Awesome, good luck! New to C# in January '16, I have been using both from day 1. The test runner in RS is an improvement on the built in, but doesn't really hold a candle to NCrunch. You use Resharper for all the other good bits though :) Together, the trifecta of Studio, NCrunch and Resharper is an unbeatable combination.
Beware: I'm pretty sure I failed a job interview as I was so used to Resharper, when I needed to do a test on a PC without I was fairly lost. They had no interest in my setting up unit tests first for the programming tasks so it might have been just as well.
