ASP.NET Development in Edinburgh

Building web applications and APIs with ASP.NET Core for Edinburgh 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 Edinburgh — 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 City of Edinburgh?
Yes. We are based in Leicester, United Kingdom and work with clients throughout Scotland, including Edinburgh and the surrounding City of Edinburgh area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
What kind of Edinburgh businesses do you usually work with?
Financial services and data-led work, plus seasonal systems that have to absorb enormous August load without falling over. Beyond that we work across Financial Services, Technology, Tourism, Higher Education and Data Science.
Do you cover the areas around Edinburgh?
Yes — we work throughout Scotland, including Glasgow. Edinburgh is an urban area of roughly 540,000+, and we take on work across the wider City of Edinburgh region rather than the city boundary alone.
