Hi I’m going to kill off the mono-builds repo. When I build our mono branch or the ironruby master branch with mono ironruby gets broken for comparing Arrays the \<=\> throws a NullReferenceException When I use the binaries that are compiled on windows it works. That in combination with the fact that I haven’t really succeeded in successfully debugging a mono app from the command line make it just waste space in my account and adds to the confusion of where to get the binaries. Is there somebody on this list who could get me started debugging a mono application? * * * Met vriendelijke groeten - Best regards - Salutations Ivan Porto C.

Do you have trouble debugging Mono applications? mdb (Mono Debugger) worked fine for me debugging IronPython. Maybe I can help you. (You may contact me off-list or on Freenode IRC sanxiyn.)
