Unfortunely, without any mobile OS to call its own, and if only WinDev was so found of adopting .NET, as Apple keeps embracing and pushing Swift, or Google with Java/Kotlin on Android.

With the recent C# focus given to WinUI and WinAppSDK, despite C++/WinRT underpinnings, maybe caused by failure to deliver VS tooling for C++/WinRT after almost a decade, or ongoing cybersecurity considerations, maybe WinDev attitute will change, although I see them more eager to adopt Rust than C#, across the Microsoftshpere blogs and technical notes.

C# is a faster Java.
