This link was posted here in recent weeks by the package maintainer for mono on Fedora (or maybe he's OpenSUSE?). It has packages of mono 3.2.3 and related projects like libgdiplus and monodevelop for Fedora, Debian, and related distros. I hope you find this helpful.
Are there any plans/issues for bringing Mono 3.x to fedora? current mono version is 3.2.4.
