Top .NET Interview Questions and Answers

Do you want to be in demand? Be a .NET developer. Companies are struggling to find qualified candidates for these roles for a number of reasons, giving you the advantage as a job seeker. And you don’t need an advanced degree to land a .NET developer job. You need training and knowledge, yes, but it’s a field open to just about anyone working in IT.

That strong job demand doesn’t mean you won’t have to go through the interview process, however. You might be a qualified candidate, but employers are picky about their .NET developers and they are going to want to make sure you are the right person for the job. That means you need to both get the .NET training and do your homework prior to answering your first .NET interview questions. 

To make the latter easier, you might be hoping to find a list of .NET interview questions and answers on the Internet, so you can simply study those. However, it’s near impossible to provide you with a setlist of definite .NET interview questions and answers, because the range of technical skills needed is so broad. One employer might need SQL knowledge while another employer might need developers for macOS or Linux. An organization might need someone to build for the web, or for the desktop, or for mobile devices—or even the cloud. 

The possibilities are just about endless, which is one reason employers struggle to hire qualified candidates. Does that mean you can’t prepare for your interview? Of course not. There are many steps you can take to prepare for your job interview, no matter the job. In addition, you can prepare to answer general .NET interview questions that might be asked during an interview. 

With that in mind, we pulled together some .Net interview questions for you. Read through these and prepare your answers ahead of time, and you’ll walk into that job interview with confidence that will help you make a positive first impression and convince the interviewer you’re the right person for the job. 

Q: What is your training as a .NET developer?

Since .NET is not usually taught in college, interviewers are used to hearing that a job candidate learned Dot NET some other way, such as through a certification. Be specific when describing what kind of training you’ve had, even on-the-job training. Show your understanding of object-oriented programming (OOP) and Common Language Runtime (CLR). Talk about how you learned to design and maintain good quality code, or how you learned to automate testing. And if you’re using .NET for personal projects, talk about that too. Interviewers are increasingly open to hearing about a wide range of ways of learning these days because .NET is not formally taught in school. 

Q: Which programming language(s) do you know best? 

As a Dot NET developer, you need to know either Visual Basic or C#. To really stand out, you should know both, and other languages won’t hurt! Although the job title is developer, .NET is not a programming language, as you know. So you need to show your proficiency in the language you know best, and maybe talk about how you learned it, plus the benefits and drawbacks to it—to demonstrate deep knowledge. (If you don’t know C#, you can easily learn it.) 

Q: Explain the .NET framework.

.NET acts like a stage for producing different applications on windows. It bolsters distinctive languages namely, C#, VB, Cobol, etc. This framework has a rundown of inbuilt functionalities such as class, library, and APIs which are utilized to construct, send and run web administrations and distinctive applications. 

Q: What are the essential components of .NET? Explain.

The parts of .NET are Common Language Runtime, Application domain, .NET Class library,  Common Type System, .NET structure, Profiling, etc. CLR gives building squares to a wide assortment of uses. The class library comprises an arrangement of classes that are utilized to get to the regular usefulness. The usefulness can be shared among various applications. Be that as it may, the two critical parts are Class library and Common Language Runtime.

Q: Which .NET tools do you know? 

When it comes to tools, only you know what you know! Be ready to talk about the tools you know and use, like code versioning tools such as Git or SVN, any frameworks or libraries, the Visual Studio tools you might be familiar with, .NET command-line tools, Mono, .NET Core, etc. Prepare for your .NET interview questions by being ready to talk about the tools and how you’ve used them.

Q: What is your .NET development experience? 

We can’t answer this .NET interview question for you, but we can coach you to be ready to answer it. The better prepared you are for your .NET job interview, the better you’ll perform. Think through all your past experiences and choose to highlight whatever is most relevant to the position you’re interviewing for. Also highlight any specialized skills that might help you stand out, such as being able to write reusable libraries or your knowledge of concurrency patterns. Do you have experience with popular web application frameworks or Windows Presentation Framework? Be prepared to talk about it. Being a .NET developer can mean a lot of different things and your interviewer could be making assumptions about you. Make sure your experiences are played up in the best possible way so they are clear on what you’re capable of.

Q: Can .NET support multiple languages? If so, how?

A language ought to conform to the Common Language Runtime standard to wind up a .NET language. In .NET, a code is aggregated to Microsoft Intermediate Language known as Managed Code. This code is then run in a .NET environment and after the compilation to the Intermediate Language, it is not an obstruction anymore. A code executed in the following manner can use a function or call in any other language.

Q: What are the different Session State Management that is available in ASP.NET?

Q: Explain State management in ASP.NET.

State Management means maintaining the state of the object. The object here refers to a web page/control.
There are two types of State management, Client Side, and Server side.
Client-Side – Storing the information in the Page or Client’s System. They are reusable, simple objects.
Server Side – Storing the information on the Server. It is easier to maintain the information on the Server rather than depending on the client for preserving the state.

Q: Do you consider yourself to be a team player? 

Despite the stereotype of the IT person off in a cubicle working in isolation, today’s .NET developer will probably be part of a team and therefore needs good communication skills. Demonstrate your ability to work with others, citing specific examples if you can. 

These are admittedly general types of .NET interview questions and answers. You probably won’t find a list of specific .NET interview questions because—as noted above—an employer can be looking for any number of skill sets, prior experience or expertise. Reading through these .NET interview questions and preparing your answers, plus taking other steps to prepare yourself, will help you to come across as confident and self-assured, no matter how technical or specific the questions might be. 

Increase Your .NET Knowledge First

And what about your .NET knowledge? Is it all it should be? Before walking into your first .NET interview, consider giving both your knowledge and credibility a boost with a certification. A certification can help you review your .NET knowledge, teach you new skills, and give you something substantial to add to your résumé.
