I will fix bugs and errors in your csharp or dotnet application


About this gig
What you get
I find the cause of an error in your C# or .NET application, fix it, test it and explain what was wrong, so it does not come back.
How it works
- You send the error message, the steps to reproduce it and the relevant code.
- I check the code and tell you, in writing, whether I can fix it, with a fixed price and time.
- I fix and test it, then deliver the changed files with notes on every change.
Good to know
I work with C#, .NET (Framework and modern .NET), SQL Server and desktop or web applications. If I cannot reproduce the problem, I tell you before starting. I never need your passwords or production data.
Important
I communicate by written messages only, with regular updates. I do not offer calls or video meetings.

FAQ
Do you need access to my production system?
No. I work on a copy of the code with test data only. Please never send passwords or real customer data.
What if you cannot find the problem?
I tell you before you order, after reading the code and the error. If I cannot reproduce or fix it, I say so first, so you do not pay for a fix I cannot deliver.
Which .NET versions do you support?
Modern .NET (6 and newer) and .NET Framework 4.x, with C#. Tell me which one you use in your first message.
