Is this that web framework from Microsoft that hid the transaction-orientedness of HTTP from you by letting you set server-side click listeners on buttons and generated all the code needed to glue it all together? At the time, I didn't feel good about it because it abstracted away too much, and required Windows on the server. Little did I know about all the ways people would start abusing JS in 10 years.
