The problem with renaming files is that if you want to take advantage of Visual Studio refactoring, you really need to do it from inside Visual Studio.
But most (not all*) version control system also want to be the ones doing the renaming.
One solution is to use integrated source control, but this is not always available, and in some cases is pretty clunky.
I'd personally be more comfortable using source control separately, outside of Visual Studio, but I'm not sure how to manage this question of file renames.
So, for those of you that use Visual Studio, which source control do you use? Do you use a VS integration (which one?) and otherwise, how do you resolve this renaming problem?
