Another file explorer option is Files [0], that looks a lot more like the built in Explorer in Windows but with some additional features.

Avalonia
Develop Desktop, Embedded, Mobile and WebAssembly apps with C# and XAML. The most popular .NET UI client technology
Check out https://avaloniaui.net as well. It's basically a cross-platform reimplementation of WPF. It's not quite as simple as C#+WinForms or Lazarus+LCL because you don't get drag-and-drop UI designer, and you need to write markup by hand (albeit with live preview). But unlike HTML, it's actually designed for desktop UI apps from the get go, so it's much easier to write for anything non-trivial. And you can still write "quick and dirty" GUI code by directly connecting event handlers to buttons and updating values etc in it, ignoring data bindings and other more advanced facilities.

MahApps.Metro
A framework that allows developers to cobble together a better UI for their own WPF applications with minimal effort.
-
Uno Platform
Open-source platform for building cross-platform native Mobile, Web, Desktop and Embedded apps quickly. Create rich, C#/XAML, single-codebase apps from any IDE. Hot Reload included! 90m+ NuGet Downloads!!
As-is today, AI tools provide some productivity gains. However, they are not replacements for experienced developers. At Uno Platform we are investing in tools which make developers productive within their current environments, such as Hot Design. Also, we are keeping a close eye and thinking of these useful scenarios to apply AI to, as we don’t believe just adding a simple LLM to it will actually add value. So, stay tuned to our blogs and Dev.to account as there is more goodness coming on this topic.

ComputeSharp
A .NET library to run C# code in parallel on the GPU through DX12, D2D1, and dynamically generated HLSL compute and pixel shaders, with the goal of making GPU computing easy to use for all .NET developers! 🚀
> RISC-V
The work is underway: https://github.com/dotnet/runtime/pulls?q=label%3Aarch-riscv
> PTX
https://ilgpu.net/ and even https://github.com/m4rs-mt/ILGPU/blob/c3af8f368445d8e6443f36...
While not PTX, there's also this project: https://github.com/Sergio0694/ComputeSharp which partially overlaps with what ILGPU offers
Arguably, even C++ itself - you are not using "full" C++ but a special subset that works on top of specific abstraction to compile to GPUs, and I was told that CUDA C++ is considered legacy.
The original context of discussion is performance and perceived issue of "having runtime", which is what my reply is targeted at. In that context, C# provides you the tools and a solution other languages in the class of Java, Go, TS and anything else interpreted just don't have. So you could reasonably replace a project written in C++ with C#, and possibly re-apply all the freed-up developer productivity into further optimizations, but you wouldn't be able to do so with the same degree of confidence with most other originally high-level languages. Another upcoming contender is Swift.
