[Mono-devel-list] XPath bug + question

[Rob.Tillie at Student.tUL.EDU]

Hello Kris,

I believe Mono defines the __MonoCS__ preprocessor constant which could be
used in your case. If you just want to detect the platform you're running
on, a better method would be to detect the OS, the Environment class
probably has some methods for this.
The archives of this list contain a number of posts concerning your topic.

Greetz,
-- Rob.

PS: Nice of you to attend my presentation, I didn't expect you because you
had a class to teach. I hope it was of some use to you.
