Keep your .NET applications supported, secure and cheap to run
I've built ASP.NET applications since the first release and ASP.NET Core since version 1. If your business depends on an older .NET application, I'll upgrade it to a supported version, move it to modern hosting and leave it easier to maintain. You won't need to rewrite from scratch.
Sound familiar?
- .NET 8 and .NET 9 both reach end of support on 10 November 2026, after which they get no security patches
- A business-critical app runs on .NET Framework and nobody wants to touch it
- Hosting costs keep rising and the app can't move to containers or the cloud
- The original developer has moved on and the codebase is a black box
What you get
- Upgrade audit: dependency and risk analysis, and a costed migration plan
- Incremental migration to .NET 10 (LTS, supported until November 2028)
- Automated tests around critical paths before anything changes
- Containerisation and a move to Azure, AWS or modern Windows/Linux hosting if needed
- CI/CD pipeline so future updates are routine
Ways to work together
Every engagement starts with a small, paid, fixed-price first step. That's where requirements are gathered and the scope and cost estimate for the rest of the work are written, so you know what you're committing to.
