UI WPF C# .NET Framework 4.6.1 translation to multiplatform (Linux+Windows)

C# — incorrectly specified categories?

I have a big old software project (desktop application on Win10) that need to be translated to be a multiplatform (Linux and Win10).

Current software has the following architecture:

1. Some BE logic in C++

2. Some BE logic in C# .NET Framework 4.6.1

3. FE in C# .NET Framework 4.6.1

4. FE UI in WPF

To transform the whole software project to be multiplatform (Linux & Windows) I will do the following for sure:

1. Adjust C++ BE code to be Linux and Windows

2. Translate BE C# .NET Framework 4.6.1 to .NET Core 8 so it will compile and run on both Linux and Windows

3. Translate FE C# .NET Framework 4.6.1 to .NET Core 8 so it will compile and run on both Linux and Windows

Here the question and a project:

4. I have a dilemma regarding FE UI WPF code - which technology is the cheaper and safer for the translation?

Is it React/ASP .NET Core/Avalonia/JavaScript/Flutter/etc.?

After I will choose a implementation platform, what else shall I implement from scratch?

How the new UI will communicate with my C# FE and BE code?

I'm searching for consultation (1st step) and then for implementation (2nd step).

For the implementation step I will provide the WPF Code and exact requirements for translation.

Currently seeking for the best technology and proposed timelines.

Good day, I won't write a bunch of meaningless text, I have experience in similar projects. Write to me to discuss the details, we will do everything in a reasonable time and at a pleasant price. At the moment, I need a rating on the project, so I would be very happy to collaborate.

Hi,

I can help you migrate your WPF UI to Avalonia quickly and with high quality. It's the best choice for your case — stable, cross-platform, and well-suited for replacing WPF on both Windows and Linux.

I'll make sure everything works smoothly and integrates properly with your existing .NET 8 frontend and backend logic. Communication between the new UI and your current codebase will be set up reliably.

Ready to start with a consultation and move on to implementation.

Hello,

I have 6 years of experience with desktop technologies.
The best technology to translate the front-end (FE) is Avalonia in this case. Since Avalonia is very similar to WPF and also runs on .NET, it is the best option.
Also, Avalonia is well-documented, and there are a lot of useful built-in controls compared to WPF, so it is the cheapest and easiest way to translate the existing WPF app.

I have experience developing apps using both technologies. You can check my portfolio.

Feel free to write me and ask questions.
