This is a royal PITA with .net and nuget and I've get to find a half decent solution that allows you to actually have the source rather than a bunch of symbol-less dll dependencies or a ridiculous build stack.
Since MVC6/VS2015 beta you can actually get the source instead of dlls. However your build times will increase dramatically so it's a bad idea unless very needed.
