I was able to create my first MVC module for DNN Platform 9. The only issue is that I don't want to use razor for my view engine. I would like to use the classic ASPX view engine and I'm having a lot of trouble trying to figure that out. Does anyone have any experience or tips if I can make that work?

This is the error message I get right now:
