i highly recommend the book Illustrated C# 2012 by Daniel Solis.
That book is straight to the point on every topic if you want to learn C# fast.
Hes very good to explain the concepts with illustration and images.
Its also a very good reference book and very unique because there are useless text in it, but just straight text of what you need to know.
I think the book is perfect for you since you have experience in programming and know what it is about.
