no and yes
boo script is a language heavily based on python but uses's the .net framework not python libarys
it is not really heavily used hence why u are probably having trouble finding tutorials and documentation on it
reason being is its the worst of both python and the .net (IMO) the .net framework had a language invented for it called c# which is the best to use ,net with (again imo)
c# .net = microsoft only (can only work on microsfot system windows etc) mono project does allow small ports to unix and linux but by no means flawless and half your code will have to be re writen however .net is a full rich framework emebeded in to most of windows os and wrappers for pretty much everything you will need with in a windows environment and links in to .net web servers and allows doing huge projects quicky and easily combined with visual studio best ide probably in the world (imo)
python = small quick fun language thats not lacking in power great for scripting platform independted u can be used to do quick scripts easily no checks done untill run time but never the less a pefect langauge for small - medium size projects no so much for big projects (imo but this is heavily argued)
boo = windows only small and not fully maintained and supported ( i mean this in seance of it is maintained but not to point a problem arises on Thursday theres a hotfix for it Saturday and its limited in documentation ) hasn't got visual studio's not actually recognized by Microsoft.
ive been a .net developer since 2005 with .net 2.0 and used python since around 2007 so i would say im pretty use to both .net framework and python but even i wouldn't write anything more than 4-5 class's in boo there no point c# is there and just a quick and easy to use when using the .net framework
truth be told if u want to learn python learn python if u want to learn .net learn c# , boo as a intro to .net will probably give you more problems than it solves due to lack of documentation and tutorials
