ASP.net WebApp used in macOS

Hallo, My englisch is Not good But I try to ask my question :slight_smile:
It is possible to use a asp.net webApp also in macOS and in different devices? Or it is only possible With asp.net Core webapp?

Thanks for helping:)

The client can be any recent OS. The server part will only run on Windows unless you use .net core / .net 5.

Thank you for the fast and Helpfull answer SAM :slight_smile:
