If you already have an application written in .Net, you can scan your application with the Mono Migration Analyzer (MoMA) to determine if your application uses anything not supported by Mono.

The current release version of Mono is 2.6. (Released December 2009)

The easiest way to describe what Mono currently supports is:
Everything in .NET 3.5 except WPF and WF, limited WCF.
