I have a Silverlight application for a container / wizard. This container dynamically loads xaps and accesses specific user controls in loaded xaps. Some of these user controls invoke the WCF service hosted on the server.
The following error occurs when the user controls the loaded xap call to the WCF service:
System.InvalidOperationException was unhandled by user code
Message=Cannot find 'ServiceReferences.ClientConfig' in the .xap application
package. This file is used to configure client proxies for web services, and
allows the application to locate the services it needs. Either include this
file in the application package, or modify your code to use a client proxy
constructor that specifies the service address and binding explicitly. Please
see inner exception for details.

The exception tells me that it ServiceReferences.ClientConfigdoes not appear in some way ... although it is packaged in a loaded xap.
I saw posts that suggest it ServiceReferences.ClientConfigwill be packaged with an xap container, and this approach will work. However, I'm not sure if this is a neat solution.
