Is anyone familiar with the Publish-Subscribe project It's available online and I think it was written by people from IDesign.
I'm trying to figure out ways to save the Transient Subscribers info in the database in case the host server goes down. I've noticed the list of transient subscribers are retrieved by:
T subscriber = OperationContext.Current.GetCallbackChannel<T>().
Is it possible to save the subscriber data in the database
Thanks.

The IDesign Demo offers as persistent subscriber as well, if you downloaded the demo off of the idesidn site it should have came with it, including SQL scripts.
