Hi Connie,

Umbraco doesn't have any particular requirement, so it's really just down to taste. Personaly, of the 2 I'd prefer SVN, but that's because I'm from a mixed developer background, so prefer a less Microsoft driven solution. Given a choice of any VCS though, I'd choose Mercurial.

Don't really have any solid reasons, other than everybody else seems to be moving to distributed VCS, and it's meant to be much better at branching and merging, as well as it works better on windows than git (TortoiseHG is similar to tortoisesvn, and there is also VisualHG to plug into Visual Studio).

At the end of the day, it's whatever you / your team are most comfortable with. Each have their own strengths and weaknesses, but the most important thing is to just get your code under source control.

Matt
