What is new in .NET 11, and should you move from .NET 10?
A fair tour of .NET 11 and C# 15 as released on 10 November 2026, the breaking changes to read first, and a decision guide for production teams on .NET 10.
· 7 min readBespoke web applications, mobile apps and integrations for medium-sized organisations, built in Cambridge and designed from the first day so that someone can look after them for years. Sometimes that means building; often it means connecting or configuring what you already have.
Most bespoke software ends up in the situation our software care service exists for, and a software health audit is the way to find out where an existing system stands: the person who built it has moved on and nobody is accountable for it. We build new software so that never happens to yours.
When it goes live you can look after it yourselves or any other supplier can, or you can bring it under software care with a named senior engineer and a named backup who also knows it.
There's more on both in our work.
Not always, and we'll tell you if you don't. Many needs can be met by configuring an existing product or connecting the tools you already use. Bespoke software makes sense when your process is a genuine advantage, or when off-the-shelf options force too many workarounds.
You do. We agree ownership of code and data in writing at the start, and we build with mainstream, well-supported technologies so you're never locked in to us.
We offer ongoing support and improvement through software care if you'd like it, and we document what we build so that any competent developer could pick it up. Your code and documentation stay in your own repository.
Yes. We build .NET MAUI apps, which let one codebase serve phones, tablets and desktops, and we migrate Xamarin apps to .NET MAUI. We built Xamarin apps in earlier years, so this is continuing work for us.
Yes. If the system is business-critical and nobody is looking after it, software care is the place to start, and a software health audit tells you where it stands. If it has reached the end of its useful life, we can talk through replacing it.

Your app is still on Xamarin.Forms and support ended in May 2024. A practical path to .NET MAUI without a rewrite: steps, sticking points and a time-boxed plan.
