Which UI should I choose to migrate my C# desktop app to Azure?

I have developed my c# console app far enough that I'm ready to start on the UI portion.

I want to deploy this to Azure so that users on various platforms, in various locations,  can run my app .

Is a WinForms UI a reasonable choice to achieve this?

I'm most familiar with Winforms development.

If not, what is? ASP.Net? Xamarin?

I'd need to learn these skills to develop in them.

Thanks,

Hal
