Deploying Silverlight 3-Tier App to 1 Server

Hi, I'm trying to deploy my Silverlight 3-Tier App to 1 server for testing purposes and I'm struggling to work out how to configure it.
I've created 2 web sites, one for the SL application (t2tdemo), and one for the application server (t2tappsrv).
I've copied the relevant files from Visual Studio into the directories.

I've also copied web.config into both directories (do I need it in both?)

I've modified the end point address in the t2tdemo website to point to the t2tappsrv web site.
I've modifed the sql connection string in t2tappsrv to point to the correct database.

When I run the app (t2tdemo) the Silverlight application loads correctly but when I do anything that needs to call a business object I get the following error:

Any ideas why?

Because they are in different web sites, you need to configure policy file for Silverlight to allow it to call a service on a different web site. The changes need to occur on the web site that hosts WCF service, not on the one that hosts SL app.

Ok, that makes senses. I've added the cross domain policy files now. But I'm still getting a similar error (see below).

Just a thought, do I need to recompile the app with those files in the solution?

sergeyb replied on Tuesday, September 01, 2009

I think the policy file is not quite right still. It is pretty clear judging from the error.
