Why can’t my brain grasp ASP MVC?

Simple stuff.

1. Request come to server

2. It's passed to router

3. It decides which controller and action will handle it

4. Framework binds the incoming data (Query, JSON, Form...) to the model

5. Action method runs and returns view/data

Some stuff is also executed before and after action method, like filters, middlewares... But this is the Flow...

Also good practice is to put app logic (data access/algo) in separate .dll and maintain Layered architecture. I usually go for 4-5 layers:

Data.dll <- Entities

Dal.dll <- Repositories

Core.dll <- Logic

MvcProject.dll <- Asp here

Also some Common.dll for shared stuff.
