.NET and C# development

.NET is the right choice when a system carries strict business rules, high transaction volume and has to coexist with existing Microsoft infrastructure. We build services on ASP.NET Core 8 and modernise applications written for .NET Framework.

Where we use .NET

• Financial and billing systems, where correctness matters more than delivery speed.

• Backends for applications with steady traffic and predictable performance requirements.

• Integrations with SQL Server, Active Directory, Microsoft 365 and Dynamics 365.

• Background services: imports, synchronisation, scheduled processing.

• Public partner APIs, with versioning and OpenAPI documentation.

Modernising .NET Framework applications

Many companies still run applications on .NET Framework 4.x, with maintenance costs that keep rising. We approach migration module by module: isolate the business logic, add tests, then move components onto .NET 8 while the application stays in production throughout.

Architecture

We prefer a well-structured monolith until volume genuinely justifies microservices. When they are justified, we use asynchronous messaging, versioned contracts and observability from day one rather than bolted on later.

Cloud

We run on Azure App Service, Azure Container Apps or Kubernetes, depending on the need. For clients with data residency requirements we configure regions inside the European Union or the United States.
