Explain The Advantages Of Asp.net Mvc Over Asp.net?
Provides a clean separation of concerns among UI (Presentation layer), model (Transfer objects/Domain Objects/Entities) and Business Logic (Controller).
Easy to UNIT Test.
Improved reusability of model and views. We can have multiple views which can point to the same model and vice versa.
Improved structuring of the code.
What Is Separation Of Concerns In Asp.net Asp.net Mvc?
It is the process of breaking the program into various distinct features which overlaps in functionality as little as possible. ASP.Net MVC pattern concerns on separating the content from presentation and data-processing from content.

afterFilter(): This function is called after every controller action, and after rendering is done. It is the last controller method to run
Explain the role of components Presentation, Abstraction and Control in MVC?
Presentation: It is the visual representation of a specific abstraction within the application
Abstraction: It is the business domain functionality within the application
Control: It is a component that keeps consistency between the abstraction within the system and their presentation to the user in addition to communicating with other controls within the system
Explain the role of “ActionFilters” in MVC?
In MVC “ ActionFilters” help you to execute logic while MVC action is executed or its executing.
Explain what are the steps for the execution of an MVC project?
The steps for the execution of an MVC project includes
Receive first request for the application

Explain what is Model-View-Controller?
MVC is a software architecture pattern for developing web application. It is handled by three objects Model-View-Controller.
Mention what does Model-View-Controller represent in an MVC application?

Model– It represents the application data domain. In other words applications business logic is contained within the model and is responsible for maintaining data
View– It represents the user interface, with which the end users communicates. In short all the user interface logic is contained within the VIEW
Controller– It is the controller that answers to user actions. Based on the user actions, the respective controller responds within the model and choose a view to render that display the user interface. The user input logic is contained with-in the controller
Explain in which assembly is the MVC framework is defined?
The MVC framework is defined in System.Web.Mvc.
Explain what is routing? What are the three segments for routing is important?
