Working with Areas in MVC Application
The primary purpose of areas in MVC is to separate and manage Model, View, Controller, Themes and routing registration file into separate sections. In other words, areas serve as a technique for dividing and managing a large Application into well managed smaller modules with the separate M-V-C in each module.
Why to use areas in MVC Application
If you are building a CRM Application for a small Educational Consultancy with multiple business units such as Registration on Arrival, Information Gathering by Receptionist, Updates by Consular, Documentation Management, Interview Preparation, Billing, and Report Generation by different departments etc. Each of these units have their own logical components views, controllers and models.
