Questions and answers

Is .NET still a good choice for new projects?
Yes. .NET remains one of the most robust platforms for enterprise applications, especially after the unification in .NET 8+, which brought performance comparable to the fastest languages on the market. Microsoft keeps annual update cycles (LTS every two years), guaranteeing long-term support and native Azure compatibility.
What is the difference between .NET Framework and modern .NET (.NET Core/.NET 8+)?
.NET Framework is the legacy version, limited to Windows and without performance updates since 2019. Modern .NET (starting with .NET Core, today unified in .NET 8+) is cross-platform, open source, faster and receives continuous updates, which is why .NET Framework systems are natural migration candidates.
Is .NET scalable for large applications?
Yes. .NET supports high-scale architectures, including microservices, asynchronous processing and native integration with Kubernetes and Azure. Companies such as Stack Overflow and Bing run critical infrastructure on .NET, validating its capacity in high-traffic environments.
How much does it cost to hire a .NET development team?
The cost varies with the hiring model: freelancers charge by the hour with no continuity guarantee, while managed squads (such as NextAge's Staff Augmentation) work on a recurring monthly contract, including talent backup and built-in technical management. Managed teams usually have a lower total cost in the medium term because they eliminate turnover and rework.
Is it worth migrating a legacy .NET Framework system to modern .NET?
Yes, when the cost of keeping the legacy system (lack of support, vulnerabilities, low performance) outweighs the cost of migrating. The migration can be done incrementally, without rewriting the system from scratch, reducing operational risk during the process.
Is .NET secure for financial or banking applications?
Yes. .NET offers native security features such as OAuth2/JWT authentication, built-in encryption and compliance with standards like PCI-DSS when implemented correctly. Banks and fintechs use .NET widely for this combination of security and performance.
What is the difference between hiring .NET freelancers and a specialist company?
Freelancers offer point-in-time flexibility, but do not guarantee continuity, technical backup or code review standards. A specialist company delivers managed teams with architects, tech leads and QAs, plus a defined SLA and governance over the quality of the code delivered.
Does .NET work well with a microservices architecture?
Yes. .NET has native microservices support through ASP.NET Core, with direct integration to Docker, Kubernetes and Azure Service Bus for service-to-service communication. It is one of the most used stacks for modernizing monoliths into distributed architectures.
How long does it take to migrate a legacy system to modern .NET?
The timeline varies with the size and complexity of the system, but incremental migrations (module by module, without interrupting operations) usually take 3 to 12 months. Systems with high technical debt first require an architecture diagnosis before the real schedule can be defined.
Is it hard to find .NET developers on the market?
Senior .NET developers are scarce and concentrated in large urban centers, which increases direct hiring time and turnover risk. This is one of the main reasons companies choose specialized outsourcing instead of building in-house teams from scratch.
