About this gig

Your business still runs on a VB6 or old .NET Framework application. It works, but it's hard to install on new PCs, nobody wants to touch the code, and every Windows update feels risky.


I migrate legacy desktop apps to modern C# on .NET 8 (LTS), keeping the same behavior your team already knows.


What I migrate:

  • Visual Basic 6 applications
  • VB.NET applications (to C#)
  • .NET Framework 2.0 to 4.8 WinForms and WPF apps
  • Old data access (ADO, DAO, inline SQL) to safe, parameterized SQL Server queries

How it works:

  1. Assessment: I review your code and give you a plan, the risks and a fixed price. No surprises.
  2. Migration in small steps, so you can test progress along the way
  3. Delivery: full source code that builds in Visual Studio 2022, plus notes on what changed

Example from my portfolio: a legacy WinForms inventory app rebuilt in WPF on modern .NET, with search, low-stock alerts and Excel export. 500 products load in 0.2 s without freezing.


Your code stays private and I'm happy to sign an NDA. Start with the Assessment package if you're not sure how big the job is.
