I'd say not focus on the negative
People who have actually used or closely seen X# do point out in the thread that X# is indeed much more than just a language to recompile VFP code, it is using the .Net framework, which is nothing like an "obscure" technology. And it is even possible to use a simple tool to directly translate X# binaries to c# code, this needs to be pointed out as well.
I think Rick's main point is that people should move away from any kind XBase development in general, the negative comments are not really directed against X# specifically. But that's a very "easy" argument to make, there are many reasons to stay with XBase. One is the existence of a huge amount of (proven to work) code that can't be "simply" rewritten. Another is how beautiful and productive it is for many of us to write XBase code.
Personally I cannot stand writing or even reading either c++ or c# code, I do all my development in X# (be it for X# itself or for other projects or just personal tools) and stay completely away from c# and hope to always keep doing that. Horses for courses though, I would not tell other people what they MUST do, everyone can just make their own research and decide for themselves what best suits them.
