.net mvc interview questions: ASP.NET MVC Interview Questions (With Sample Answers)


Answer ( 1 )


    When you’re interviewing for a position with a company using the ASP.NET MVC framework, it’s important to know the ins and outs of the technology. This will help you better understand what you could be working on if hired, and how your work might fit into that team’s vision for their product or service. Here are some questions from a recent interview:

    What is the advantage of ASP.NET MVC?

    ASP.NET MVC is a framework for building web applications, it’s a model-view-controller framework. It is based on the concept of separating different aspects of an application into three distinct parts: models, views and controllers.

    • Model: It represents data in your application and helps you to manipulate this data using classes. You can use it to represent database objects or simple POCO objects (Plain Old CLR Objects). Models are responsible for persisting themselves out to disk so that they may be retrieved later by other parts of your application such as controllers or views.
    • View: A view is responsible for displaying information about models in specific ways depending on what type of request was made by users accessing that page (GET/POST). Views typically contain HTML markup as well as Cascading Style Sheets (CSS) stylesheets which provide formatting instructions so that browsers know how elements should appear when displayed on screen–for example text color and font size could both be specified via CSS rules defined within a particular HTML tag such as .

    Explain what is model view controller pattern in .net?

    Model View Controller (MVC) is a software architecture pattern, used in software engineering to separate the presentation of information from the underlying data and logic. This separation of concerns allows independent teams to work on different aspects of an application while knowing that they are working with a consistent set of rules.

    The MVC pattern was originally designed by Trygve Reenskaug while working at Xerox PARC in 1979. The goal was to provide a framework where user interfaces were decoupled from data and business rules: as such, it’s often associated with web applications but can be applied any time there’s more than one kind of user interface for an application or website (e.g., mobile).

    Explain the ASP.NET MVC architecture.

    The ASP.NET MVC architecture consists of the following components:

    • Model – Models represent the data in your application. They are responsible for interacting with data sources such as databases and APIs, as well as converting that data into domain objects that can be displayed in views.
    • Controller – Controllers manage how user input is handled by an application, and they also handle responses from HTTP requests made to it by users (such as GETs, POSTs). The controller determines what action should be taken based on which method of its own class was called; if necessary it passes information back down through model classes before returning data back up through views so they know what content to display next time someone visits your site or app again later on down the road when there’s another request coming through again after some period of time has elapsed since last seeing them last (or even just minutes later if someone refreshes their browser window).

    What are the advantages of using ASP.NET MVC over Web Forms?

    • ASP.NET MVC is a better application structure. It has a cleaner separation of concerns and better encapsulation, which makes it easier to work with in large projects.
    • ASP.NET MVC is a better design pattern. The Model-View-Controller (MVC) pattern was invented by Trygve Reenskaug in 1979 and first used in Smalltalk-80, but it wasn’t called “MVC” until 2005 when Eric Raymond wrote an article titled “The Magic Cauldron.” In this article he described what he thought were the three main components of object oriented programming languages: objects, methods and messages (or events). This led him to conclude that all OOP languages should have these three things as their core elements; henceforth we can say that if any language lacks one or more of these elements then it isn’t truly object oriented!

    How does routing work in an ASP.NET MVC application?

    Routing is a feature of the ASP.NET MVC framework that enables you to map URLs to specific actions and controllers in your application. Routing is based on the HTTP protocol, which defines how web browsers communicate with web servers.

    The routing system allows you to create flexible URL schemes for your site so that visitors can easily navigate through it without having to remember complex URLs or paths.

    What are razor views in ASP.NET MVC?

    Razor is a markup language for creating dynamic web pages. It’s an alternative to the HTML markup language and it works on the server side. Razor is a part of ASP.NET MVC, which stands for Model-View-Controller pattern that separates your application into three distinct areas:

    • Models represent the data in your application (like User or Product)
    • Views display this data visually (such as a list of users)
    • Controllers respond to user input and provide logic for updating models

    Why should you choose Razor views over HTML views in an ASP.NET MVC application?

    You should choose Razor views over HTML views in an ASP.NET MVC application because they are more readable, easier to maintain and debug, secure and consistent.

    Razor syntax is based on C# which makes it easier for developers who are familiar with C# or VB.NET programming languages to understand the code. This also results in fewer bugs when compared with other view engines such as PHP or JSP because they don’t need any compilation step before rendering the output at run time like Razor does (you can just write everything directly on the page).

    What happens to a view if you remove it from the project or delete it from the database? How do you avoid that?

    If you remove a view from the project, it will be removed from the web server.

    If you delete a view from the database, it will be removed from the web server.

    You can avoid this by adding views to a separate folder in your project (e.g., ViewsShared). Then use that folder as part of your URL routing system so that when users request an action on one of these shared views (e.g., http://localhost:5000/Home/Index), they’ll get routed directly to their respective placeholders without any additional processing being done on those requests

    How do you share data between different controllers in a web application built on top of ASP.NET MVC framework?

    The ASP.NET MVC framework provides a number of different ways to share data between controllers in your web application. You can use the model to share data between controllers, or you can use the controller’s action methods and view events to do so. You can also choose to inherit from a base class in order to create a common set of properties and methods that all controllers in your application will be able to access.

    In addition, if you’re working with HTML views (instead of Razor), there are two more options available: including @model directives directly within each individual HTML file or using @inherits directives at the top level of each view file’s code-behind file

    You should aim for a job as a developer and not just be another number (or salary) on someone’s team

    As a developer, you have the opportunity to be a part of something special. You’re in high demand and can make good money doing what you love. But don’t just take my word for it – there are countless other developers who would agree with me!

    As an added bonus, as an ASP.NET MVC developer, you will have plenty of freedom and responsibility. As long as the work gets done (and done well), most companies will let their developers do what they want within reason; but even if they don’t allow this kind of freedom at first, eventually they’ll come around after seeing how productive it makes their employees feel when they’re trusted with more responsibility over time.
