Hi John

I would like to add my thanks to many others for your work on Silverlight, which I have found so useful. WRT this video, I am using RIA services and would like to use a custom Fault to inform a Silverlight client about a data concurrency error. However the RIA Services domain service code seems to have a generic DomainServiceFault baked in to the generated code. Also, whatever kind of exception is raised in the WCF service a DomainException is raised on the Silverlight Client. Do you have any RIA service specific advice for when we want custom faults? Thanks...

Anthony
