Talk to an expertMicrosoft stack at the core
C#, ASP.NET Core, Blazor, EF Core, SQL Server and Azure are what we do every day.
Migration without downtime
Strangler-pattern upgrades from .NET Framework, so users never see a cut-over weekend.
Clean architecture
Clear layers, dependency injection and tests that keep large codebases changeable.
Performance tuned
Profiling, caching and query tuning on real production data.
Modern .NET, Without the Big-Bang Rewrite
Many companies run important systems on .NET Framework, Web Forms or WCF. They still work, but they are harder to host, slower to change and increasingly hard to staff.
We migrate them incrementally. New modules are built in ASP.NET Core next to the old application, traffic moves route by route, and the legacy code is retired once nothing depends on it. Users keep working throughout.
For new products we start on current .NET with a clean architecture, automated tests and CI/CD to Azure or your preferred cloud.

Frequently Asked Questions
ASP.NET Core web applications and APIs, Blazor apps, background services, Azure cloud development, SQL Server and EF Core work, and migration of .NET Framework, Web Forms and WCF applications to modern .NET.
Yes. We review the codebase, identify blockers such as Web Forms, WCF or unsupported libraries, and migrate module by module so the application keeps running and releasing throughout.
Yes. Blazor is a good fit for internal tools and business apps where your team already works in C#. For public, SEO-critical sites we often pair ASP.NET Core with server-rendered pages or a React or Angular front end.
Yes. Most of our .NET systems run on Azure: App Service, Functions, Azure SQL, Service Bus, Storage, Key Vault and Azure DevOps or GitHub Actions pipelines. We also deploy .NET to AWS and on-premise servers.
Yes. You can hire one or more .NET developers who join your team and work on your backlog. See our Hire .NET Developers page for profiles, vetting and cost.
It depends on scope, integrations and whether it is a new build or a migration. After a short code or requirements review we give you a fixed price per milestone.
