is host a WCF Data Service exposing the database behind the website to be consumed in a WPF application which will be installed on Windows machines.
I have followed every single tutorial that I have come across. None of them have worked and all of them give the example of using http://localhost as the location of where the Webservice is called from.
I have limited experience with Asp.Net and MVC but have published working websites before and as I mentioned currently am running a fully functional MVC web Application. I also have extensive .Net knowledge and experience, but, for the life of me cannot fathom this out at all.
I have seen no real examples of a WCF site being hosted from within a clustered hosting scenario. Practically every example I see mentions using IIS, but I do not have access to IIS on my hosting.
Could anyone point me in the right direction to a tutorial that will allow me to use a WCF service, or am I completely barking up the wrong tree?
Okay, an Update: After much experimenting I came across the following attribute and used it
[System.ServiceModel.ServiceBehavior(IncludeExceptionDetailInFaults = true)]
This gave me an error which appeared to indicate that the Data Service was trying to access files on my local hard drive, indicating that I’d fudged some kind of reference. I also realised that I hadn’t set up the Membership profiles and so scrapped my Data Service starting again.
First I added the Asp Membership profiles, then the Entity Model, set the permissions and used that attribute again and although looking more hopeful still got the following error.
The exception message is ‘The specified store provider cannot be found in the configuration, or is not valid.’. See server logs for more details. The exception stack trace is:

Although, still not able to use it. This is giving me more hope than previously. Again, if anyone has any suggestions, I’d be grateful to receive them.
I have actually managed to solve this. I’d post the full answer but can’t due to sever formatting problems with the editor here so I’ll have to do the short version.
Basically, I removed the MySQL version that I was using, downloaded the latest version and installed and added that reference.
I also added to the web.config a DbProviderFactories linking to the MySQL reference. Like I said, I’d post the code but this formatting system keeps rejecting my attempts.
