I will develop a custom windows desktop application in c sharp, wpf, avalonia


About this gig
WINDOWS DESKTOP SOFTWARE THAT SURVIVES PRODUCTION.
Most desktop apps on here are demos. I build the kind that runs unattended on client machines for months.
I architected an enterprise Windows control panel from scratch - real-time service monitoring, a self-healing watchdog that recovers automatically from crashes, code-signed installers and silent auto-updates. It runs today across live enterprise deployments.
WHAT I BUILD
- Custom desktop apps in C#, WPF, WinForms and Avalonia UI (cross-platform)
- Clean MVVM architecture - testable and maintainable, not spaghetti
- SQL Server, SQLite, MySQL or PostgreSQL via Entity Framework Core
- REST API and cloud integration
- Windows services, background workers, process monitoring
- Signed installers (Inno Setup / MSI) with silent auto-update
- Excel, PDF, printing and reporting features
- Modernising or fixing an existing WPF or WinForms app
WHY ME
3+ years enterprise .NET - production experience, not tutorials
Clean architecture, SOLID, commented code
Full source code and ownership
Daily progress updates, on-time delivery
Not sure which package fits? Message me what the app must do and I'll scope and quote it free.

FAQ
Will I get the full source code?
Yes, always. You receive the complete Visual Studio solution with commented code and full ownership. No licence fees, no lock-in.
WPF or Avalonia - which should I choose?
WPF if it's Windows-only: mature and huge ecosystem. Avalonia if you may later need Linux or macOS from one codebase. Tell me your target platforms and I'll advise.
Can you fix or upgrade my existing desktop app?
Yes. Send the solution or repo, I'll review it and quote a fixed price. I regularly modernise legacy WinForms and WPF applications.
Can the app work offline?
Desktop apps with a local SQLite or SQL Server database run fully offline, with optional sync when a connection returns.
Do you provide an installer?
Yes, from Standard up - a professional Inno Setup or MSI installer. Premium adds code signing and silent auto-update so users always run the latest build.
What do you need to start?
What the app must do, any screen sketches, your database or API details if they exist, and your minimum Windows version.
