FileSystemWatcher

Hi I'm using mono for a project which I want to run on more than just windows. The project involves a filesystemwatcher object to monitor several files used by the program and to trigger an update to the contents of the variables holding the contents of the files in memory.
This works fine on MS .NET but on mono (using windows and Arch linux as test systems, both with mono 1.2.5 and both fully updated) the program will not run and if --debug is specified it is revealed that it claims that the filesystemwatcher is not implemented. The mono FAQ says that any up-to-date kernel should work with it and google does not show much information on the issue.

Does anyone know how to get it working or is there a good alternative?
