.NET and C# development for enterprise-grade systems
.NET is a cross-platform development platform from Microsoft, and C# is its main language. With ASP.NET Core it is a strong choice for enterprise web applications and APIs, particularly in organisations already using Azure, SQL Server or Microsoft 365.
Modern .NET runs on Windows, Linux and macOS, performs very well and benefits from a strongly typed language, excellent tooling and long-term support releases. It integrates naturally with Azure, Active Directory and SQL Server. The ecosystem leans towards enterprise patterns, which can feel heavy for a small product or start-up. If your organisation has no Microsoft investment and wants to move fast on a simple web product, Laravel, Django or Node.js may be quicker to deliver.
What we build with .NET / C#
- Enterprise web applications with ASP.NET Core
- APIs and microservices
- Integrations with Microsoft 365 and Dynamics 365
- Modernisation of .NET Framework applications
- Background services and scheduled processing
.NET / C# questions
Can you migrate from .NET Framework to modern .NET?
Yes. We assess dependencies, move shared libraries first and migrate the application in stages, so it can run on Linux or containers once complete.
Does .NET have to run on Windows?
No. Modern .NET is cross-platform and runs well on Linux servers and in containers on any major cloud.
What is ASP.NET Core used for?
ASP.NET Core is the web framework within .NET for building APIs, web applications and real-time services. It is fast, cross-platform and well suited to enterprise systems.
Is .NET a good fit for Azure?
Yes. .NET integrates closely with Azure services such as App Service, Functions and Azure SQL, though it runs equally well on other cloud providers and on Linux servers.
How does .NET handle data access?
Entity Framework Core provides an ORM for SQL Server, PostgreSQL, MySQL and other databases, and lighter tools are available where raw SQL performance matters. We choose per workload.
Can .NET integrate with Microsoft 365 and Active Directory?
Yes. .NET has strong support for Microsoft Entra ID and Microsoft 365 APIs, which makes single sign-on and integration with Outlook, Teams and SharePoint straightforward.
How do you test .NET applications?
We use established testing frameworks for unit and integration tests, including in-memory hosting of APIs for realistic endpoint tests. Tests run automatically on every change.
Is C# a good language for long-lived business systems?
Yes. C# is strongly typed, well tooled and backed by a large developer community, which makes large codebases easier to refactor and maintain over many years.
Can .NET build desktop and mobile applications too?
Yes. The .NET ecosystem includes frameworks for Windows desktop and cross-platform mobile and desktop apps, so business logic can be shared with your web backend where it makes sense.
Does .NET have licensing costs?
.NET itself is free and open source. Costs usually come from the hosting, databases or development tools you choose, and we can recommend options that avoid unnecessary licensing.
