We've used Perforce source control for a number of years. It's a great tool and it integrates with Visual Studio pretty well. But its Visual Studio integration has one really annoying feature, that fortunately, you can work around. The feature is this: If your solution has 10 projects in it, you can put each of those 10 projects in a separate Perforce Depot. Is that useful? I'll leave that to you. Suffice it to say that we put all our source in one Depot. The problem comes when you reload a solution....
