What you need for this book

All the code samples have been prepared and tested using Microsoft Visual Studio 2013, which brings the highest integration with Version 2 of SignalR with it. Microsoft Visual Studio 2012 could be used too, and you would be able to reach the same final result, but the experience inside the IDE might be slightly different. Again, the book will not try to fill any gap between the two environments, and it will explicitly only target the 2013 version.
