Hiring a .NET development company makes sense when your in-house team lacks the capacity, expertise, or time to deliver a critical project in the Microsoft ecosystem. In 2026, this decision has become more urgent: according to Microsoft<\/a>, .NET 8 and .NET 9 will stop receiving security updates and technical support on November 10, 2026.<\/p>\n

For many companies, this means that important systems (portals, APIs, custom ERPs, internal applications) will run without vulnerability fixes after that date. At the same time, the innovation backlog keeps growing, and hiring experienced .NET developers takes months.<\/p>\n

In this article, you will learn the signs that your company needs .NET development services, how to compare the available engagement models, and which criteria to use when choosing a reliable partner.<\/p>\n

\n

Quick answer:<\/strong> it makes sense to hire .NET development services when (1) you have a strategic project with a deadline your in-house team cannot absorb; (2) your systems run on .NET versions that are out of support or about to be; (3) you lack expertise in areas such as legacy migration, Azure, or microservices; and (4) hiring internally would take longer than the business can wait.<\/p>\n<\/blockquote>\n

What are .NET development services?<\/h2>\n

.NET development services cover the creation, modernization, and evolution of software built on .NET, Microsoft’s open-source, cross-platform development platform. In practice, a .NET development company can deliver new web and mobile systems, APIs, integrations, migration of legacy applications to current versions, cloud adoption, and maintenance of systems in production.<\/p>\n

The ecosystem includes technologies such as C#, ASP.NET Core, Blazor, .NET MAUI, and Entity Framework, and integrates natively with Azure, while also running on AWS, Google Cloud, and Linux servers.<\/p>\n

The platform remains highly relevant. In the 2025 Stack Overflow Developer Survey<\/a>, ASP.NET Core was used by 19.7% of respondents, and Azure by 26.3%. In mid-sized and large companies, especially in finance, manufacturing, and services, .NET often powers core business systems.<\/p>\n

When to hire a .NET development company: 8 signs<\/h2>\n

The signs below help technology leaders identify the moment when a specialized partner stops being optional and becomes the safest way to deliver results.<\/p>\n

1. Your systems run on .NET versions that are out of support (or about to be)<\/h3>\n

If your company has applications on .NET 8, .NET 9, or the older .NET Framework, the risk is real. According to the official .NET support policy<\/a>, LTS (Long Term Support) releases receive three years of free support, and STS (Standard Term Support) releases receive two. .NET 8 is an LTS release and .NET 9 is an STS release; both reach end of support on November 10, 2026.<\/p>\n

Microsoft recommends upgrading to .NET 10, an LTS release supported until November 2028. Companies using Azure Functions need to pay extra attention: the in-process model also loses support on the same date<\/a>, and applications must move to the isolated worker model.<\/p>\n

Your system will not stop working the next day, but vulnerabilities discovered after that date will not be patched. For companies subject to audits, data protection laws, or industry regulations, this is a compliance issue, not just a technical one.<\/p>\n

The upgrade itself is rarely the hard part. The effort lies in mapping third-party dependencies, adjusting custom code, reviewing hosting, and ensuring test coverage. This is exactly the kind of project, with a clear beginning, middle, and end, that a dedicated squad with a defined scope and timeline<\/a> can deliver without pulling your team away from day-to-day operations.<\/p>\n

2. You have a strategic project with a deadline, and your team is fully booked<\/h3>\n

This is the most common scenario: the IT team handles maintenance, support tickets, and small improvements, but has no bandwidth for a new project. The result is a growing backlog, stalled innovation initiatives, and business units left waiting.<\/p>\n

Every delayed sprint has a cost: a feature that does not reach customers, a process that stays manual, an opportunity a competitor seizes first.<\/p>\n

When a project has a clear goal and a defined deadline, bringing in a dedicated external team makes more sense than overloading your current staff. In NextAge’s Software Projects service, the squad works under your management: you keep control of project decisions, and NextAge guarantees the technical standard and the delivery SLA.<\/p>\n

3. Your legacy system has become a bottleneck<\/h3>\n

Applications built ten or fifteen years ago on .NET Framework, WebForms, or WCF tend to show the same symptoms: slow performance, manual deployments, difficulty integrating with new systems, and dependence on a few people who understand the code.<\/p>\n

Modernizing these systems brings measurable gains. According to the AWS Brasil blog<\/a>, Thomson Reuters reduced its technical debt by 70% by migrating from .NET Framework to cross-platform .NET. PTT Digital, in Thailand, cut cloud infrastructure costs by 76% and achieved 13 times better performance by moving from .NET Framework 4.8 on Windows to .NET 8 on Linux.<\/p>\n

In most cases, the safest approach is not to rewrite everything from scratch. It is to modernize in stages: breaking features out into services, migrating piece by piece, and keeping the system running throughout the process. That requires planning and hands-on experience with this type of transition.<\/p>\n

4. You lack expertise for a specific need<\/h3>\n

Not every in-house team masters every area of the .NET ecosystem. Microservices architecture, performance optimization, Azure migration, Blazor development, AI model integration, or mobile apps with .NET MAUI are examples of needs that require specific knowledge.<\/p>\n

Hiring a full-time specialist for a one-off project rarely pays off: the process is long, the cost is fixed, and once the project ends, that expertise may not be needed on an ongoing basis. A partner with a multidisciplinary team solves the need with the right profile, for as long as necessary.<\/p>\n

5. Hiring internally will take too long<\/h3>\n

The Brazilian tech market still faces a talent shortage. Data from Brasscom, cited by Abruc<\/a>, shows that between 2019 and 2024 the market demanded 665,000 tech professionals, while higher and technical education produced about 465,000: a gap of 30.2%. The same survey shows that the average salary in the IT and communications sector grew 15% between 2023 and 2025, above the national average of 12%.<\/p>\n

For senior .NET profiles with architecture and modernization experience, competition is even fiercer. If your project cannot wait three to six months for recruiting, onboarding, and ramp-up, bringing in a ready-made team is the fastest alternative.<\/p>\n

This shift also shows up in global research. According to the Deloitte Global Outsourcing Survey 2024<\/a>, cost reduction is no longer the main reason to outsource (it fell from 70% of companies in 2020 to 34%), while 42% now cite access to specialized talent as their top driver.<\/p>\n

6. You need predictable cost and timelines<\/h3>\n

Software projects that start without a clear scope tend to overrun their schedule and budget. Requirements that surface mid-project, poorly defined features, and lack of prioritization are the most frequent causes.<\/p>\n

If leadership expects predictability, your engagement model must deliver it. Look for partners who structure the scope before development starts and commit to delivery terms in the contract.<\/p>\n

At NextAge, every project starts with scope planning: technical challenges are analyzed and the scope is built with features, timelines, and a backlog defined before the first sprint. The mapping is AI-assisted, which speeds up the process without leaving critical requirements behind.<\/p>\n

7. Code quality issues and bugs are delaying releases<\/h3>\n

Constant rework, bugs reaching production, a lack of automated tests, and rushed code reviews are signs that your development process needs reinforcement. Over time, these issues pile up as technical debt and make every new feature more expensive.<\/p>\n

A specialized partner brings established quality practices: dedicated QA, automated testing, and systematic code review. In NextAge’s model, all code goes through AI-assisted code review, and validation is performed with proprietary AI-powered testing, which reduces rework and improves delivery consistency.<\/p>\n

8. You want to use AI in your product or development process<\/h3>\n

Artificial intelligence has changed the way .NET software is built and modernized. Microsoft itself now offers an AI-powered modernization agent with GitHub Copilot<\/a>, which analyzes projects and dependencies and supports migration from .NET Framework to modern versions through assessment, planning, and execution stages.<\/p>\n

Tools, however, do not replace experience. AI-generated code needs review, and architecture decisions still require human judgment. Combining both is what delivers real productivity gains safely.<\/p>\n

That is the idea behind NextFlow AI, NextAge’s methodology that combines AI and human expertise at every stage of development, from requirements gathering to testing.<\/p>\n

In-house team, staff augmentation, or dedicated squad: which model should you choose?<\/h2>\n

There is no single model that fits every situation. The right choice depends on the type of need, the deadline, and your company’s management capacity.<\/p>\n

For projects with a clear scope and deadline, such as an upgrade to .NET 10, a legacy modernization, or the development of a new product, a dedicated squad usually offers the best balance between speed, control, and predictability.<\/p>\n

How to choose a .NET development company: checklist<\/h2>\n

Before signing a contract, evaluate potential partners against the criteria below.<\/p>\n

    \n
  1. Experience with modern .NET and legacy systems.<\/strong> Your partner must know both current versions (.NET 8, 10, and beyond) and .NET Framework, since many projects involve moving between them.<\/li>\n
  2. Verifiable cases and clients.<\/strong> Ask for examples of projects similar to yours, ideally in the same industry, and talk to current clients.<\/li>\n
  3. A structured scoping process.<\/strong> Be wary of proposals that start development without requirements gathering and a defined backlog.<\/li>\n
  4. SLA and metrics in the contract.<\/strong> Deadlines, quality indicators, and responsibilities should be formalized.<\/li>\n
  5. Quality practices.<\/strong> Check for code review, automated testing, dedicated QA, and a CI\/CD pipeline.<\/li>\n
  6. Transparency.<\/strong> You should have access to the code and receive reports on progress, quality, and project health without depending on status meetings.<\/li>\n
  7. Continuity guarantees.<\/strong> Ask how the partner handles team members leaving mid-project. At NextAge, replacement is guaranteed by contract, with no impact on the timeline.<\/li>\n
  8. Responsible use of AI.<\/strong> Understand how the partner uses AI in development and what human controls exist over generated code.<\/li>\n<\/ol>\n

    How long does a .NET project take, and how much does it cost?<\/h2>\n

    There is no single answer, because timelines and investment depend on factors specific to each system. The main ones are:<\/p>\n
