.NET / C# Development Services
Square builds .NET systems in C# from Tirana for enterprise and line-of-business software — the stack to choose when you need a statically typed, strongly tooled platform with long-term Microsoft support. We build ASP.NET Core APIs, Entity Framework data layers and background services, and deploy to Azure or your own infrastructure. .NET is our recommendation when the system is large, must integrate with a Microsoft estate, or carries compliance and longevity requirements where C#'s type safety and mature ecosystem pay off. Full CET overlap, fluent English and Italian, EUR 35-55/hour.

What we build
- ASP.NET Core REST and gRPC APIs with strong typing, dependency injection and clean architecture
- Line-of-business and enterprise systems with Entity Framework Core over SQL Server or PostgreSQL
- Background processing and scheduled work with worker services, hosted services and message queues
- Integrations across the Microsoft estate — Azure services, Active Directory/Entra ID, Office and legacy SOAP/REST systems
- Migration and modernization of legacy .NET Framework apps to modern cross-platform .NET
Why this stack
- Choose .NET for large, long-lived enterprise systems where static typing, tooling and Microsoft's support roadmap matter
- Best fit when you already run on Azure, SQL Server or Active Directory — the integration is first-class, not bolted on
- Modern .NET is cross-platform and fast, running in Linux containers with performance that rivals or beats other backends
- Strong typing and a mature framework reduce whole classes of runtime bugs in compliance-sensitive and financial software
- Full CET overlap and EUR 35-55/hour senior engineers, typically 30-60% below comparable Western-European .NET rates
Frequently asked questions
When is .NET the right choice over Node or Python?
Choose .NET for large enterprise and line-of-business systems, anything already in the Microsoft/Azure ecosystem, and compliance-heavy domains where static typing and long-term vendor support reduce risk. Node or Python often win for lean startups, real-time apps or data/ML work — we recommend the honest fit, not a default.Do you work with legacy .NET Framework apps?
Yes. We maintain existing .NET Framework systems and migrate them to modern cross-platform .NET incrementally, so you get Linux/container deployment, better performance and current support without a risky big-bang rewrite.Can .NET run outside Windows and Azure?
Absolutely. Modern .NET is cross-platform — we run it in Linux Docker containers on any cloud or on-prem Kubernetes. Azure makes some integrations smoother, but you're not locked to Microsoft hosting.Do you build the front-end too, or only the .NET backend?
Both. A common pattern is an ASP.NET Core API with a React or Next.js front-end, all delivered by one Square team — so the API contract and the client stay in sync and you have a single point of accountability.
