I need a Windows desktop application written in C# (.NET 6+ preferred) that keeps a live WebSocket connection to my server, listens for JSON messages in real time, and reacts the moment certain conditions I’ll specify are met. A REST fall-back is fine where it makes sense, but WebSocket will be the primary channel. The UI can be WinForms or WPF—whichever you feel delivers the snappiest experience—with three core controls: Connect, Disconnect, and Pause. While connected, I want a clear status indicator and a scrolling, timestamped log so I can trace every event. The app must stay responsive, so please rely on async/await or other multithreading techniques to keep network traffic off the UI thread. Automatic reconnection, graceful shutdown, and thorough exception ha...

...I expect inside the same executable (or a separate companion tool if cleaner): • List, add, disable, or delete users. • Trigger a forced resync for any user. Security matters, yet I don’t have a fixed requirement on algorithms—use standard best practice (TLS with Dropbox API, AES at rest, hashing + salt for passwords, etc.). Tech stack is up to you, though I picture C# /.NET (WinForms or WPF) talking to the Dropbox API SDK and SQL Server via SMO or sqlcmd. I’m open to alternatives as long as they run on Windows 10/11 without extra licensing costs. Acceptance criteria 1. One-click sync pulls the latest dump from Dropbox and restores it locally without manual SQL scripts. 2. The main window clearly shows “Last synced: <timestamp>&...

You’re free to choose the framework that best suits rapid, stable development—WPF, WinUI, Electron, or another option you can justify—so long as installation is straightforward for end users. The finished build should include an installer, source code, and brief setup documentation so I can update the displayed data or adjust basic styling without diving deep into the codebase. If you’ve developed similar display tools f...

...its user-interface one-for-one. You will receive the current package, screenshots of every screen, and a short walkthrough video; your job is to translate that experience into a modern, maintainable Windows executable. The core logic is in place, so the assignment is almost entirely about recreating the UI: layouts, navigation flow, dialogs, and visual behaviour. Feel free to propose WinForms, WPF, Electron, or any other Windows-friendly framework you are comfortable with as long as the final result installs easily and runs smoothly on Windows 10 and 11. Good naming conventions, clear project structure, and concise in-line comments are essential because this code will be handed to an internal team for long-term maintenance.
