Question

What apps/websites did you guys use to learn C#? Please only say Free sites/apps :)

Answer 1

C# Programming Yellow Book and other books by RobMiles.com at http://www.csharpcourse.com/

Answer 2

For me, it came to a point where websites and videos were lacking in substance and books were the most complete and straight forward approach to continue learning programming. I started off with something like Heads First C#, but there are probably better ones out there.
