Used ASP when it was still COM based, built a few websites for various compaines in the late 90s and early 2000s.

WebForms

Even used it more recently (2021/22) for Imprezza software - it was mostly a legacy system that was being updated and maintained.

MVC

Definately my most used method of web site development, have used it in all of my previous jobs.
