Constructing a Silverlight app based on Rolodex

The first step would be to figure out if WCF call gets to the portal.  The easiest way probably is to use the following debugging configuration.  Run yor app, then look at c:\traces.svclog.  If it is empty, your call never gets to the server.  At that point you probably want to step through client call code to see where it fails.  Setting break on all exceptions would also help.

Add the following to web.config file to web site that hosts WCF service.

<system.diagnostics>
        <sources>
            <source name="System.ServiceModel"
                    switchValue="Information, ActivityTracing"
                    propagateActivity="true">
                <listeners>
                    <add name="traceListener"
                        type="System.Diagnostics.XmlWriterTraceListener"
                        initializeData= "c:\Traces.svclog" />
                </listeners>
            </source>
        </sources>
    </system.diagnostics>

So I am on this epic quest to port an existing CSLA app of mine from using a Windows Forms front end over to Silverlight. I have setup the solution structure in the same way that the Rolodex sample app is build. Everything compiles and appears to be running fine (no runtime errors) but when validating the credentials on the login screen, it appears that DataPortal_Fetch in xxxIdentity never gets executed.
By never executed I mean that within DataPortal_Fetch I am throwing and exception and even trying to output some text to the console but none of the 2 happen, I just get a message back on my UI that logon was invalid. I tried to set a breakpoint in the Rolodex example to see how you get into the DataPortal_Fetch method but it appears that because of the directives that point would never be hit (is there any way of switching this while debugging?)
The ServiceReferences.ClientConfig (in the Silverlight project) and Web.config (in WcfHostWeb) seem set up correctly as is the port used for WcfHostWeb.

Any ideas?

Yes, you can debug server side code.  It is easier if WCF is hosted in the same web site as SL application.  If not, you can start another instance of VS and attach debugger to Cassini base on port number that WCF host web site is running on.  At that point you should be able to hit your  server side breakpoints.

This was stopping me from progressing so I took the Rolodex app itself and started modifying it bit by bit to see where the error would reappear (if it did).

After a lot of tampering it finally worked (the DataPortal_Fetch() was called wherein I was hard-coding the authentication). But then I implemented the check (query to database) and I started getting the same problem, which is I just got a message that logon was unsuccesful...

The problem here is that I cannot step into the code of my DataPortal_Fetch() method as the breakpoint is never hit. I am new to Silverlight so am not sure if:

1. It is possible to debug server side code
2. If it is, what settings I need to change.

Could someone kindly answer?
