FAQ
What information should I provide before you start?
Please share the error message, screenshots, relevant source code or project files, .NET version, steps to reproduce the issue, and the expected behavior. For complex issues, please contact me before placing an order.
Can you fix bugs in an existing C# or .NET application?
Yes. I can investigate and fix issues in existing C#/.NET applications, including build errors, runtime exceptions, logic issues, WPF/MVVM problems, ASP.NET Core issues, API integration problems, and SQL-related errors.
Do you work with WPF, XAML and MVVM applications?
Yes. WPF/XAML/MVVM is one of my core areas of experience. I can troubleshoot data binding, commands, ViewModels, UI behavior, custom controls, navigation, performance issues, and other desktop application problems.
Can you work with ASP.NET Core, MVC, Web API and SQL?
The Basic package covers one small, clearly reproducible C#/.NET issue. Complex debugging, multiple related bugs, performance problems, or larger application changes may require the Standard or Premium package. Please message me first if you are unsure.
