How does C# fares in terms of portability these days? I checked years ago, and at the time, for non-Windows OSes you had to use Mono. But whether your application was going to work or not also depended on which graphic libraries you were using, e.g. WinForms wasn't going to work on Mono. At the time, C# was presented to me as a better Java, but to me it seemed that Java had true cross-platform compatibility while C# was going to work nicely only on Windows, unless you had some proper planning of checking beforehand which libraries were working with Mono.
