.NET Development

A platform built for systems that have to keep running

Most of the .NET work that reaches us falls into one of two camps: a new service that needs to be fast, typed and cheap to operate, or an older application that still earns money but has become expensive to change. Modern .NET handles both well, which is a large part of why it keeps showing up in finance, logistics, healthcare and industrial software long after the “Microsoft-only” reputation stopped being true.

Since .NET Core merged the framework into one cross-platform runtime, the same codebase runs on Linux containers, Windows servers and ARM hardware. In practice that means hosting choices stay open, container images stay small, and the per-instance cost of running an API is low enough that scaling stops being the first thing on the budget.

What we build with ASP.NET Core

• HTTP and gRPC APIs — the workhorse: REST services behind a gateway, or gRPC where two internal services talk to each other often enough that payload size matters.
• Background and scheduled processing — queue consumers, import and reconciliation jobs, and the long-running workers that batch work overnight.
• Line-of-business web applications — internal tools, admin panels and operational dashboards, either server-rendered or paired with a separate frontend.
• Integration layers — the code that sits between an ERP, a payment provider and three systems that were never designed to speak to each other.

Bringing older .NET applications forward

A large amount of working software is still on .NET Framework 4.x, where support is tied to the Windows version underneath it and hiring gets harder every year. We treat that as an incremental job rather than a rewrite: inventory the dependencies that actually block a move, replace the ones with no modern equivalent, port project files, and migrate a slice at a time behind a facade so the application keeps shipping throughout.

The honest version is that some of these migrations are not worth doing. If an application is stable, rarely changed and not blocking anything, saying so is more useful than quoting a rewrite.

The stack we work in

ASP.NET Core and minimal APIs, Entity Framework Core and Dapper for data access, xUnit and Testcontainers for tests that hit a real database, SQL Server and PostgreSQL, Redis for caching, RabbitMQ or Azure Service Bus for messaging, and Docker with GitHub Actions or Azure DevOps for delivery. On the client side, Blazor where a .NET-only team is an advantage, and React or Vue where the frontend deserves its own toolchain.

Working with our .NET engineers

You can bring us in to build and own a service end to end, or place .NET engineers inside your existing team through outstaffing when the roadmap is clear and the constraint is capacity. Either way delivery runs the way described on our agile delivery page, and the practicalities of time zones and handover live on the remote development page.
