After quite a bit of reading I'm beginning to understand the licensing concern over including Mono in Fedora. It does seem to be headed in that direction, but not in the short term. I suppose more lawyers have more reading to do first. At any rate, installing Mono under Core 2 was quite simple with yum. Any tips for core 3 (and yes, 3rd party bad, test version, blah blah, ... this IS how I test) installation of Mono? Can I use those same repositories as core 2? PLEASE don't tell me I'm going to have to download all the sources and build them.
