15 Essential ASP NET MVC Interview Questions and Answers

The “default” view engine for ASP.NET MVC uses the same .aspx/.ascx/. Let’s begin this MVC interview questions with beginners level questions first. For the next two years, he was part of a large and remote scrum team for an enterprise client working with Java technologies and Adobe Experience Manager. Lately, he’s been focusing on AWS microservice architectures. He has over two decades of experience designing and developing sophisticated enterprise web applications using various technologies, most recently with ASP.NET MVC. Authorization, custom action filters (sync and async), and action result transformation can be done with the same approach.

Cons involve potential naming conflicts and difficulty in sharing code between features. ASP.NET MVC is a web application framework implementing the Model-View-Controller (MVC) architectural pattern. In this pattern, Model represents data and business logic, View displays data to users, and Controller manages user interactions and updates between Model and View. Our ASP.NET MVC coding tests and interview questions implement RealLifeTestingTM to present a simulated version of a developer’s average workday. They are then set challenges to face within that simulation.

What are the types of Authentication in ASP.NET?

Additionally, the framework includes multiple templates, including page templates, field templates, , entity page templates, and filter templates. These templates permit you to design and build a fully functional website. But, one drawback of this feature is that it can’t access the page model and can operate on the passed arguments. Thus, the best application of this feature is to use it to render reusable pieces of pages that might consist of logic. Use this feature through dependency injection, which makes it robust and reusable. The application deployment process requires a windows server with an installed IIS manager.

In this article, I list the top 50 MVC questions and their answers. The answers are code examples written by authors of C# Corner. ViewBag is a dynamic property that uses C#’s dynamic feature.

Name some OOP languages?

They provide an advantage over using the HTML elements since they can be reused across the views and also requires less coding. There are several builtin helper methods that are used to generate the HTML for some commonly used HTML elements, like form, checkbox, dropdownlist etc. Also we can create our own helper methods to generate custom HTML. First we will see how to use the builtin helper methods and then we will see how to create custom helper methods. I will use two approaches in this article to validate a model data.

It is helpful when we want to transfer a value from one page to another page. If the sending data is in large quantity then we can not use Request.QueryString because it supports only 255 characters. We use the ‘&’ special character for separate multiple query https://remotemode.net/become-a-net-mvc-developer/ strings. Any query string that was available to the calling ASPX page will be available to the called ASPX page. A custom control is one that is made or created by the programmer to serve the business needs, by extending the functionality of existing controls.

If you place the log.txt file in the ~/bin/ folder of an ASP.NET MVC application, will it affect the app?

In ASP.NET MVC, HTTP GET and POST verbs are used to handle client requests. The primary differences between them lie in their purpose, data handling, and idempotency. Custom model binders can be created by implementing IModelBinder interface for specific scenarios. Web Forms, an older technology, relies on event-driven programming and uses a complex page lifecycle. This can lead to less maintainable and harder-to-test code compared to Razor’s simpler approach. Additionally, Web Forms use ViewState, which increases page size and load times.

• Application_Start is triggered when the application starts, enabling initialization of resources or configurations.
• Its default value is “Any”, however there are the following locations available; as of now, we can use any one.
• Hence, the number of proxy/client requests to the web server is reduced.
• The following figure shows how ValidationSummary displays the error messages.
• Cons involve potential naming conflicts and difficulty in sharing code between features.

This is a popular and useful tool for debugging which tracks the speed details, url details etc. URL Pattern — Placeholders will be given to match the request URL pattern. UpdateTargetId — Target element which is populated from the action returning HTML. In ViewBag no need to typecast the objects as in ViewData. “BundleConfig.cs” in MVC4 is used to register the bundles by the bundling and minification system.

This return type is used when we want to redirect to any other action method. This return type is used to return a webpage from an action method. Depending on the URL sent “UrlRoutingModule” searches the route table to create “RouteData” object which has the details of which controller and action to invoke. Typically controllers read data from a view, control user input, and send input data to the model. Methods that return HTML string are known as HTML helpers. They are like webforms controls as both HTML helpers and webforms return HTML.
