Top ASP NET MVC Interview Questions and Answers for 2023
ViewBag is dynamic property that takes advantage of new dynamic features in C# 4.0. In short, The ViewBag property is simply a wrapper around the ViewData that exposes the ViewData dictionary as a dynamic object.

In MVC, controllers define action methods and these action methods generally have a one-to-one relationship with UI controls such as clicking a button or a link, etc.
The lifetime needs to be the same as the requests do not live long. If it is possible to wrap the whole request in one transaction, it can help comply with ACID principles. ORM (object-relational mapping) framework is a framework that helps in https://remotemode.net/become-a-net-mvc-developer/ reducing the amount of handwritten code in a web app. ORM is used when there are no extreme performance requirements, but frameworks like Dapper can be used in high-load systems. We can also enable the client-side validation programmatically.
It allows for the easy creation of web applications by utilizing a model-view-controller (MVC) design pattern. However, you can use your own specific programming languages, including Ruby on Rails, .NET, Java, amongst others, for solving MVC interview questions. Area is used to store the details of the modules of our project. This is really helpful for big applications, where controllers, views and models are all in main controller, view and model folders and it is very difficult to manage.

The route’s name is the first parameter to the MapRoute; the second parameter is the pattern to which URL matches, and the third parameter is default values for the placeholders. It is the right situation to inspect permissions or check for an active session. At the same time, afterFilter() is called after every rendering is done and after every controller action. The HandleErrorAttribute class is an example of an exception filter that implements IExceptionFilter.

They are like webforms controls as both HTML helpers and webforms return HTML. POST action type submits data to be processed to a specified resource. We pass the essential URL and data with all the POST requests. In layman’s terms, the partial view allows rendering a view within the parent view.
Write code to define methods in AngularJS Controller?
It is used to develop high-performance, scalable, robust web applications, content management systems, e-commerce websites, social media platforms, and more. With its ability to offer flexibility, customization, and control over web applications, ASP.NET MVC has become a preferred choice for developers and businesses alike. It is a Java framework which is used to build web applications. Not just that, it also implements all the basic features of a core Spring Framework like Inversion of Control, Dependency Injection. Spring MVC provides a dignified solution to use MVC in Spring Framework by the help of DispatcherServlet.
- If yes, then it simply uses the cached copy instead of fetching a new one from the server.
- If the placeholder values are unknown, the third parameter can be their default values.
- The backend is an ASP.NET Core or ASP.NET MVC application (server side).
- It likewise follows a code-behind design, for example, the ASP.NET pages, despite the fact that it doesn’t have a user interface.
In their response, each applicant may provide definitions or give examples of how they would use these features in a web application. The application deployment process requires a windows server with an installed IIS manager. You need https://remotemode.net/ to use the IIS manager to perform deployment after the development of the applications. Without deployment, you can’t bring any application to the market; thus, the IIS manager plays a primary role in completing this process.
MVC interview questions range in topics from view, model, and controller functions to scaffolding, route constraints, and authentication forms. The View logic takes care of the data’s display, aka the user interface. These views are created from the model data and various other methods.
- This class receives incoming requests and maps them to view models and controllers.
- This class is inherited from the “ActionResult” abstract class.
- We recommend having a senior .NET developer conduct these interview round.
- It also supports many authentication providers such as social media and enterprise identity.
- The central role of Action Filters in ASP.NET MVC is the execution of filtering logic after an action method is called.
- Here Json is provided one argument which must be serializable.
For client-side validation, the values of above both the keys must be true. When we create new project using Visual Studio in MVC3 or MVC4, by default the values of both the keys are set to true. ASP.MVC is a web application framework that is lightweight and has high testable features. ASP.NET supports 3 different types of components namely Model, View, and Controller. Imagine transforming every interview into a strategic advantage. Dive deep into every conversation, free from the distraction of note-taking.
Explain what is routing in MVC? What are the three segments for routing important?
ASP.NET (Active Server Pages . NET) is a progressive new programming framework that empowers the rapid improvement of powerful web applications and administrations. For .NET development roles, ask them to demonstrate their understanding of software development methodologies like Agile for example, and the tools they use like GitHub. Also, ask or test them on communication skills, teamwork, task management, aptitude, and attitude. Developers on specific project-based skills like testing, code security, debugging, coding style, etc. Routing determines how incoming HTTP requests are matched to specific actions or endpoints a web application created with ASP.NET Core. This allows developers to define custom URL patterns as well as route parameters.
