Essential ASP.Net MVC Interview Questions and Answers

Q1. Have you ever implemented MVC? What do you think it is more suitable for; Web or Windows Application?

Q2. What is difference between ASP.NET MVC and ASP.NET WebForms?

WebForms lack separation of concerns, which means the code and .aspx page are tightly associated with each other. This creates errors when the developer attempts to change one without impacting other.

However, ASP.NET MVC has a separation of concerns, which means that one aspect or component can be changed without disturbing other.

Q3. What is MVC Routing?

The URLs in ASP.NET MVC are mapped to action methods and controller instead of physical files of the system. To accurately map action methods and controller to URLs, the routing engine forms appropriate routes. Using this, the controllers can handle specific requests.

Controllers define action methods for URL mapping. Every request received by the MVC application is managed and responded to by action methods.
