RIA Services Server Side Exception Handling

I am trying to find out a way to handle unhandled exceptions at server side. I want control over exception handling at Domain Service level so that when any operation is called then I can log the exception and wrap it in some beautiful words to send it to the client. I found many ways for WCF and classic web services but nothing for RIA services. Please provide your suggestions.

You need to override the DomainService.OnError method as described in this WCF RIA Services Exception Handling blog entry. I've done this in a base DomainService class rather than in each individual DomainService class in my application as shown below. The errorInfo.Error property does not have a setter so I don't think you can replace the exception object with your own, but the <system.web><customErrors mode="On" /> config element can prevent the details of the exception being exposed to the client.

[EnableClientAccess()]
public class DomainServiceBase : DomainService
{
    protected override void OnError(DomainServiceErrorInfo errorInfo)
    {
        Logger.WriteException(errorInfo.Error);
        base.OnError(errorInfo);
    }
}
