A lot of the changes are aimed at making it easier for people to get started with Asp.Net, and most of those aren't breaking changes. Traditionally Asp.Net has had a lot of boilerplate around project setup and configuration, and things like minimal APIs aim to change that. The unfortunate side effect is that it adds more complexity (more ways to do the same thing) to the ecosystem, and the newer minimal approaches probably aren't what you're see used in the typical production project.
