Let me try this one more time.
I am fully aware of the fact that ESRI is working an a configurable Silverlight viewer that is currently in beta form and that this forum is about the Silverlight API. Since I don't have access to the beta software, I need to know if the dll this posting is about is actually from the beta product? Reason being, someone is providing a free configurable silverlight viewer and is using the aformentioned dll.
