.NET development services
Typed, quick, and supported on a published schedule your auditor can read.
We build and maintain .NET systems: ASP.NET Core APIs, Blazor and MVC applications, background workers, and integration across Azure, SQL Server and Microsoft 365. Nearly all of it is long-lived enterprise software where an outage has a cost in the ledger and a compliance question attached.
What is .NET, and when is it the right platform?
.NET is Microsoft's application platform: C# as the language, ASP.NET Core for web services, Entity Framework for data access, and a runtime that is fast, statically typed and supported to a published date. It runs on Linux and in containers as happily as on Windows. The old assumption that .NET means a rack of expensive Windows servers stopped being true years ago, and we deploy most of it on Linux.
Two things decide it for the clients who choose it. The support schedule comes first: .NET 10 is an LTS release with a defined window, which is the sentence a company planning in three-year cycles needs to give its auditor. The second is the estate already in the building. If identity runs on Entra ID, the data lives in SQL Server, reporting is Power BI and integrations go through Azure, a .NET service drops in without a translation layer and without a second operations skill set.
On the engineering side, .NET is strong where correctness and throughput both matter. The type system catches a real class of bug before deployment, async and await are used consistently across the whole framework rather than bolted on, and throughput per server is high enough that the hosting bill for a busy API is noticeably lower than the scripted alternatives.
Where we would not push it: a content-led public site, a small product with one developer, or a team with no Microsoft footprint and no C# on staff. In those cases Node or Laravel will move faster. Most of our .NET work is adding services to an existing estate, rescuing applications stranded on .NET Framework, and building the APIs that Angular or React front-ends consume.
What we build with .NET
ASP.NET Core APIs
REST and gRPC services with OpenAPI documentation, versioning, authentication and health checks, shipped in containers.
Line-of-business applications
Blazor or MVC applications for operations, finance and compliance teams, with role-based access and an audit trail that survives review.
Framework upgrades
Applications moved off .NET Framework or an out-of-support version onto the current LTS release, in stages, with tests written before anything moves.
Integration across the Microsoft estate
Entra ID single sign-on, SQL Server, Dynamics, SharePoint and Microsoft 365 wired into your web and mobile applications.
Background services and workers
Scheduled processing, message-queue consumers and overnight reconciliation jobs, with retry policies and logs you can search.
Front-ends for .NET backends
Angular or React interfaces over an existing .NET API, without opening the business logic underneath.

.NET compared with the alternatives
.NET vs Java and Spring Boot
On capability, performance and support horizon these two are close enough that arguing about it wastes a meeting. What decides it is the estate you already run. Entra ID, SQL Server and Azure point at .NET. A JVM operations team, Kafka and an existing Kubernetes platform point at Spring. Migrating from one to the other for its own sake is money burned.
.NET vs Node.js
.NET gives compile-time type safety, higher throughput per server and a formal support schedule. Node starts faster, shares a language with the front-end, and has a much larger web hiring pool. Our rule of thumb: regulated or long-lived internal systems go .NET, product web APIs with a small team go Node.
Blazor vs a JavaScript front-end
Blazor lets a C# team build interactive screens without a second language, which is a genuine saving on internal tools with a captive audience. For public, performance-sensitive or heavily interactive interfaces, React or Angular over a .NET API is still the safer bet, and the hiring market agrees.
.NET, answered
Do we need Windows servers to run .NET?
No. Modern .NET runs on Linux and in containers, and that is how we deploy most of it, on Azure Container Apps, AWS ECS or Kubernetes. Windows hosting is only needed for old .NET Framework applications that have not been migrated yet.
Can you migrate our .NET Framework application?
Usually, and it is worth planning now. .NET Framework still gets security fixes but no new features, and the library ecosystem around it is thinning every year. We check which dependencies have modern equivalents, add tests around the risky areas first, then migrate module by module rather than betting the business on one release night.
Which .NET version do you build on?
.NET 10, the current long-term support release. We do not put client systems on short-term-support versions unless there is a specific feature you need, and then only with the follow-up upgrade already booked into the plan.
Can .NET work with our React or Angular front-end?
Yes, and it is the common shape. A .NET API publishes an OpenAPI schema and we generate the front-end client from it, so the two cannot quietly drift apart. Authentication normally runs through Entra ID or another OpenID Connect provider.
Do you work with Azure?
Yes. App Service, Container Apps, Functions, Service Bus, SQL Database, Blob Storage and Entra ID, with infrastructure defined in Bicep or Terraform so environments can be rebuilt rather than remembered.
How do you staff .NET work?
As a project team rather than an hourly role on the hire page. Send the scope and you get the team shape, the timeline and a written rate before anyone starts. If the work is really a front-end problem on top of a healthy API, we will say that too.
