It would seem that lately there are a lot of FUD-spreading trolls crawling out of the woodwork trying to frighten people into thinking that GNOME somehow depends on Mono.
Let's take a look at their most widely repeated claims:
GNOME depends on Mono
This is simply untrue... to see for yourself, try removing Mono from your Linux system using yum, zypper, or apt (or whatever) and you will plainly see that it does not remove GNOME - it may remove Tomboy, F-Spot, Banshee and/or Beagle (if you have any of them installed), but it will not remove any core components of your GNOME system.
Now that we've proven that GNOME does not depend on Mono, let's move on to their next claim:
GNOME depends on libbeagle, a Mono program
Again, false. GNOME's help browser has an optional dependency on a C-library called libbeagle which can be used to make search queries via IPC (Inter-Process-Communication) to the Beagle daemon if and only if Beagle is installed. I.E., Yelp does not depend on Beagle, it is simply able to take advantage of Beagle if it is available. As far as I'm aware, there are plans to replace libbeagle with a more generic library able to communicate with either Beagle or Tracker via IPC, depending on which one the user has installed.
NDesk-DBus is replacing DBus in GNOME
There was a big stink about this a while ago by a very angry person who didn't understand how libraries or software development in general works.
GNOME continues to depend on the C-implementation of DBus (called libdbus) and that is unlikely to change unless DBus itself (the technology, not the C-library) gets replaced.
NDesk-DBus, written by the famous Alp Toker, is a replacement for the current DBus-Sharp .NET binding around libdbus, the C-implementation. The main difference between NDesk-DBus and DBus-Sharp is that DBus-Sharp wraps libdbus while NDesk-DBus is a fully managed implementation of the DBus wire protocol.
GNOME not only does not, but it cannot, replace DBus with NDesk-DBus - any half-way competent programmer would know and understand why this is so. Native C programs cannot easily call into managed code.
Someday soon it will be practically impossible to write any app for GNOME without being forced to use MONO
Considering that in order for this to happen, core GNOME libraries would have to be rewritten in a .NET language, this is unlikely to ever happen, never mind anytime soon.
As you can plainly see, these types of claims are being made by people who do not understand the most basic concepts of software development.
GNOME is riddled with Mono applications
If by "riddled" they mean "not", then yes. ;-)
There is currently only one official GNOME application that uses Mono and that application is Tomboy. Tomboy, as useful a tool as it is, is not even arguably a core component of the GNOME desktop in that removing it will not somehow make your GNOME desktop useless.
Novell is forcing GNOME to include Mono
Ask any core GNOME developer and he or she will tell you that this is absurd. To the best of my knowledge, Novell has not even once requested that any of its Mono-based applications be accepted as core GNOME applications, never mind forced one to be accepted. I should also note that Tomboy, the only Mono application in GNOME currently, was not a Novell project at the time it as accepted for inclusion in GNOME.
