Apparently Mono 2.0 has been released today. I'm a bit surprised that I only saw a single article on the Redmond Developer website about it.

For those that don't know, Mono is a version of .Net that will run on Windows, Linux, and Mac. Although Mono provides their own C# and VB.Net compiler, it can also run code compiled by Visual Studio without any changes, though there are some compatibility issues so not all code will work (such as an pinvoke calls).

The 2.0 release of Mono is essentially .Net 3.5 minus 3.0 (no support for WPF, WCF, or WF). A couple of the nice new features in this version include support for WinForms and Xml document processing which apparently was missing in the previous release of Mono.

If you're interested in learning more about Mono or downloading it, here's a link to their website - Mono. I have not personally used Mono, but it's nice to know that the option is available.
