So I've been trying out the Visual Studio 2013 preview and it's really nice. Faster than 2012 certainly, but the thing that caught my attention was that it had git support built in out of the box. It's nothing super fancy, but all the basic functionality is available, meaning you don't have to open the GitHub client when you just want to make a commit or view diffs, you can do it without ever leaving the IDE.
Anyway, long story short, I did some digging and found out that Microsoft has a separate download available to add git support to VS2012, so it's not exclusive to VS2013 like I initially thought. If anyone is interested (I know some people hate GitHub's client), you can get the plugin here:
