What our .NET modernization covers
.NET Framework to modern .NET
Projects and libraries moved to current .NET, with incompatible APIs replaced.
Web Forms and MVC to ASP.NET Core
Old web apps rebuilt on ASP.NET Core, or with a React front end where that serves users better.
WCF to modern APIs
WCF and SOAP services replaced with REST or gRPC APIs, keeping existing clients working during the move.
Cloud and containers
IIS and Windows Server hosting moved to Azure, AWS or containers on Linux.
Database modernization
SQL Server upgrades, Entity Framework updates and migration to managed cloud databases.
CI/CD and testing
Automated builds, tests and deployments so every release is safe and repeatable.

What we set up for London
Local payments
Languages
Data hosting
AWS Europe (London), Google Cloud europe-west2 (London) and Azure UK South, in your own cloud account, so data stays where your rules require.
How it works
1. Free assessment
We review your code, dependencies, infrastructure and data, then give you a written migration plan, risks and a fixed quote.
2. Plan and safety net
We add automated tests and monitoring around what exists today, so every change can be checked against the old behaviour.
3. Migrate in small steps
Module by module, with both versions running side by side where needed. You see progress in a demo every week.
4. Cut over and support
A planned switch-over with a rollback path, then the same engineers stay on to fix, tune and keep it current.
