Since couple of months we are working on a new project based on Asp.Net 3.5 Framework which is using Backbase as a client rendering framework. Backbase provides a rich user interface which is independent of development platform. It sure has a learning curve but once you are through that phase you will see the real advantage of RAD.

If you are trying to use Backbase with Asp.Net and have any questions then I may try to answer them since we have passed that phase of sorting out initial hiccups.
