Hi there,
Once more: since this is not related to my book directly, please post questions like these in a more general ASP.NET, .NET or Visual Studio category here at
http://p2p.wrox.com. This way, you attract more viewers, and we keep this book's forum on topic so people who have the book and come here will quickly find the answers to their questions.
Also, try a Google search for questions like these for "self service". A 10-second Google search for "visual studio 2012 update" takes you here:

and here:
http://www.microsoft.com/visualstudi...-studio-update
where you can read much more on the Update for VS 2012.
Cheers,
Imar
