[Opensim-dev] Math lib [Was:Thoughts on UUID]

[Stefan Andersson]

Totally share your sentiment,
 
but
 
ideally, we don't want to introduce native/unsafe dlls into the project
 
and,
 
as you said, given that almost everyone gets to code one up (I've done it as well) it's amazing there seem to be no good safe c# libs out there
 
really. Amazing.
 
World, please prove me wrong?
 
Best,
Stefan
