Apologies if this is in the wrong place or I've missed other threads similar (I did have a look but I don't exactly know what to look for).

I'm new to Silverlight especially wcf services etc. I thought I reached a point where I could publish my application which was primarily a learning exercise for myself. Everything compiled and when debugged in VS2010 it worked as I expected. However when I publish it I appear to have no connection to my remote database (or quite probably my wcf service). I've tried a few things that I've read around the net. but haven't been able to sort it out.

I have a feeling it will probably be a simple fix but I'm at my wits end. Is someone out there able to offer some advice on where to start or even better take a look at my project and point out the things I'm doing wrong?
