The success of a company is determined by the skills of its employees. And the IT industry is one of the most innovative fields that bring together some of the best talents in the global economy. 

.NET is one of the most widely used frameworks – approximately 28% of web applications use .NET, according to WhiteHat Security Website Stats. Some of the reasons for its popularity include the fact that it is scalable, and provides a lot of easy to use tools and ready libraries. 

If you are looking to hire a .NET developer, first there are several things you need to know about .NET. 

A productive .NET developer needs to know frameworks and libraries such as MVC, ASP.NET, or Entity Framework. 

But keep in mind that .NET frameworks are often very much alike so if the candidate has significant knowledge of one of them, they can easily understand the other. Even if they are not familiar with the framework or library in your list of requirements, they could still grasp the basic principles and ideas behind it. So do not rule out candidates in case they do not know a framework from your list. 

Remember that experience is what matters and brings real value. If you are hiring a junior .NET developer, you can look for an education degree, but otherwise take into account the experience, not the education. Look for projects that were executed in .NET technology even as a hobby. 

After you have posted your job opening and start receiving resumes and applications, it is time to decide which of the candidates are good enough to proceed to a technical interview. You need to make sure that your hiring team spends time only with the best prospects who have the desired skills and expertise to meet the requirements of the job. But at the same time, it is important not to miss a good candidate who might have the right skills but not the best resume. 

In order to get all the candidates that meet the requirements of the job, you need to screen their .NET programming skills. Here are the best tools you can use to verify .NET developers in the screening process. 

If you are looking for online assessment tests, you may want to consider some of the following options:
