You may find vsVim (https://visualstudiogallery.msdn.microsoft.com/59ca71b3-a4a3...) useful. I can't use Visual Studio without it.
VsVim doesn't cover everything, so as you start to get more advanced in your vim usage you'll start to miss features (for me at the moment, it's only partial support for folding). But it really makes every day VS so much better.
Another concern with this is pairing, as there is no easy way to turn it off. Although staying in insert mode and keeping the default bindings for VS may be OK.
