.NET/Avalonia Developer for UI & Integration | AI converted VB6 Solution

@leadconcept

Greetings, I understand you need a .NET 9 / Avalonia developer to implement a modern, responsive UI for your existing C# codebase, integrating the migrated VB6 business logic, with a focus on a “Browser” window, dark mode, and audio playback via ManagedBass. The project requires MVVM-based wiring of existing classes, fault-tolerant architecture, and robust exception handling. Before proceeding, I would like to clarify a few points. 1, Any specific timeline for completing UI implementation and integration milestones. 2, Should the dark mode support theme switching at runtime or be fixed. 3, Are there any critical audio features beyond basic playback (volume, seeking, playlists). Our team specializes in Avalonia XAML, MVVM integration, and stable desktop applications in .NET, including audio library integration and resilient error handling. We focus on delivering a polished, maintainable UI aligned with your broadcast-style design reference, fully integrated with existing logic. We can provide milestone-based delivery with full source code and tested functionality. The current bid amount is a placeholder to start the conversation. Regards Yasir LEADconcept PS: Let me know, if you want to see our team past work to determine our skills/expertise or past customer's references.

Hello, I understand you’re looking for an experienced .NET/Avalonia developer to build a modern, production-grade UI and integrate it with an already-migrated C# backend originally converted from VB6. I have solid experience working on non-greenfield desktop applications where legacy logic must be preserved, stabilized, and cleanly surfaced through a modern XAML-based UI, especially in environments where reliability is critical. My approach focuses on implementing a strict Avalonia MVVM architecture that cleanly binds your existing C# business logic to a responsive, broadcast-grade user interface. I will recreate the Browser window and related views using your provided design references, applying consistent styling, a matte dark mode, and clear visual hierarchy aligned with professional audio software standards. The goal is a modern UI that feels familiar to existing users while being maintainable and extensible. On the integration side, I emphasize robustness. I implement centralized exception handling, defensive event wiring, and crash-avoidance patterns suitable for mission-critical desktop software. ManagedBass initialization and playback will be wired through your existing wrapper classes, ensuring stable audio behavior. The result is a cohesive .NET 9 desktop solution that is visually modern, fault-tolerant, and ready for long-term use. Thanks, Asif

Hello, I’m Emile. Thanks for your invite. From what I understand, you already have most of the system in place, and you’re looking for someone to build a clean, modern desktop interface and connect it smoothly to the logic you already have. The goal seems to be replacing the old style screens with a new, dark, professional looking UI, while keeping everything stable and reliable for real world use. You also want the existing audio features to work properly inside this new interface, without surprises or crashes. As mentioned before, I’m an individual freelancer, so I can work any timezone you want. Best.

@mughiraaa

Hello, I have reviewed the details of your project. i will review the existing c# codebase and solution to understand all available classes, data models, and business logic. the desktop application will be created using .net 9 with avalonia ui, following the mvvm pattern to connect the ui elements to the existing backend logic. the "browser" window will be implemented in avalonia xaml with responsive layouts and modern styling according to the provided color codes and design reference. dark mode will be added with matte finishes applied to all relevant controls. ui elements will bind to view models which call the existing c# classes to retrieve and update data. managedbass will be initialized in a dedicated audio service class and wired to playback controls in the ui, using the existing wrapper classes. global exception handling will be set up at the application level to catch unhandled errors, log them, and avoid crashes during critical operations. Let's have a detailed discussion, as it will help me give you a complete plan, including a timeline and estimated budget. I will share my portfolio in chat I look forward to hear from you. Thanks Best Regards, Mughira

@maksymh31

Hello, I will implement a modern Avalonia "Browser" window and Dark Mode, connect your migrated C# business logic via MVVM, and initialize ManagedBass for playback. I'll convert the design reference (broadcast color codes) into strict XAML styling, bind existing classes to ViewModels, and add robust global exception handling, structured logging and safe-fail patterns to meet the critical-environment stability requirement. How I will start: grant repo access and test DB, I will create a feature branch, deliver an interactive XAML prototype of the Browser window within 5 days, then complete backend binding, ManagedBass wiring, and end-to-end testing for full delivery in 14 days. What I need to start: repository access, a sample MSSQL backup or connection string, design assets, and the legacy UI screenshots. Can you provide repository access plus a sample/test MSSQL backup or connection string, and share the design reference files and legacy UI screenshots so I can prepare the prototype? Best regards,
