You'll get lots of opinions about the best source control system, but I suspect nearly unanimous opinion about the worst one. VSS sucks. It stinks. It reeks. It smells of liquid, cringing, feculent death. Microsoft bought it for cheap, did a slapdash implementation to drop it into Studio, and ran away from it. The company that always eats their own dogfood doesn't use this steaming pile - they use a tweaked version of perforce (although I suspect they'll be rolling up to Team Studio). Read this page, and decide: http://www.subversionary.org/propaganda/why-not-vss Or just read this: http://support.microsoft.com/kb/q133054/ Team System might be a good choice. TortoiseSVN is an excellent choice. SourceGear vault is highly regarded. CVS is fine if you have propeller heads on staff. You would be better off entrusting your source code to a monkey with ADD and a bag of cocaine than using VSS at this point- it may have been suitable in 1995, before WANs and decent sized networking (and windows 95) but it is roadkill by any reasonable standard today. VSS is garbage, unrefined trash, and should never be used. X|
