Meta Description: Compare the top .NET development company Ukraine options for 2026: ASP.NET Core, Azure, Blazor and .NET MAUI teams, plus tips for hiring C# developers.

Choosing a .NET development company in Ukraine is a different decision from choosing a general outsourcing vendor. Most Ukrainian firms list .NET somewhere on their technology page, but far fewer run a real C# practice with senior engineers, current ASP.NET Core and Azure experience, and a track record of moving old .NET Framework systems onto supported runtimes. This guide focuses on that smaller group.

Every company below shows a clear .NET or C# offering on its own website, along with a Ukrainian headquarters or a real Ukrainian engineering office. Where a firm states Microsoft partner status, we note it; where it does not, we leave it out. Specialists come first, and larger generalists appear where their Microsoft credentials or scale justify a place.

Ukraine remains one of the deepest pools of C# developers in Europe, and many firms have added offices in Poland or elsewhere in the EU to give clients extra continuity. If you want a wider view of the market, our list of software development companies in Ukraine covers the full range of stacks, and our comparison of Poland, Ukraine and Romania for nearshore work helps if you are still deciding on a country.

Best .NET Development Company Ukraine Options In 2026

1. Blackthorn Vision — Microsoft Solutions Partner Since 2009, Engineering Out Of Lviv

Blackthorn Vision is the most clearly Microsoft-focused firm on this list. Its .NET development page describes the company as an official Microsoft Solutions Partner since 2009, and the About page says the team has been helping healthcare, fintech, energy and B2B software companies design, modernize and scale products for more than 16 years. The stack it names is specific: ASP.NET Core, Blazor, .NET MAUI and Entity Framework Core, deployed on Azure or AWS. The company reports more than 50 completed .NET projects and more than 150 long-term projects overall, with engineering based at its Lviv office on Kulparkivska Street and additional offices in Warsaw and Wroclaw.

The practical draw for buyers is the mix of new builds and modernization. Blackthorn Vision lists API integration, microservices, desktop applications, cloud-native work and legacy modernization under its .NET services, and it highlights an event registration platform built on .NET Core and Azure for a Fortune 500 client that handles millions of records. The site also says 75% of the team are senior or middle-level engineers and that the average client engagement runs beyond five years, which suggests the firm is set up for long product relationships rather than short one-off builds. It is a strong first call for a product company that wants a partner comfortable across the whole Microsoft ecosystem, from Azure architecture to AI features layered onto an existing .NET application.

2. Devspiration — Microsoft Stack Specialist For Fintech And Insurance Since 2008

Devspiration builds almost everything on the Microsoft stack, and says so plainly: its homepage describes .NET as the company’s main technical stack and presents the firm as a Microsoft Certified Partner. Founded in 2008, it reports more than 170 professionals and more than 50 completed projects, with its office at 108 Stryiska Street in Lviv and a US address in Scotts Valley, California. The .NET page covers .NET Core, ASP.NET Core for high-traffic web applications, the classic .NET Framework, WPF for desktop interfaces and Azure for cloud work, with Blazor also listed in the technology menu.

Where Devspiration stands out is legacy work in regulated industries. Its service list includes migration to .NET Core, modernization of existing .NET software and Azure migration, which is exactly the job many banks and insurers face with aging line-of-business systems. The company lists banking, fintech, insurance, e-commerce, healthcare and energy among its sectors and is a member of the Ukrainian Association of FinTech and Innovation Companies. It also runs business intelligence and data engineering practices, so a buyer can pair a .NET rebuild with reporting and data pipeline work under one contract. The site says most of its .NET programmers are senior or middle-level specialists, which fits teams that need people who can read old code, not just write new code.

3. Exoft — Blazor, SignalR And .NET MAUI Teams From Lviv

Exoft is a Lviv software company that has been working since 2013 from its office on T. Shevchenko Street. Its dedicated page for hiring .NET developers is one of the more detailed in the market: it lists C#, ASP.NET, ASP.NET Core, Blazor, MVC and SignalR, plus .NET MAUI (formerly Xamarin.Forms) for cross-platform mobile, with deployment on Azure, AWS or Google Cloud. The team describes experience across the full Microsoft ecosystem and support for multi-tier, microservices and cloud-native architectures built on containers and serverless components.

Exoft offers three ways to work: staff augmentation on a full-time, part-time or ad hoc basis, a dedicated .NET team, or managed services where Exoft forms the team and runs the workflow. Its .NET case examples are practical ones: HIPAA-compliant patient feedback software written in C# and ASP.NET MVC, a fitness platform migrated to .NET 8, and an assistive listening system portal rebuilt on the .NET stack. The About page cites more than 500 delivered projects and a 95% customer satisfaction rate. Industries include healthcare, logistics, finance, energy, construction and education. For a buyer who wants to hire .NET developers in Ukraine and keep them inside an existing Scrum team, Exoft is a sensible fit.

4. Chudovo — German-Managed .NET Shop With A Kyiv Delivery Office

Chudovo combines a German head office in Castrop-Rauxel with a development office on Sholudenka Street in Kyiv. It has been on the market since 2006 and lists more than 40 full-time experts and more than 190 implemented projects. Its .NET page claims more than 50 cross-industry .NET projects and covers an unusually wide slice of the platform: ASP.NET Core for web, .NET MAUI and Xamarin for mobile, and WPF, Avalonia UI and Blazor Hybrid for desktop, with C#, F# and C++ in the language list.

That desktop depth is the reason to shortlist Chudovo. Many .NET buyers are not building a new SaaS product but maintaining a WPF or WinForms tool that runs a factory, a lab or a trading desk, and Chudovo’s page speaks directly to desktop solutions and legacy system modernization alongside Azure, AWS and Google Cloud deployment. The company offers team augmentation, dedicated teams and full project outsourcing, and it publishes indicative hourly rates on its .NET page, starting around $20 for junior developers and reaching about $60 for architects. Industries on the homepage include healthcare, fintech, retail, telecom, manufacturing and logistics. German management with a Ukrainian engineering team suits clients in the DACH region who want contracts and communication handled close to home.

5. Abto Software — Microsoft Solutions Partner With 200+ .NET Projects

Abto Software was launched in 2007 and reports more than 280 IT specialists and more than 250 customers. Its .NET development page presents the firm as a Microsoft Solutions Partner with more than 200 .NET projects behind it, and it names ASP.NET Core, Entity Framework Core, WCF and WPF on the backend, Azure and AWS in the cloud, and Docker, Kubernetes and Azure DevOps for delivery. Abto’s current contact addresses are in New York and Nicosia, while its engineering roots are in Lviv: the company is a long-time member of the Lviv IT Cluster, its news archive describes its Lviv office and R&D lab, and client reviews on its .NET page mention building a dedicated team in Lviv with Abto.

The service mix leans toward large, older systems. Abto lists legacy modernization and migration, Azure cloud development for IaaS, PaaS and SaaS products, and migration from monoliths to microservices, alongside AI-based analytics added to existing applications. Its engagement options are full-cycle development or a dedicated team, and the page states it can grow a team quickly, up to 100 engineers. Industries include healthcare and life sciences, manufacturing, construction and real estate, telecom, government and fintech. Abto is a good fit for an enterprise that has a large .NET estate and wants one vendor able to staff a multi-year modernization program.

6. IT Hoot — .NET Core, Orleans And Angular From Khmelnytskyi

IT Hoot is a smaller, .NET-first shop based in Khmelnytskyi in western Ukraine, with a second office in Tallinn, Estonia. The company lists 51 full-time developers and says it has more than 15 years in IT development. Its backend stack is heavily Microsoft: .NET Core, Entity Framework, Microsoft Orleans, microservices and serverless patterns on Azure or AWS, with MS SQL, PostgreSQL, MySQL and Redis on the data side. On the frontend it pairs .NET MVC with Angular, TypeScript and Material UI.

The Orleans mention is worth noting, because the actor framework is a niche skill that appears in few vendor stacks and matters for real-time or high-concurrency systems. IT Hoot structures projects in four phases, discovery, visualization, development and launch with support, and also offers staff augmentation and a re-engineering service for existing applications. Two points on the site help buyers set expectations: the company says it does not bring in third-party developers, and it cites an average project size of around $50,000. Portfolio examples include e-commerce platforms and booking tools. That profile suits startups and mid-size companies that want a compact .NET and Angular team outside the Kyiv and Lviv hubs.

7. Waverley Software — Silicon Valley Firm Porting Legacy Apps To .NET Core From Lviv

Waverley Software was founded in Palo Alto in 1992 and now reports more than 300 specialists across three continents, with a Ukrainian engineering office on Brativ Mikhnovskykh Street in Lviv alongside centers in Poland and Bolivia. Its .NET practice page covers C#, ASP.NET Core, .NET 5.0 and later, Entity Framework, Microsoft Azure, Docker and Kubernetes, and it offers .NET work from architecture and roadmap through release and support.

The legacy angle is explicit. Waverley says it will modernize existing applications or port them to .NET Core and that it handles legacy projects of any scale, which is useful for buyers sitting on .NET Framework 4.x code that needs to move to a supported runtime. It also lists cloud migration and microservices design. For compliance-heavy clients, the page mentions ISO 27001 certified development offices and experience with GDPR, CCPA, SOC 2 and HIPAA requirements. Engagement models include dedicated teams in Eastern Europe or Latin America, staff augmentation and end-to-end outsourcing. A US company that wants a Silicon Valley contract, time zone overlap options and Ukrainian .NET engineers on the same account will find that combination here.

8. Devabit — ASP.NET Core, Blazor And MAUI Teams With Published Ukraine Rates

Devabit is a Lviv company, with its office on Zelena Street and a US address in Brooklyn, New York. It runs dedicated .NET consulting and hire-a-developer pages, and the technology coverage is current: ASP.NET Core, Blazor, .NET MAUI and Azure, plus support for migrating legacy .NET Framework applications. The services are grouped into four lines: .NET application development for web, desktop and mobile; migration and modernization; integration with existing and third-party systems; and ongoing support and maintenance.

Devabit is one of the few firms that publishes its Ukrainian rate bands on the page, listing junior .NET developers at $20 to $35 per hour, mid-level at $35 to $50 and senior at $50 to $80 or more. It says a project can start within two to four weeks and offers dedicated team, time and material, and fixed cost engagements. The company reports more than 80 end-to-end projects and says 97% of customers are willing to refer it. That transparency helps procurement teams that want to budget a C# team before the first call, and the fixed cost option suits well-defined migration or integration jobs.

9. Brainence — Lviv .NET Team And Certified Linnworks Partner

Brainence is a bespoke software company based on Lemkivska Street in Lviv, with a London office for client relationships. It has been operating since 2016, and its .NET development page lists ASP.NET Core, Blazor and .NET MAUI, with Microsoft Azure, AWS and Google Cloud for hosting. Services cover custom .NET development for web, mobile and desktop, migration to modern .NET with minimal downtime, maintenance and support, and consulting on implementation choices.

The e-commerce specialization is what sets Brainence apart. The company is a certified Linnworks partner and its recent work includes the Replyco e-commerce platform, a data collection platform, and the WellCru healthcare product. For online retailers and marketplace sellers that need custom .NET services wired into order management, inventory or shipping tools, that background shortens the learning curve. Brainence describes an Agile and Scrum-based process and says it builds with encryption, secure authentication and GDPR and HIPAA requirements in mind. It is a good match for UK and European buyers who want a smaller Lviv team with a London point of contact.

10. CyberCraft — 30+ .NET Developers And 3.5-Year Average Partnerships

CyberCraft is a full-cycle custom software company in Lviv, founded in 2012, with more than 100 people on board and client-facing phone lines in the US and Poland. Its .NET page gives concrete numbers: more than 30 .NET developers with an average of four years of professional experience, senior engineers with six to eight years, and more than 20 .NET projects delivered since 2012. The stack centers on ASP.NET Core and Azure cloud services.

The company’s .NET services include custom development, .NET web development, full-cycle outsourcing, team augmentation, integration and optimization, maintenance and support, and consulting. Case studies on the site include governance and compliance platforms, marketplaces and enterprise resource tools, and industries named on the .NET page are e-commerce, real estate, e-learning and healthcare. The most telling figure for buyers is retention: CyberCraft reports an average partnership length of more than 3.5 years and more than 150 successful projects overall. That points to a firm used to long, steady engagements, which is what most small and mid-size businesses want from an ASP.NET development partner in Ukraine.

11. Softengi — Kyiv-Rooted Microsoft Partner And Cloud Solution Provider

Softengi is the largest generalist on this list and earns its place through Microsoft credentials and enterprise delivery. The company was established in 2009 as a spin-off from Softline-IT, whose history goes back to 1995, and reports more than 300 specialists and more than 2,000 completed projects. Its Ukrainian office is in Kyiv, with further offices in Poland, Italy, the UAE and the US. The About page says Softengi became an official Microsoft Partner and Cloud Solution Provider in 2025, and its expertise page lists C#, .NET and ASP.NET among its languages and frameworks, with Azure as a cloud platform.

Softengi is not a .NET boutique, and buyers should treat it as a broad engineering vendor. That breadth is the point for some programs: the company also runs IoT, extended reality, AI, SAP integration and enterprise application practices, and it holds ISO 9001, ISO/IEC 27001 and ISO/IEC 42001 certifications. It has appeared on the IAOP Global Outsourcing 100 list for the tenth time in 2025. On continuity, the About page says the company adopted a resilient approach in 2022 that kept projects running for existing clients. Softengi fits enterprises where a .NET application is one part of a larger system that includes devices, data and cloud licensing.

12. inVerita — Healthcare Platforms On .NET 8, Headquartered In Lviv

inVerita is headquartered in Lviv, with regional offices in Kyiv, Krakow, San Francisco and Medellin, and reports more than 120 engineers. The company works across several stacks, but its .NET use shows up clearly in its healthcare case studies: an internal clinic management system built on .NET Core, and a four-in-one healthcare platform built with C# and .NET 8. The site also lists .NET web application, e-commerce, CMS and portal development, and offers Azure DevOps services.

Healthcare is where inVerita concentrates, covering telemedicine, hospital management, EHR and EMR systems, pharma and medical devices, with fintech, banking and logistics as secondary verticals. That makes it a sound option for a health tech company that needs a .NET backend built with regulated data in mind and may also want mobile apps, AI features or a dedicated team on the same contract. Buyers who need deep, .NET-only specialization will find stronger fits higher on this list, but for .NET projects inside healthcare, inVerita brings domain knowledge that a generalist C# vendor would not.

How To Choose A .NET Development Company In Ukraine

Does the vendor run a real .NET practice or just list it?

Start with the company’s own .NET page. A firm with a genuine practice names specific frameworks such as ASP.NET Core, Entity Framework Core, Blazor, WPF or .NET MAUI, shows .NET case studies, and can tell you how many C# developers it employs. A single .NET logo in a long technology grid usually means the firm can staff a project, not that it has built its business around the platform.

Ask for two or three recent .NET projects similar to yours, the runtime version they targeted, and whether the same engineers are still available.

How much do .NET developers in Ukraine cost?

Rates vary with seniority, team size and contract model, but some firms publish ranges. Devabit, for example, lists junior .NET developers at $20 to $35 per hour and senior developers at $50 to $80 or more, and Chudovo publishes a similar band from junior to architect. Treat these as starting points and compare total cost, including project management, QA and DevOps, rather than developer rates alone.

Can they migrate legacy .NET Framework applications?

Migration from .NET Framework 4.x to modern .NET is one of the most common reasons buyers look for C# developers in Ukraine. Ask how the vendor handles incompatible libraries, WCF services, Web Forms pages and Windows-only dependencies, and whether it plans an incremental migration or a rewrite. Firms such as Devspiration, Waverley Software and Abto Software describe migration and modernization as a core service, which is a good sign that they have done it before.

Is Microsoft partner status important?

It helps, but it is not decisive. Partner status shows that a company has invested in Microsoft certifications and has access to Microsoft programs, which can matter for Azure credits, licensing or enterprise procurement rules. It does not guarantee that the engineers assigned to your project are senior. Check the claim on the vendor’s own site, then judge the team on its interviews and code samples.

Which engagement model fits a .NET project?

For a long-running product, a dedicated team or staff augmentation usually works best, because .NET codebases reward engineers who stay and learn the domain. For a well-scoped migration, integration or proof of concept, fixed price can be cleaner. If you mostly need extra capacity, our guide to dedicated development team providers in Ukraine covers firms that specialize in that model.

Do they cover cross-platform and mobile .NET work?

If you need mobile or desktop apps from a shared C# codebase, confirm hands-on .NET MAUI experience, and ask whether the team has moved any Xamarin.Forms apps to MAUI. Several firms here, including Exoft, Chudovo, Devabit and Brainence, list MAUI on their .NET pages. For a wider field of specialists, see our list of .NET MAUI development companies.

How do Ukrainian vendors handle business continuity?

Ask directly. Many Ukrainian firms now run distributed teams, backup power and internet in offices, and delivery centers in Poland or other EU countries. Request a written continuity plan, confirm where your engineers are located, and check how the vendor handles handover if a team member becomes unavailable. A vendor that answers these questions openly is usually one that has already planned for them.

Conclusion

The right .NET development company in Ukraine depends on what you are building and what you already own. Teams with a large legacy estate should favor firms that describe .NET Framework migration and modernization in detail, while product companies starting fresh should look for current ASP.NET Core, Blazor and Azure experience and a delivery model that keeps senior C# engineers on the account.

Shortlist two or three firms from this guide, ask each for a comparable .NET case study and a sample team, and run a short paid discovery phase before committing to a long engagement.
