34 ASP.NET MVC Interview Questions with Model Answers!

ASP.NET MVC Interview Questions

ASP.NET MVC is an open source software that implements the MVC (model-view-controller) pattern in user interface development, making it critical to other areas of development. A general knowledge of this coding language increases the chances of getting certain jobs. In this article, we discuss both general and detailed ASP.NET MVC coding language interview questions and provide helpful tips and sample answers.

10 General Interview Questions

Many evaluators start their question section with general, open-ended questions. Their goal is to assess the applicant’s general knowledge of ASP.NET MVC. The following list contains common questions on the topic:

  • What is MVC?
  • Can you explain ASP.NET MVC?
  • What are some of the properties of MVC?
  • Are there any disadvantages?
  • What is TempData in MVC?
  • What is a partial view?
  • What is the default route?
  • What is the variance among ViewData and ViewBag?
  • Can you list and define all filter types?
  • What does display mode do?

10 Interview Questions about Experience and Background

To healthier measure candidates, evaluators often need to identify how long you’ve worked in the field and how much knowledge you have. The following list contains common questions about experience and background:

  1. What developments have you been working on lately?
  2. Think of your biggest software development problem. How did you overcome it?
  3. If you’ve ever had a conflict with a fellow developer, how did you handle it?
  4. What is your general procedure for bug testing?
  5. Have you worked with .NET before?
  6. How long have you been working with .NET?
  7. Have you worked with ASP.NET?
  8. How long have you been working with ASP.NET?
  9. How long have you been working with C#?
  10. Are you familiar with developing on Windows, macOS, Linux or Docker?

10 Detailed Interview Questions

The following list includes more challenging and detailed questions that interviewers often ask:

  • What is Response.Output.Write() for?
  • What comes after Init() and before Page_Load() in the page cycle?
  • Can you list validators in ASP.NET?
  • When would you use the Compare Validator control?
  • Can you list and define session state management options in ASP.NET?
  • Can you write code to send an email from an ASP.NET application?
  • Can you write code to prevent the browser from caching an ASPX page?
  • Can you compose code to relate a theme to an ASP.NET application?
  • Can you list and define ASP.NET security controls?
  • Can you list the Repeater control templates?

In-Depth Questions with Model Answers

Here are model answers to detailed questions you might be asked in an ASP.NET interview.

What are the main built-in objects in ASP.NET?

Built-in objects allow developers to access information about the web server and individual web pages. They are often used in determining the causes of errors and other situations. Employers need their teams to understand what these objects are and how they work.

Example: “The main built-in objects in ASP.NET are Request, Response, Server, Application, and Session. They are used similarly to ASP.NET, but these objects are defined in new classes in the System.Web namespace.”

Explain how to prevent the browser from caching an ASPX page and display it in code.

Several software development employers want applicants to test their awareness in a sandbox. This question assesses the applicant’s knowledge of the subject and requires them to create code before the interviewer.

Example: “To avoid caching, I can place SetNoStore on the HttpCachePolicy object exposed by the cache property of the Response object.

Response.Cache.SetNoStore();

Response.Write(DateTime.Now.ToLongTimeString());”

I want to propel an email from an ASP.NET application. Can you arrange it?

Some questions require more action than loud answers. As in the previous example, this question asks the applicant to demonstrate their knowledge in the sandbox space.

Example:

“Mailmessage mailMsg = new MailMessage ();

mailMsg.From = “VictoryProgramming@gmail.com

“;

mailMsg.To = “GPalmer@gmail.com”;

mailMsg.Subject = “Email with interview test”;

mailMsg.Body = “Hello Mr. Palmer. Did this email work?”;

SmtpMail.SmtpServer = “localhost”;

SmtpMail.Send(mailMsg);###

Can you list all potential event handlers in Gobal.asax?

Global.asax files handle higher-level application events. Different situations require different manipulators. Applicants must fully understand these handlers. For this question, the employer only requires a list. There are many event handlers, and the more an applicant states at the moment, the better chance they have of impressing the interviewer.”

Example: “Even managers can be divided into two sets: application events and session events. Application events include Application_Start, Application_End, ApplicationAcquireRequestState, Application_AuthenticateRequest, Application_AuthorizeRequest, Application_BeginRequest, Application_Disposed, Application_EndRequest, Application_Error, Application_PostRequestHandlerExecute, Application_PreRequestHandlerExecute, Application_PreSendRequestContent, Application_PreSendRequestHeaders, Application_ReleaseRequestState, Application_ResolveRequestCache , Application_UpdateRequestCache. Alternatively, session events include Session_Start and Session-End.”

Can you explain the lifecycle of an ASP.NET page?

As ASP.NET pages run, they go through a lifecycle with different phases. Page life cycles are an integral part of the ASP.NET programming role. Enumerating and defining each phase is paramount.

Example: “ASP.NET pages typically go through about seven phases during their lifecycle. The first phase is the initial page request. This occurs when a user requests a page and ASP.NET decides to either compile it or load a version cache.

The second stage is the Top of the Page. This is when the request and response objects are created.

The third phase is page initialization, which triggers page panels and relates themes.

The fourth stage is Page Load, in which ASP.NET uses view and control state properties to set the control’s properties.

The fifth stage is to handle the Postback event, but it is only fired if the same page is reloaded.

The sixth stage is rendering. ASP.NET saves the display phase and writes the rendering output.

The seventh and final stage is to unload. The completed page is sent to the client and ASP.NET releases the page properties and cleanup follows.”
