I am trying to get mono (Debian 2.10.8.1-5) to run properly on my raspberry pi with the raspbian distro (\"Debian GNU/Linux wheezy/sid\"). I have installed mono with apt-get
You need to use the soft floating point OS for this. 2013-05-29-wheezy-armel.zip for example.
The hard floating point doesn't work well with JITers. I had the same issue, resolved it by installing the soft floating point version of the OS on my RP. I wouldn't recommended using .net with a hard floating point OS under the raspberry pi platform. Hope this helps.
