Just want to mention that some of the internals of this aren't great. There's absolutely no decoupling which makes testing very difficult and the contextual stuff is horrid. The components folder is also a cleverly hidden static ball of mud. I hope this isn't what they're teaching new developers as we'll have to spend a long time getting them to unlearn this in the future...
Could you give me an example of something that would be hard to test, and how it may look in another popular framework which is less decoupled? I want to understand this.
MVC is really easy to test. This example just completely ignores concepts as programming to interfaces, composition and single responsibility.
For some context -> The MVC Music Store was the default project that you would build to learn ASP.NET and EF concepts. You can build these projects yourself with the tutorials here:
