Prepare Top 25+ Most AskedImportant MVC Interview Questions

In Asp.net MVC, we can easily apply validation to the web application by using Data Annotation attribute classes to the model class. Interview questions on MVC can be easy if you prepare well, and that also goes for MVC interview questions and answers for experienced individuals. It follows the MVC design pattern using the basic features of a core spring framework, including dependency injection and inversion of control.

This question is designed to assess your knowledge of exception handling in C#, which is vital for ensuring robust and fault-tolerant applications. It also demonstrates your ability to adhere to industry standards, minimize errors, and provide smooth user experiences. Spring MVC is a Java framework that follows the MVC design pattern and builds web applications. It implements all features of a core spring Framework like Dependency injection and inversion of control. With the help of DispatcherServlet, Spring MVC provides a dignified solution for using MVC in Spring Framework.

What is JsonResultType in MVC?

The HttpClient class gives you a base class that you can use to send HTTP requests and get HTTP responses. HttpClient sends and gets information from the local IIS mvc developer server’s Web API URL. Requests for web resource files like Webresource.axd or ScriptResource.axd cannot be delivered to the controller using the default route.

The main objective of the MVC design pattern is the separation of concerns. It means the domain model and business logic are separated from the user interface (i.e. view). Thus, maintenance and testing of the application become simpler and easier. Output caching in https://remotemode.net/ .NET MVC allows MVC developers to cache the output of controller actions or partial views, reducing the need for repeated computations or database queries. Custom model binders in .NET MVC allow devs to control how data from HTTP requests is bound to model objects.

Q21: Can you explain ASP.NET MVC life cycle?

The Exception filters are executed when an exception occurs during the action execution or filter execution. The IExceptionFilter interface is used to create an Exception Filter which provides the OnException method which will be executed when an exception occurs during the action execution or filters execution. This is one of the most frequently asked ASP.NET MVC Experienced Interview questions.

Once I can reliably replicate the problem, I use a combination of tools such as Visual Studio’s debugger, logging mechanisms, and performance profilers to narrow down the root cause. I also leverage my knowledge of the application architecture and codebase to identify potential areas where the issue might originate. During this process, I pay close attention to any recent changes that could have introduced the problem. Asynchronous programming, on the other hand, allows multiple operations to run concurrently without blocking the main thread. In C#, this is achieved using async and await keywords, which enable non-blocking code execution.

Discuss the Role of Action Filters In .NET MVC and Provide Examples of their usage

To identify the root cause, I first analyzed the existing codebase to pinpoint any inefficient queries or bottlenecks. After thorough investigation, I discovered that the primary issue was related to multiple database calls being made for each filter applied by the user, which significantly increased the response time. The interviewer wants to gauge your leadership skills and your willingness to help others grow within the company. As a senior developer, part of your responsibility is to share your knowledge and experience with junior team members. Being able to guide, inspire, and mentor less experienced developers is vital to building a strong team and ensuring a successful project outcome. Your answer will reveal your ability to foster collaboration and contribute to a positive work environment.

• This book also helps you to get an in-depth knowledge of ASP.NET MVC with a simple and elegant way.
• It automatically maps properties between objects with similar names and structures, thus reducing the amount of manual mapping code and improving development productivity.
• By default the above code snippet will be present in all of our examples so that we can show just the specific angularJS code in the subsequent sections.
• At runtime, the process identifies the user agent, for example IE, Mozilla, etc. and then removes whatever is specific to Mozilla when the request comes from IE.
• This includes conducting regular code reviews where everyone can provide constructive feedback and learn from each other’s perspectives.
