I will fix, assess or migrate your legacy dotnet app to dotnet 10 lts
Malavos
About this gig
Your .NET app still works, but it's stuck on an old version? Microsoft ends support for .NET 8 and .NET 9 on November 10, 2026, and .NET Framework apps can't use modern tooling. .NET 10 is the current LTS release, supported until November 14, 2028.
I have 10+ years of C# and .NET, including leading the modernization of legacy desktop stacks into modern .NET. Today I lead DevOps for a 24x7 platform on AWS, so your app also leaves ready to build in a container.
What you get:
- Basic: one reproducible bug or build error fixed (up to 3h of work), with the cause explained
- Standard: a migration assessment (projects, NuGet packages, incompatible APIs, step-by-step plan and estimate) plus one class library ported to .NET 10
- Premium: a small app (up to ~3 projects) migrated to .NET 10, with build and tests passing, a Dockerfile and deployment notes
I migrate incrementally, with as few code changes as possible, instead of rewriting your app. Bigger apps get a custom offer after the assessment. Questions? Send me a message before ordering.

FAQ
Why .NET 10?
It's the current LTS release, supported until November 14, 2028. .NET 8 and .NET 9 reach end of support on November 10, 2026 (Microsoft's .NET support policy).
Does my app need to be .NET Core?
No. .NET Framework 4.x apps are welcome. The assessment tells you what blocks the move and how big the job is.
Will you rewrite my app?
No. The goal is to move what you have with as few code changes as possible.
What if the bug can't be reproduced or takes longer than 3h?
I'll tell you before going further and send a custom offer.
My app is bigger than 3 projects.
Start with the assessment (Standard). I'll send a custom offer for the full migration.
What do you need from me?
Read access to the repository. Never send production credentials by message.
Is there a call?
No. Everything is handled through Fiverr messages.
