What to look for in .Net framework developers

.NET is a software development framework created by Microsoft. It was produced as Microsoft’s response to the popularity of the Java platform. .NET allows software to be easily developed, installed, and executed on Windows-based operating systems.

Your .NET framework developer should know of the varying .NET versions and the differences between them. They should also have demonstrable knowledge of the languages the .NET framework supports including C#, Visual Basic .NET, F#, and C++ .NET. There are a large amount of libraries and frameworks available to .NET developers and it is helpful to have a good knowledge of at least some of them, including .ASP.NET, MVC, or Entity Framework. They should also know about the various types of frameworks associated with .NET; Web frameworks, Desktop frameworks and Communication frameworks.

Commercial experience is important in a .NET framework developer.  You will want your candidate to have hands-on experience with a project that used .NET technology, even if that is not in a commercial sense.

.NET evolves quickly. The.NET Core framework, that supports  Windows, Mac, and Linux is similar to the .NET framework, but has its own nuances. One shouldn’t be seen as a replacement for the other. A .NET developer should be able to get to grips with using .NET Core easily enough.

Our .Net framework interview questions and tests will be able to assist you in narrowing down which candidates really have the knowledge needed to be your next .NET developer.

Want proof that our .Net framework interview questions and tests work?

It is understandable to want to seek assurances that our screening tool works before committing your company’s money. Check out this case study of one of our past clients for a little extra motivation:


DB1 develops robust and reliable software solutions for medium and large companies.

For their recruitment, the company had a 5 stage process, one of which was a technical challenge.

Candidates had 5 days to complete the challenge and some never got completed. Also assessment of the technical challenge required DB1 to have a developer present who could verify the answers. The process was slow and inefficient.

DevSkiller automated the technical screening stage of DB1’s recruitment and cut the entire technical test stage from around 5-10 days originally, down to 3-7 days with DevSkiller.

DevSkiller tests are assessed automatically which got rid of the need for DB1 to have a developer present. The experience also improved for the candidates and was much quicker.

Not only did DB1 quicken up their whole technical screening process, they are now more confident that the candidates they do select are the right ones for the job.

 “DevSkiller reduced the time on the technical test stage and reduced our dependence on other areas. It was faster to approve candidates for the next stage since we had an automatic score. Now the revision process is faster, most of the time we have instant results and scores that help us decide which candidate is approved to the next stage of the selection process. Our candidates say it’s a great platform and it really tests their knowledge.”
