Is it possible to run a c# application on Ubuntu?

Question

ubuntu

Good afternoon! I wrote an application for windows in c#.
Now there is a task that you need the same application only on Ubuntu. In order not to rewrite it into another language, is it possible to somehow recompile it to run it under Ubuntu?

Answer 1

If it is written under the .NET Framework and uses Winforms, it can be run on mono.
If it is written under the .NET Framework and it is console-based, you can run it on mono or migrate to .NET Core with one console command.
If it is written under the .NET Framework and uses WPF, then it can be rewritten in Avalonia and run under .NET Core.
All three methods will only work if you are not firmly attached to Windows technologies.
Personally, I recommend switching to .NET Core and making a cross-platform application.
