ASP.NET Development in Cambridge
Building web applications and APIs with ASP.NET Core for Cambridge organisations, where service lifetimes cause the subtlest bugs in the framework. A scoped service captured inside a singleton outlives the request it belonged to — so a database context intended to last one request lives for the life of the application, and the symptoms appear far from the cause.
Why this comes up
The problem
A database context is being reused across requests, connections leak, and the errors point at code with nothing wrong with it.
What you get
What we deliver
- Service lifetimes chosen deliberately, with captive dependencies avoided
- Database contexts scoped correctly and never held by longer-lived services
- Configuration bound to typed options and validated at start-up
- Minimal APIs or controllers chosen for the shape of the application, not by habit
- Cancellation tokens honoured so abandoned requests stop doing work
- Health checks and structured logging in place before production, not after

ASP.NET Development in Cambridge — common questions
- What is a captive dependency?
- A short-lived service held by a long-lived one. Injecting something scoped into a singleton means the singleton keeps that instance forever, so a per-request object silently becomes application-wide — and the resulting errors surface as unrelated data or connection problems.
- How do we catch it?
- Enable scope validation, which the framework can do at start-up. It refuses to start when a lifetime is captured incorrectly, turning a class of subtle runtime bug into a clear failure before anything is serving traffic.
- Minimal APIs or controllers?
- Minimal APIs suit small focused services and controllers suit larger applications with conventions, filters and shared behaviour. Both are supported and the choice should reflect the size and shape of what you are building rather than which is newer.
- Why do cancellation tokens matter?
- Because abandoned requests otherwise keep working. A user who navigates away leaves a query running against your database, and under load that wasted work compounds — honouring cancellation through to the data layer frees capacity nobody is waiting on.
- Do you work with businesses across Cambridgeshire?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout East of England, including Cambridge and the surrounding Cambridgeshire area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Cambridge businesses do you usually work with?
- Deep-tech and biotech clients bring genuinely technical briefs, often involving data pipelines, instrumentation or research tooling. Beyond that we work across Technology, Life Sciences, Research, Higher Education and Biotech.
- Do you cover the areas around Cambridge?
- Yes — we work throughout East of England, including Norwich, Milton Keynes, London, Northampton. Cambridge is an urban area of roughly 150,000+, and we take on work across the wider Cambridgeshire region rather than the city boundary alone.
