Finding the right .NET developer is harder than it should be. Although ASP.NET Core ranks as the second most-used web framework after Node.js, used by about 19.7% of developers, companies are facing an ever-growing talent shortage. Furthermore, evaluating the qualities of exceptional .NET candidates can be extremely difficult.

For instance, even when presented with a perfect resume, how do you assess the candidate’s ability to receive constructive feedback? What about their level of expertise in ASP.NET Core, .NET MAUI, or Blazor?

Despite all the challenges you may have faced before, the good news is that you can use proven best practices on how to hire .NET developers from start to finish. In this guide, we’ll talk about what a .NET developer does, the skills and seniority levels to look for, how to interview and evaluate candidates, where to find them, and what they cost in 2026. So, let’s get started!

 

What does a .NET developer do?

A .NET developer builds and maintains software on Microsoft’s .NET platform, most often using C#. They write backend services, build web and desktop applications, design APIs, and connect everything to databases and cloud services. In short, they turn your product requirements into working, secure software.

What exactly is a .NET developer, though? Who are they, and what do they do? Plenty of people doing the hiring aren’t sure either. The term .NET refers to the modern cross-platform framework developed by Microsoft, initially introduced as .NET Core in 2016 and later unified as .NET. A few things are worth knowing about .NET:

01
It is more than a package or language; it is a full development platform.
02
When .NET launched it supported several languages, and today its primary language is C#, alongside F# and Visual Basic.
03
.NET is an object-oriented platform.
04
It offers strong security, with advanced encryption and authentication built in alongside modular development practices.
05
It runs on multiple operating systems, including Windows, macOS, Linux, and their server editions.

It’s clear that .NET and ASP.NET Core technology hold much potential for IT. The framework speeds up the development of web, desktop, mobile, and cloud software, and gives teams a secure way to build digital products. Plenty of platforms you know run on it, including Microsoft, GoDaddy, Stack Overflow, and Dell.

The ideal .NET developer to hire would be familiar with .NET 10, ASP.NET Core, Blazor, .NET MAUI, and other modern .NET stacks. A strong .NET developer brings extensive experience in .NET development, which improves productivity. They specialize in building reliable software, applications, interfaces, and integrations.

Why are good .NET developers hard to find?

First, it helps to get to the root cause of the .NET talent shortage. Many theories are flying around regarding why finding the right .NET or ASP.NET Core coder is a hassle. DOIT noted several contributing factors based on its experience staffing .NET developers, and here’s a look at the most prevalent.

 

1. An unclear definition of the role

To determine the level of skill a .NET developer must hold to complete your team, elaborate on what tasks the project involves. You might end up realizing that more developers than you first thought do indeed meet your requirements. The job description matters here.

Given the vast amount of skills relevant to .NET technology, it’s nearly impossible for one person to know all there is to it. As you may have noticed by now, finding the right .NET professional could be easily solved by a clear job description. Being open about what qualifies as experience for a .NET developer will also make a difference.

It’s also worth remembering that graduate developers are often overlooked. While most educational programs do not concentrate much on .NET development, leaving school without such qualifications doesn’t mean fresh graduates have no experience at all. Plenty of students go the extra mile to work on external projects that provide the needed .NET development experience, such as internships and private courses.

 

2. Inefficient hiring processes

How is your hiring process structured? Can you effectively identify competent developers before moving on to onboarding them? Answering these questions can save you both time and money. Be aware of possible cracks in your hiring processes.

If your access is limited to a small pool of developers who meet your criteria, it will severely affect the success of your talent search. You may end up having to hire someone who is not up to the task simply because there are no better-qualified candidates. Additionally, you may have to pay high compensation for your next .NET developer due to scarcity and high demand for programmers.

Consider engaging an IT partner to extend your pool of .NET developers. Outstaffing services will help you fill the vacancies on your team with the right people. With a partner like DOIT Software, you won’t just be looking at an increase in quantity. It’s an increase in quality as well, as we connect you to reputable and experienced professionals.

The hiring process must be short and precise, leaving little margin for error. According to statistics, the average hire time for a .NET developer is 14 days. The faster you are able to hire .NET talent, the easier it will be to complete your project and meet your set deadlines. Employing the help of an IT staffing partner will enable you to speed up the hiring process, thanks to a readily available database of vetted candidates and assistance with interviewing and, in our case, onboarding as well.

Another difficult area is how to evaluate .NET developer skills. Refining and optimizing your hiring processes to adapt to the industry standards will plug this crack in the system. Your candidate evaluation should combine a technical interview with soft-skill analysis and hands-on test tasks. Make sure the people running the technical interview know what skills the role requires. A few workarounds that can speed things up include:

  • Using a well-structured technical interview and test tasks that show a candidate's strengths and weaknesses
  • Engaging seasoned recruiters for easy access to readily vetted candidates
  • Opt for staff augmentation with the right provider, where you can both hire ASP.NET Core coders and the general .NET developers from a large pool

The last option sets you up for interviews almost immediately with top-notch professionals who have the right skills. It also outsources the bulk of the recruitment stages to the staff augmentation service provider, thus, saving you time and money.

What to look for when you hire .NET developers

Now that we have already covered what .NET developers are, let’s get into the technicalities of finding your perfect fit.

If you recall earlier, we divulged in detail the programming skills necessary to fill in different .NET developer posts. Note that the indicated skills do not necessarily make the essential list. The technical abilities to consider when you hire .NET developers are as follows:

1
.NET 10 and recent versions
2
ASP.NET Core
3
Signal R

On top of those, look for candidates with a good grasp of:

  • Object-oriented programming concepts
  • .NET programming concepts
  • Unified .NET development across platforms
  • Blazor or Razor Pages for UI design

Candidates can also share portfolios you can go through, and some have projects on public repositories like GitHub, which helps when you assess technical ability. To avoid hiring someone not up to the task, ask about their experience, then check and verify it in practice where possible.

One note on currency: the current long-term support release is .NET 10, and .NET 8 is still supported through late 2026, so candidates working on either are on solid ground.

 

Using a .NET certificate for professional programming skills evaluation

Certain experts believe .NET certificates are an adequate measure of skill. But not everyone holds this view. To other recruiters, when you hire a .NET developer, professional exams don’t add much weight, because they do not show practical experience.

Developers without experience often take these exams to increase their appeal. When looking for a .NET developer, keep in mind that there are capable developers who will not have certificates. They may be unwilling to sit the exam because they already have ample experience. To sum it up, commercial experience is the most appropriate measure of skill, and a certificate shouldn’t be the deciding qualification.

For example, popular .NET certifications like Microsoft Certified Technology Specialist (MCTS) and Microsoft Certified Solutions Developer (MCSD) are now legacy, which Microsoft retired to align its lineup with newer technologies. But you can still keep an eye on some valuable Microsoft Applied Skills and Certifications related to .NET technology when choosing.

 

Critical soft skills for .NET developers

Soft skills will determine how well a developer works as a team member. A strong set of soft skills includes:

  • Efficient time management
  • Adaptability
  • Ability to plan ahead and fix errors
  • Strong communication skills
  • A good level of spoken English
  • Analytical mindset
  • A desire for continuous self-improvement
  • Trustworthiness

Critical soft skills

The above are useful when drafting the job description. Use the list only as a guide, though. Disregarding candidates who don’t qualify for every requirement isn’t a smart approach.

How to interview a .NET developer

Apart from resumes and programming tests, interviews also contribute to informed hiring decisions. Recruiters use face-to-face interviews to assess a candidate’s character and fit. The interviewers should also be aware of which technologies will apply during development. Placing a senior developer on the interview panel helps, since they will ask the right questions and gauge how well the candidate fits the team.

If meeting in person is not possible, an interview via video call may also suffice. There’s more to be learned by putting a face to the name, since non-verbal cues reveal things about a candidate’s personality that a resume won’t. Your interview should center on the following areas:

  • Their grip on algorithmic concepts
  • How well they think
  • If they have a profound knowledge of database technology
  • Their approach to modeling
  • How they stay informed on the latest trends
  • Their favorite technical resources, e.g. books, websites, journals, social media
  • Their activity on Github
  • Whether they contribute to open source projects or hackathons

Interview questions should establish whether the candidate fits with the existing team, and technical terms are useful indicators of a candidate’s knowledge. When hiring a senior developer, ask both computer-science and role-specific questions. For a ready-made set you can run with, our list of .NET interview questions covers technical and role-specific questions by level.

 

Technical interview

You can’t effectively measure someone’s skill level using the resume alone. This is where tests come in handy. Put together a programming test to check technical proficiency. You can rely on online resources for this and use the C# and .NET programming tests available to pre-screen candidates.

Another useful approach is a test based on a use case from your company, which is much closer to the conditions a developer will face on the job. Aside from programming skills, such tests help hiring managers verify a candidate’s efficiency, for instance, whether they avoid wasting time during development. DOIT evaluates every candidate with a test task to confirm technical proficiency and includes a pre-interview video recording with each profile so the hiring team sees the developer in action first.

The glossary table below explains what testing for each core element covers, so you can read a candidate’s listed skills with a clear idea of what each one means.

Where to find .NET developers

Now that you know how to hire a .NET developer, where do you start your search? Let’s find out.

 

In-house hiring

You can grow your developer team by hiring in-house employees. Your HR department advertises vacancies to attract seasoned professionals on job boards, job sites, developer communities, and social media. From there, you vet and interview the top candidates to find the most suitable people to hire. In-house hiring will, however, require you to spend more time and money on recruitment, since there are usually no readily available candidates.

 

Hiring freelance .NET developers

Aside from taking on .NET developers as full-time employees, you can also hire them as freelancers. To hire freelance .NET developers, companies first scout for suitable collaborators, then trace references to verify work history and conduct interviews.

Although freelancers work on a temporary basis, the recruitment process needs as much time and effort as hiring in-house. Verifying a candidate’s technical skill level is a common challenge, so skills evaluation still requires companies to run technical interviews and test tasks themselves.

 

Make use of job sites

For small projects, you can hire a freelance ASP.NET Core developer. Some of the best sites for hiring .NET developers include platforms like Upwork and Freelancer. It is a low-cost approach that also helps you get the work done quickly. You will, however, need to read the reviews carefully to make sure the developer you hire is truly up to the task

 

Explore online dev communities

Another good place to find .NET developers is online communities. Many .NET coders with ample experience frequent such places. You can post your open positions on job boards for dev communities on sites like Stack Overflow and GitHub.

 

Staff augmentation services

A staff augmentation company immediately puts you in touch with qualified professionals. It is a cost-saving way to fill a talent gap, and a practical option when you want to hire remote .NET developers without a long-term commitment. You get to expand your existing development team to meet the requirements of your project. As an IT partner, DOIT can help you fill .NET developer roles with the talent you need.

High recruitment costs

How much does it cost to hire a .NET developer?

In 2026, the average .NET developer salary in the US runs roughly $112,000 to $133,000 a year, based on figures from salary trackers like Glassdoor and ZipRecruiter, with senior developers at the top of that range. The US is one of the most expensive places to hire, so to bring on the top 5% of .NET coders without overspending, you may want to look at nearshoring or offshoring.

Note that these figures only account for the salaries developers receive. To find the full cost to the business, add about 30% to each figure as an estimate for administration expenses and related taxes. Here are the salaries you can expect to pay .NET developers by region.

Common mistakes to avoid when hiring .NET developers

A few mistakes come up again and again when hiring .NET developers, and most of them happen early, while you are writing the job post or running interviews. Each one is easy to avoid once you know about it.
01
Not saying which kind of .NET work you need
As we mentioned at the start of the article, ".NET developer" covers very different jobs. Building the backend of a website, building a desktop app, running a cloud service, and keeping an older system going each need different experience. Say which one you need in the job post, along with how senior the person should be, and the people who apply will fit much better.
02
Mixing up the old and new .NET
There are two versions of .NET in use: the older .NET Framework and the modern .NET. Someone who knows one well does not always know the other. Decide early whether you are keeping an older system running or building something new, and look for the matching experience, so the developer is up to speed sooner.
03
Picking the wrong level for the work
A very senior developer on simple, repetitive work means paying senior rates for basic output, while a junior put in charge of designing a whole system can create problems that surface later. Match the level in the seniority table above to the work the role really involves, and treat that match as more important than an impressive CV.
04
Forgetting that communication matters
We listed communication among the soft skills earlier, and it is worth saying again here. A .NET developer joins a team and an existing codebase, so someone who explains their decisions, follows the brief, writes clear updates, and flags problems early saves everyone time. Good spoken and written English counts as much as technical skill, especially when the team is remote.
05
Choosing on price alone
The lowest hourly rate is rarely the cheapest in the end. Once you add the cost of fixing mistakes and replacing people who leave, a mid-priced developer who gets it right the first time often works out cheaper than a low-priced one who needs constant checking.
06
Not having a backup plan
Even a careful hire can turn out to be the wrong fit, so plan for that from the start. If you hire in-house, stay in touch with your two strongest runner-up candidates while the new developer works through a probation period, and ask the new hire to document their work as they go, so nothing is lost if they move on.

If you go through a staffing partner, agree up front what happens if it does not work out, so a poor match costs you a few days at most. DOIT covers this with a replacement guarantee and help handing over the work, so you are never left starting from scratch.

Start building your .NET team

Knowing how to hire .NET developers does not have to be complicated, and you can do it without breaking a sweat. Position your company to tap into the vast talent pool accessible through the various approaches mentioned above. Whether the most beneficial arrangement is through freelance platforms, online developer communities, or, better yet, IT partners like DOIT, the hiring process can be largely simplified.

Refine your internal recruitment by using face-to-face interviews and test tasks, and take a modern stance toward evaluating .NET developer qualifications. You could never go wrong building your team this way. If you don’t want to go through the dreaded hunt for the right .NET developer, finding the right staffing partner who knows the ins and outs of the industry, like DOIT Software, is your best shot.

How long does it take to hire a .NET developer?

It depends on the route. An in-house search can run from a few weeks to a couple of months, and the average time to hire sits around two weeks of active interviewing. A staff augmentation partner is faster: DOIT, for instance, sends the first pre-screened profiles within 3-5 business days for common stacks, so most of the wait is your own review time.

What would be the estimated cost of hiring .NET developers?

In 2026, US salaries average roughly $112,000 to $133,000 a year, with senior developers at the higher end. Eastern Europe offers comparable skill for noticeably less, at about $36,000 for a junior and $54,800 for a senior. Remember to add about 30% to any salary figure for taxes and administration, unless you hire through a partner that already covers those costs in the rate.

Are .NET developers in demand?

Yes. In the 2025 Stack Overflow Developer Survey, ASP.NET Core ranked as the second most used web framework after Node.js, used by about 19.7% of developers. C# and .NET remain a core choice for enterprise, web, cloud, and desktop software, so demand for skilled developers stays high.

Should you hire .NET developers in-house, freelance, or through staff augmentation?

In-house suits long-term core roles you want full control over. Freelancers fit small, one-off tasks. Staff augmentation works best when you need vetted mid or senior developers quickly and want to scale up or down without a long-term commitment. Match the model to how long the work runs and how fast you need someone.
