Proxy class not available for Windows Phone 7 Reference to WCF Service

Question

I have an existing WCF service that works. I've added a reference in Visual Studio 2010 for my Windows Phone app. The reference shows up and I see the methods when I check out the properties of it. The service is using basicHttpBinding. It seems the proxy class is never generated. I cannot reference it (yes - I'm checking the proper namespace)

I'm aware of the SlSvcUtil.exe utility - but that is supposed to not be necessary anymore. Any thoughts as to why my proxy class isn't being generated but the service reference is there?

Thanks!

If you select the "Project -> Show all files" option when selecting the WP7 project, and you expand the service reference icon, do you see the reference.cs file? — carlosfigueira
Is there anything under the svcmap file (IIRC the .cs file is listed under that)? If not, is there any warning / error on VS when you add the reference? If not, then it may be worth trying to use slsvcutil to generate a file - even if just to find out if it emits any error / warnings. — carlosfigueira
ah ya.. an empty reference.cs under the svcmap file. I had tried the slsvc util previously and it works just fine (no errors and a proper cs file), but the add svc reference is 'supposed' to work just fine now so trying to figure out the cause of that. — Adam Tuliper - MSFT

This has happened to me.

Not sure what causes it.

What works for me is to close down Visual Studio, reopen, right click on the service and click Update Service Reference.
