The Black Book of .net 4.5 programming 6 in 1.
It includes 6 different programming of .Net in one book only. These 6 are 1) .Net 4.5 framework, 2) Visual Studio 2012, 3) C# 2012, 4) ASP.net 4.5, 5) VB 2012 and 6) F# 3.0.
I think this is one of the best book for .Net programmer. I have find out many solution for my personal program. The black book also gives many tips which can reduce your work also. If you want to learn professional programming from beginning than you have to purchase Black Book. Also this is very useful who know the .Net programming basically and want to upgrade. At my graduation period I am also using this Black Book but older version.
